About this world
EPIC 246851721 b is a gas giant orbiting EPIC 246851721, a yellow-white F-type star (type F5V) 1.22 thousand light-years from Earth. It is about 1.1 times the size of Jupiter and holds 3 Jupiter masses. It completes an orbit every 6.18 days at 0.072 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 1,401 K (1,128 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2018 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction.
