Is That Planet Habitable? Look To The Star First, New Study CautionsBy Elizabeth Howell October 7, 2013 Elizabeth Howell Previous Article ← Astrophoto: Uranus at Opposition Next Article Mercury's Resonant Rot
Since 2009, the Kepler mission has tallied 989 confirmed exoplanets in the Milky Way; once the James Webb telescope launches in 2018, that number should rise. But do any of these have conditions as cushy as ours-what astronomers call "superhabitable"? To make a ballpark assessment, a team ...
Gaia-4b is a massive exoplanet with about 11.8Jupitermasses. It follows a 571-day orbit around a star with a mass of 0.644 solar masses. It has the distinction of being the first confirmed exoplanet found by Gaia. It’s also one of the most massive planets that have ever been detected...
3. Earth's Counterpart: When specifically referring to Earth, "planet" highlights the unique characteristics that make our planet habitable, such as its suitable distance from the sun and the presence of water.4. Environmental Protection: In discussions about sustainability and environmental...

Although Proxima b orbits much closer to its star than Mercury does to the Sun in the Solar System, the star itself is far fainter than the Sun. As a result, Proxima b lies well within thehabitable zonearound the star and has an estimated surface temperature that would allow the presence...
Bill Borucki, Kepler principal investigator at NASA Ames Research Centre, said: "We have now got good planet confirmation with Kepler 22b. We are certain that it is in the habitable zone and if it has a surface it ought to have a nice temperature." There are now three planets outside th...
