About this world
OGLE-2018-BLG-1700L b is a gas giant orbiting OGLE-2018-BLG-1700L, a star 24.8 thousand light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass) and holds 4.4 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.
