Kepler-69c (also KOI-172.02 ) is an exoplanet orbiting the star Kepler-69 in the constellation Swan . It was discovered in 2013 using the transit method through the Kepler Space Telescope .
Initial analyzes came to the conclusion that Kepler-69c could be in the habitable zone . The planet is roughly 60 percent larger than Earth, making it a super-earth category . Further investigations, however, suggest that, due to the short distance to the star, it is more of a supervenus , on which no life can arise according to today's ideas.
Orbit
The planet orbits its central star Kepler-69 at a distance of 0.64 AU in 242.46 days with an orbital inclination of 89.85 °. In addition to Kepler-69c, another planet was discovered with Kepler-69b , which orbits Kepler-69 in 13.72 days.
