Kepler-186 c – an Exoplanet

Kepler-186 c is an exoplanet that orbits the star Kepler-186, which are 579.1 light-years (177.6 pc) from our Solar System. It is an exoplanet that orbits a M-type star. Its discovery was made public in 2014. It has a mass of 2.1 Earths, takes 7.3 days to complete one orbit around its star, and is 0.0451 AU away from it. It was discovered in 2014 and was announced.

Kepler-186 is a main-sequence M1 dwarf star in the constellation Cygnus, located 178.5 parsecs (582 light years) away. The star is slightly cooler than the sun and has about half the metallicity. With a mass 0.544 times that of the Sun and a density of 5.29 g/cm3, the star is a M-type red dwarf on the verge of becoming a K-type orange dwarf. The five planets discovered in the vicinity of Kepler-186 are all expected to have solid surfaces. The smallest, Kepler-186b, is only 8% larger than Earth, while the largest, Kepler-186d, is nearly 40% larger.


Kepler-186 c is an extrasolar planet (exoplanet) that orbits the star Kepler 186 in the Cygnus constellation. Kepler-186 has an apparent magnitude of 12.5, and an absolute magnitude of 6.2. A planet that orbits a star other than the Sun is known as an exoplanet. It is 0.5 times more massive and 0.5 times larger than our Sun. According to the most recent parallax records, the star is 492.51 light years or 151.00 parsecs from Earth. The surface temperature is 3748 degrees Celsius, and the spectral type is M1. The extrasolar planet Kepler-186 c orbits the star Kepler-186 every 7.3 days at an orbital distance of 0.05 AU in this planetary system.

The Orbital Period, or the year of the planet, is 7.267302 days or 0.02 Earth Years. By the end of a full year, the Earth will have completed 50.22 orbits around its star. The semi-major axis is the point in the orbit that is farthest from the star. The Earth orbits the Sun with a semi-major axis of just over 1 A.U. The average distance between the Earth and the Sun is one A.U. The planet travels closer to its star than Mercury does to the Sun.
