description Kepler-20f Overview
Kepler-20f is a near-Earth-sized exoplanet orbiting the sun-like star Kepler-20, located approximately 929 light-years from Earth in the constellation Lyra. Confirmed alongside Kepler-20e in December 2011 by NASA's Kepler space telescope, the planet has a radius roughly 1.03 times that of Earth, making it almost identical in size to our own planet. However, with an orbital period of about 19.5 days, it orbits much closer to its host star and has an estimated surface temperature of over 400 degrees Celsius, making it too hot to sustain liquid water on its surface.
help Kepler-20f FAQ
How big is Kepler-20f compared with Earth?
Kepler-20f has a radius of roughly 1.03 times Earth's radius, making it near-Earth-sized. That size does not by itself prove that the planet has Earth's composition or atmosphere.
When was Kepler-20f confirmed?
NASA's Kepler space telescope confirmed Kepler-20f alongside Kepler-20e in December 2011. The planets orbit the star Kepler-20 in the constellation Lyra.
Is Kepler-20f in the habitable zone?
No. Kepler-20f orbits too close to its Sun-like star to be in the conventional habitable zone where liquid surface water could persist.
How far away is Kepler-20f?
Kepler-20f is approximately 929 light-years from Earth in the constellation Lyra. It is part of the Kepler-20 planetary system.
