description Kepler-10c Overview
Kepler-10c is a transiting exoplanet orbiting Kepler-10, a Sun-like star also known to host the rocky planet Kepler-10b. With a radius of about 2.35 times Earth's, it was initially described as a massive, potentially rocky "mega-Earth" after an early mass estimate near 17 Earth masses. Later measurements yielded a lower and less certain mass, weakening the original rocky interpretation and making a volatile-rich composition more plausible.
help Kepler-10c FAQ
What is Kepler-10c?
Kepler-10c is a transiting exoplanet that orbits Kepler-10, a Sun-like star located in the constellation Draco. It was discovered using data gathered by NASA's Kepler space telescope.
Why was Kepler-10c initially called a "mega-Earth"?
After an early mass estimate near 17 Earth masses, scientists initially described it as a massive, potentially rocky "mega-Earth." This was highly unusual at the time, as most planets of that size are gaseous mini-Neptunes.
How big is the exoplanet Kepler-10c?
The planet has a radius of about 2.35 times that of Earth, making it significantly larger than our planet. Subsequent measurements revised its mass downward, leading to debates about its true composition.
What other planets are in the Kepler-10 system?
The star Kepler-10 is also known to host Kepler-10b, which was the first confirmed rocky planet found outside our solar system. Kepler-10c was the second planet discovered in this specific planetary system.
