Astronomers are Starting to Find Planets in Much Longer Orbits. Cooler, More Habitable Planets

This artist’s view shows the planet orbiting the young star Beta Pictoris. This exoplanet is the first to have its rotation rate measured. Its eight-hour day corresponds to an equatorial rotation speed of 100 000 kilometres/hour — much faster than any planet in the Solar System.

We’re getting better and better at detecting exoplanets. Using the transit method of detection, the Kepler Space Telescope examined over 530,000 stars and discovered over 2,600 explanets in nine years. TESS, the successor to Kepler, is still active, and has so far identified over 1800 candidate exoplanets, with 46 confirmed.

But what if, hidden in all that data, there were even more planets? Astronomers at Warwick University said they’ve found one of these “lost” planets, and that they think they’ll find even more.

Exoplanet Orbits its Star Every 18 Hours. The Quickest Hot-Jupiter Ever Found

In the past decade, thousands of planets have been discovered beyond our Solar System. These planets have provided astronomers with the opportunity to study planetary systems that have defied our preconcieved notions. This includes particularly massive gas giants that are many times the size of Jupiter (aka. “super-Jupiters”). And then there are those that orbit particularly close to their suns, otherwise known as “hot-Jupiters”.

Conventional wisdom indicates that gas giants should exist far from their suns and have long orbital periods that can last for a decade or longer. However, in a recent study, an international team of astronomers announced the detection of a “hot-Jupiter” with the shortest orbital period to date. Located 1,060 light-years away from Earth, this planet (NGTS-10b) takes just 18 hours to complete a full orbit of its sun.

A Very Rare Planet Discovered. Less Massive than Neptune, Hotter than Mercury. Very Few Should Exist

Astronomers have discovered a very rare, very unusual planet in a distant solar system. The planet, called NGTS-4b, is three times the size of Earth, and about 20% smaller than Neptune. It’s hotter than our very own Mercury. At about 1,000 degrees Celsius, it would be the hottest planet if it were in our Solar System.

But what really separates this planet is its location. It’s located in what’s called the Neptunian Desert.
