Star Systems and ExoPlanets: 201 to 400 Light Years Away from Earth

There are currently 111 stars and 41 planets listed from 201 to 400 light years from our Solar System.

The stars in this range represent 87 Star Systems and 9 of these Star Systems have multiple planets.

The total planet count for this range includes 1 Mercurian planet, 3 Sub-Terran planet, 5 Terran planets (Earth-Size), 8 Super Terran planets, 2 Sub-Neptunian planets, 3 Neptunian planets, and 19 Jovian planets.

There are 0 planets in this range that have been confirmed to harbor intelligent life.

There is 1 planet in this range that is in the habitable zone of its star and might potentially harbor intelligent Alien life.

Kepler 446 b the most notable planet within the 201 to 400 light year planet list. Kepler 446 b is a Warm Super Terran that orbits in the habitable zone of its star. Is Kepler 446 b home to an intelligent Alien civilization?

Planets have also been categorized according to their ESC, or Earth Similarity Class. Some scientists call this the Earth Simiarlity Index, or ESI. ESC is an indicator of how "Earth-like" a planet may be, based upon the following 20 criteria: 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), axial tilt, orbit eccentricity, size, mass, diameter, density, gravity, atmosphere, atmosphere pressure, ozone layer, magnetic field, parent star solar flares, average temperature, liquid water, land, plants, animals, and intelligent beings.

Planets outside of our solar system have ESC's calculated given the current data that is available. Their real ESC may rise or fall once complete data has been discovered. ESC will only be calculated for rocky planets and not for Gas Giant planets. ESC does not nessarily indicate that a planet is "habitable" or can support life as we know it. ESC only gives us a general indication about how that planet compares to Earth given currently available data. Images that are displayed for planets are theoretical based upon the current available data. Images may be updated as new planetary data is discovered.

In addition, any planet that has a green background, is located within the "habitable zone" of that star. The habitable zone of a star is defined as the area around a star where liquid water could possibly reside on a planet, given that the planet has sufficient atmospheric pressure and a temperature that allows for liquid water. It does not indicate that a planet will be "habitable" just because it's located within that star's habitable zone. Also, any planet that has an orange background, is located in the habitable zone, however, the planet is bombarded by strong solar flares from its parent star. Finally, any planet that has a red background, is located in the habitable zone, however, the planet is bombarded by extreme solar flares from its parent star.
