About this world
OGLE-2016-BLG-0613L AB b is a gas giant orbiting OGLE-2016-BLG-0613L AB, a star 11.1 thousand light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass) and holds 4.2 Jupiter masses.
At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2017 by microlensing with OGLE. A foreground star's gravity magnifies a background star; a planet adds a blip.
