The NGC 2682 Sand 364 Exoplanetary System
NGC 2682 Sand 364 is a star with 9.06 times the mass of the Sun, and 39.59 times its radius. It is located 2730.02 light years away from the solar system.
NGC 2682 Sand 364 is known to have 1 exoplanets in orbit around it.
NGC 2682 Sand 364 b
NGC 2682 Sand 364 b was discovered by the Multiple Observatories observatory using the radial velocity method. Its discovery was announced in 2014-01. Its semi-major axis is 0.53 astronomical units, as compared to Earth's which is 1 astronomical unit. It takes 121.71 Earth days to complete an orbit around its host star, NGC 2682 Sand 364.
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 0.35, which means that when NGC 2682 Sand 364 b is at is at its closest point to its host star, 0.34 astronomical units separates the two, and when it is at its farthest point, this number is 0.72. In the case of Earth, these numbers are 0.9832899 and 1.0167103 respectively.
The mass of NGC 2682 Sand 364 b is 2126.15 times the mass of Earth. At more than 50 Earth masses, NGC 2682 Sand 364 b is a gas giant, a planet whose mass is mostly made up of hydrogen and helium, like Jupiter and Saturn in our solar system.
