About this world
OGLE-2015-BLG-1771L b is a gas giant orbiting OGLE-2015-BLG-1771L, a star 23.1 thousand light-years from Earth. It is about 1.3 times the size of Jupiter (its size estimated from its mass) and holds 0.43 Jupiter masses.
At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2020 by microlensing with OGLE. A foreground star's gravity magnifies a background star; a planet adds a blip.
