YanYan
{
Yanyan, originally named HD 38283 b, is an extrasolar planet, orbiting the 7th magnitude F-type main-sequence star Bubup, 123 light years away in the constellation Mensa. It is a Saturn-like planet orbiting at Earth-like distance, though slightly inwards of its star's habitable zone. Its eccentricity is 0.41, much higher than the Earth's eccentricity of 0.017. The planet's distance ranges from about 0.60 AU (closer to its star than Venus is to the Sun) and 1.44 AU (nearly as distant from its star as Mars is to the Sun). This planet takes 363.2 days to orbit the star, just two days less compared to the Earth's orbital period of 365.256366 days. Its mass is one-third that of Jupiter but its size and density are not known. Since inclination is not known, its actual mass is unknown, either slightly greater or much greater than its lower limit.
This planet could have Earth-like moons with bodies of water and possible life due to the planet's similar distance from its parent star as Earth. But, given the planet's high eccentricity, and the star being more than twice as luminous as the Sun, hypothetical life on the moons may be a bit unlikely.
