Milky Way Galaxy Atlas


Planet Note: The following list of planets are the ones that are closest to being Earth-like given the amount of data that is currently available. It should not be assumed that a planet is in any way habitable like Earth just because it appears in this list. There is much more data that must be gathered about these planets to determine how truly "Earth-like" they may be.

For a Planet to be considered "Earth-Like", it must meet 11 criteria. These criteria in no way indicate that other planets that are not "Earth-like", are not habitable. A planet that is not "Earth-like" may still be habitable. However, these criteria simply provide us with a framework to determine how closely a planet may resemble Earth, and thus whether life as we know it could possibly inhabit such a planet. Each criteria also has a color associated with it. These colors are defined in the
Galaxy Legend, and give a general idea of how a planet ranks within the framework of the Earth Similarity Class. Any criteria that is "green," means that the planet meets that criteria for being an "Earth-like" planet.

The 11 Criteria are as follows: whether a planet is in the habitable zone of their star (the area where liquid water could exist), if the planet is tidally locked (one side always faces its star), if the planet is subjected to intense solar flares from its parent star, size class, mass, density, diameter, atmospheric pressure, atmospheric composition, average global temperature, and whether it has liquid water.

At this point, some of these planetary properties must still be refined and more accurately measured, and are subject to change given future data.

The planet that is currently the most Earth-like found to date is the planet Kepler 186 f. Kepler 186 f is located 490.00 light years from Earth.
