Is There Really a Planet X?

Is There Really a Planet X?

Have you heard there’s a giant planet in the Solar System headed straight towards Earth?

At some point in the next few months or years, this thing is going to crash into Earth or flip our poles, or push us out of our orbit, or some other horrible civilization destroying disaster.

Are these rumours true?

Is there a Planet X on a collision course with Earth?

Unlike some of the answers science gives us, where we need to give a vague and nuanced answers, like yes AND no, or Maybe, well, it depends…

I’m glad to give a straight answer: No.

Any large object moving towards the inner Solar System would be one of the brightest objects in the night sky. It would mess up the orbits of the other planets and asteroids that astronomers carefully observe every night.

There are millions of amateur astronomers taking high quality images of the night sky. If something was out there, they’d see it.

These rumours have been popping up on the internet for more than a decade now, and I’m sure we’ll still be debunking them decades from now.

What people are calling Planet X, or Nibiru, or Wormwood, or whatever doesn’t exist. But is it possible that there are large, undiscovered objects out in the furthest reaches of Solar System?


Astronomers have been searching for Planet X for more than a hundred years. In the 1840s, the French mathematician Urbain Le Verrier calculated that another large planet must be perturbing the orbit of Uranus. He predicted the location where this planet would be, and then German astronomer Johann Gottfried Galle used those coordinates to discover Neptune right where Le Verrier predicted.

The famed astronomer Percival Lowell died searching for the next planet in the Solar System, but he made a few calculations about where it might be found.

And in 1930, Clyde William Tombaugh successfully discovered Pluto in one of the locations predicted by Lowell.

Astronomers continued searching for additional large objects, but it wasn’t until 2005 that another object the size of Pluto was finally discovered by Mike Brown and his team from Caltech: Eris. Brown and his team also turned up several other large icy objects in the Kuiper Belt; many of which have been designated dwarf planets.

We haven’t discovered any other large objects yet, but there might be clues that they’re out there.

In 2012, the Brazilian astronomer Rodney Gomes calculated the orbits of objects in the Kuiper Belt and found irregularities in the orbits of 6 objects. This suggests that a larger object is further out, tugging at their orbits. It could be a Mars-sized object 8.5 billion km away, or a Neptune-sized object 225 billion km away.

There’s another region at the edge of the Solar System called the Oort Cloud. This is the source of the long-period comets that occasionally visit the inner Solar System. It’s possible that large planets are perturbing the orbits of comets with their gravity, nudging these comets in our direction.

So, feel free to ignore every single scary video and website that says an encounter with Planet X is coming.

And use that time you saved from worrying, and use it to appreciate the amazing discoveries being made in space and astronomy every day.

Most Awesome Space Images of 2012

Each year, we are simply stunned by the beautiful images of space shot from a growing myriad of eyes that stare toward the heavens. This year was no different. From views out of the portholes of the International Space Station and landscapes of Vesta and Saturn to the faraway vistas from Hubble, Chandra and Spitzer sit back and stare in awe at the vastness of the cosmos with this look back at the most awesome space images of 2012

Astronauts aboard the International Space Station used their lofty perch to take some awesome images of Earth in 2012.


Expedition 33 crew look at exhaust trails from the Soyuz rocket that blasted off from the Baikonour Cosmodrome in October heading toward a rendezvous with the ISS. Exhaust plumes curled in different directions due to winds blowing in different directions as the rocket ascended through various atmospheric layers.



Astronauts shot an image of delicate shining threads called polar mesospheric clouds as they zoomed across the Tibetan plateau in June 2012. Also known as noctilucent or night-shining clouds, this image is the first time astronauts caught the phenomenon from orbit.



Sea ice forms along the Pacific coastline of the Kamchatka Peninsula in this image from Expedition 30 in March 2012. Large circular eddys spin off from the southwestward flowing Kamchatka current. While the sea ice looks thin and delicate, the smallest features in this image are several meters across. North is to the left in the image.



The ISS was sailing over Nova Scotia when astronauts caught sunglint reflecting off the Great Lakes of North America. Featured in the image are New York’s Finger Lakes, Lake Ontario, Lake Huron and Lake Erie. Most of Canada is hidden under a blanket of clouds toward the curving horizon in this image.

Nearly as dazzling as the images, the skill of Cassini imaging team at finding unique shots is impressive. The bright moon Enceladus sits before the rings with the larger moon Titan glowing dimly in the distance. Cassini took this image in April 2012 from a distance of about 600,000 miles (1 million kilometers) from Enceladus.

The ‘Bonus’ Full Moon of 2012

The full Moon today is considered a bonus for 2012, since it is the 13th full Moon of the year. But this full Moon has also been a bonus in the sense that we’re getting several nights in a row of nearly full Moons. According to Universe Today’s Phases of the Moon App, the face of the Moon on the night of the 25th was 96% illuminated; on the 26th it was 99% illuminated; the night of the 27th/morning of the 28th was the full Moon, (officially, the Moon was most full at 10:21 UTC (4:21 EST this morning), and tonight, the 28th, the face of the Moon is again 99% illuminated. And if you’re enjoying a wintery landscape like I currently am, the brilliance of the Moonlight on snow is bright enough to keep you awake at night.

Enjoy some great astrophotos submitted for photographers around the world of the bonus — and final — full Moon of 2012.

Our friend César Cantú sent us this image today, and it seemed perfect to share on the day where nothing apocalyptic happened. Hopefully, the day turned out for all our readers as only a chance to have a party and share a few jokes, to realize the specialness of those around you, or just to finish up your holiday preparations.

As someone once said, “Live long and prosper,” and as 2012 comes soon to a close, that is our wish to all of you.

(That, and please don’t believe any of those crazy doomsday prophesies anymore.)

