description Kepler-90c Overview
Kepler-90c is a transiting super-Earth exoplanet in the Kepler-90 system, which contains eight known planets orbiting a G-type star. NASA lists a radius of about 1.19 Earth radii, a mass of about 1.81 Earth masses, and an orbital period of 8.7 days at a distance of 0.089 astronomical units from its star. Its short orbit places it among the close-in inner planets of the system, not in an orbit comparable to Earth's. [NASA Science](https://science.nasa.gov/exoplanet-catalog/kepler-90c/)
help Kepler-90c FAQ
How large is Kepler-90c?
NASA lists Kepler-90c at about 1.19 times Earth's radius and about 1.81 Earth masses. Those values identify it as a super-Earth by size and mass, although that label does not by itself describe its habitability.
How long is a year on Kepler-90c?
Kepler-90c completes an orbit in about 8.7 days. It circles its host star at roughly 0.089 astronomical units.
What star system contains Kepler-90c?
Kepler-90c belongs to the Kepler-90 system, which has eight known planets. The host star is a G-type star, like the Sun in broad stellar classification.
How was Kepler-90c found?
It is a transiting exoplanet, meaning it was detected as it passed in front of its star and caused a small dip in starlight. The Kepler mission used this transit method to identify planets in the Kepler-90 system.
