About this world
MOA-2010-BLG-117L b is a gas giant orbiting MOA-2010-BLG-117L, a star 11.4 thousand light-years from Earth. It is about 1.3 times the size of Jupiter (its size estimated from its mass) and holds 0.53 Jupiter masses.
At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2018 by microlensing with MOA. A foreground star's gravity magnifies a background star; a planet adds a blip.
