Scale from Brad Goodspeed on Vimeo.

This is great! Blogger Brad Goodspeed created an animation which shows different planets in our solar system as they would appear in the sky if it shared an orbit with our Moon, 380,000 km from earth. On his blog, he said he created it “to make you feel small.” You succeeded, Brad!

He explains how he created the video on his blog, BradBlogSpeed.com

Heh, Jupiter is HUGE. That would be well inside the Roche limit of Jupiter though, wouldn’t it? So you couldn’t ever actually have that view from a reasonably sized body.

As far as I can remember Io orbits at about 420,000km, So another 40K to the Roche limit? I’m not sure what effect the increased size of the earth would have, but we might be able to orbit Jupiter at that distance.

If not, there would still be some serious tidal effects, assuming we still had a 24hr day…

imagine kilometers high waves sweeping whole continents every day…after few years (or centuries?), there would be no land left, just a water world eventually freezing out to Europa’s big twin moon.

With Neptune and Jupiter these planets would not be orbiting the Earth so much as Earth would orbit them.

And even with mars we may be orbiting a common center of Gravity that is in space, similar to Pluto and Charon.

What? No Uranus, Neptune, Pluto, Quaoar or Sedna?

Oops… Neptune WAS included..

Quasars, SMBH AGN, Blazars, Radio, Seyferts, Spiral, Active Galaxies all are the same phenomena dependent upon the viewing alignment direction of the observer. NASA and ESA say it is believed by most astronomers today by an evolving unified galaxy model, the most accepted is that blazars are nearly directly aligned jets. Quasars are all sky and where less dust obscures the AGN at a 45 degree 3D orientation. Radio galaxies conceal the AGN aligned with their torus of gas and dust. We would appreciate comments about our Holographic Galaxy Unified Model.

Firstly I hope this and your comment are deleted. It is blatant advertising, from someone who is not even interested in the topic here!
Really. What has this to do with planetary scales?
I can only conclude you don’t know the difference, which then means you don’t know what you’re talking about, and you’re wasting everybody’s time. If do know the difference, the your just as silly.
So if you want to “appreciate comments”, here’s one, its simply balderdash!

Have a nice one… whatever your name is!!
