HD 38283 B
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.
History and discovery
Yanyan was discovered on 11 April 2011 using the radial velocity technique using the Anglo-Australian Telescope (AAT), and assigned the name HD 38283 b. This method uses to look for planets by watching the star periodically wobble caused by the gravitational tug of the orbiting planets.
The planet was officially named Yanyan by representatives of Australia in the 2019 NameExoWorlds contest held by the IAU. The word "Yanyan" is the Boonwurrung word for "boy".