NASA’s Final 2012 Doomsday Debunking Video (We Hope)

Despite countless articles published over the course of several years to the contrary, despite videos and interviews with some of the world’s most prominent and well-respected astronomers, despite new archaeological discoveries and well-established knowledge, despite the laws of physics, for crying out loud (and, curiously enough, even despite the fact that parts of the world are, at the time of this writing, already well within the supposed “doomsday” with nary a Nibiru in sight) many people are still wondering what will happen on the much-touted December 21, 2012, aka “doomsday” per the end of the 13th b’ak’tun of the Maya calendar (or something like that.) After all, if it’s trending on Twitter it must be important, right?

Well, yes and no. No because there’s not a shred of truth to the whole thing (except for the fact that there were Maya and they had a calendar) but yes because many people are actually very concerned about… well, I guess about the safety of the world. (Don’t believe me? Read this.) Which is in itself reasonable, I suppose. So in the nature of public outreach and the attempt to spread real information to combat the other kind, NASA’s has released yet one more video interview with astrophysicist David Morrison, director of the Carl Sagan Center for Study of Life in the Universe at the SETI Institute. I don’t know if David could tell you how to replace a broken head gasket or perform an appendectomy, but when it comes to space he knows his stuff. So check out the video, be not alarmed, and pass it on to anyone you know who might still be feeling the b’ak’tun blues.

See you on the 22nd! (Still skeptical? Check out some other videos and links below.)

And here’s a “reality check” from JPL’s Don Yeomans, an expert on near-Earth objects and asteroids:

So rest assured, the only astronomical event expected for the 21st is the winter solstice (summer in the south), which happens every year on every planet with an axial tilt with no ill effects (besides perhaps a sudden sinking realization that you’re nowhere near done with your holiday shopping.) Happy solstice!

The Truth About 2012: Killer Solar Flares Are a Physical Impossibility

NASA is trying to make sure that no one is taking the 2012 doomsday nonsense seriously, and just put out this video today detailing how a gigantic “killer solar flare” just ain’t gonna happen. Dr. Alex Young from the Goddard Space Flight Center explains how the Sun’s regular 11-year solar cycle is expected to peak in 2013 and 2014, not on December 21 of this year. Plus, this current solar cycle has been kind of a dud as far as wild activity goes, and scientists are not expecting the peak of this cycle to even be as strong as the previous one, which was rather mild.

Not to mention, Earth’s atmosphere keeps us well protected here on Earth. The only thing we do have to be concerned with is how solar flares and coronal mass ejections (CMEs) can damage satellites and even impact the power grid on Earth; additionally astronauts in Space to have to be specially protected as they are outside of the protection of the atmosphere.

You can get more information in our detailed article “2012: No Killer Solar Flare.”

What Earth Looked like on 12/12/12

Although we don’t subscribe to hokum like numerology or think that dates on a man-made calendar could have any sort of cosmic significance, there is something about a little symmetry. The GOES-15 satellite captured this image of Earth today, which is 12/12/12 on the Gregorian calendar, and even added a bonus of taking the image at 1200 UTC.

Too bad the GOES-12 spacecraft had some thruster problems and is currently in a standby mode.

Dennis Chesters, project scientist of NASA’s GOES Project at the NASA Goddard Space Flight Center said this image does something significant, however: the fourth tropical cyclone in the southern Pacific Ocean. Newborn Tropical Storm Evan was born today, Dec. 12, 2012 at 1500 UTC (10 a.m. EST) and appears as a rounded area of clouds in the bottom left corner of the image. Tropical Storm Evan is about 145 nautical miles west of Pago Pago, American Samoa.

Google’s 2012 Year in Review Includes Space Highlights

Even though this is a promotional video by Google, it is a great review of 2012, good and bad. And there’s a plethora of space-related events and people featured. Look for: Felix Baumgartner’s jump, SpaceX’s Dragon launch, the search for the Higgs Boson, space shuttles, Curiosity’s landing, Neil Armstrong, Sally Ride, Ray Bradbury, the International Space Station, solar eclipse, and more.

As the Very Short List folks said, this video is “also an inspired reflection of our collective hopes, dreams, fears, and desires.”

In the Shadow of the Moon: Experience a Solar Eclipse From 37 Kilometers Up

The Moon’s shadow stretches over the Earth in this balloon-mounted camera view of the November 14 solar eclipse (Catalin Beldea, Marc Ulieriu, Daniel Toma et. al/Stiinta&Tehnica)

On November 14, 2012, tens of thousands of viewers across northeastern Australia got a great view of one of the most awe-inspiring sights in astronomy — a total solar eclipse. Of course many fantastic photos and videos were taken of the event, but one team of high-tech eclipse hunters from Romania went a step further — or should I say higher — and captured the event from a video camera mounted on a weather balloon soaring over 36,800 meters (120,000 feet) up!

Their video can be seen below:

During a solar eclipse the Moon passes in front of the disk of the Sun, casting its shadow upon the Earth. Any viewers within the darkest part of the shadow — the umbra — will experience a total eclipse, while those within the wider, more diffuse shadow area along the perimeter — the penumbra — will see a partial eclipse.

By launching a weather balloon carrying a wide-angle camera into the stratosphere above Queensland, eclipse hunter and amateur astronomer Catalin Beldea, ROSA research scientist Florin Mingireanu and others on the team were able to obtain their incredible video of the November 14 total eclipse from high enough up that the shadow of the Moon was visible striking Earth’s atmosphere. Totality only lasted a couple of minutes so good timing was essential… but they got the shot. Very impressive!

The mission was organized by teams from the Romanian Space Agency (ROSA) and  Stiinta&, with the video assembled by Daniel Toma and posted on YouTube by editor-in-chief Marc Ulieriu. Music by Shamil Elvenheim.
