The GJ 160.2 Exoplanetary System
GJ 160.2 is a star with 0.69 times the mass of the Sun, and 0.7849999999999999 times its radius. It is located 84.41 light years away from the solar system.
GJ 160.2 is known to have 1 exoplanets in orbit around it.
GJ 160.2 b
GJ 160.2 b was discovered by the Multiple Observatories observatory using the radial velocity method. Its discovery was announced in 2014-06. Its semi-major axis is 0.05 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 5.24 Earth days to complete an orbit around its host star, GJ 160.2.
Its eccentricity, the extent to which the shape of the exoplanet's orbit departs from a perfect circle (Earth's is 0.0167, which is why the shape of Earth's orbit is circular rather than oval in appearance), is 0.06, which means that when GJ 160.2 b is at is at its closest point to its host star, 0.05 astronomical units separates the two, and when it is at its farthest point, this number is 0.06. In the case of Earth, these numbers are 0.9832899 and 1.0167103 respectively.
The mass of GJ 160.2 b is 10.20 times the mass of Earth. At more than 10 Earth masses, GJ 160.2 b is an ice giant, a planet that is made up mostly of volatiles like water, amonia and methane, and enveloped by a dense hydrogen and helium atmosphere, much like Uranus and Neptune in our solar system.
