Kepler-90b (also known as KIC 11442793b), is a super-Earth exoplanet with a radius 1.31 times that of Earth, orbiting the G-type star Kepler-90 every 7.008 days. It was discovered by the Kepler telescope in October 2013.
Characteristics
Kepler-90b orbits Kepler-90 every 7.008151±0.000019 days,[1] at a distance of 0.076 AU.[2] It is in a 5:4 resonance with Kepler-90c.[2] It has a mass of 0.0082 MJ,[3] and a radius of 1.31±0.17 R🜨,[1] making it most likely a rocky planet.
Host Star
The planet orbits a G-type star named Kepler-90, its host star. The star is 1.2 times as massive as the Sun and is 1.2 times as large as the Sun. It is estimated to be 5.8 billion years old,[4] with a surface temperature of 6080 K.[1] In comparison, the Sun is about 4.6 billion years old[5] and has a surface temperature of 5778 K.[6]
