About this world
OGLE-2018-BLG-0677L b is a super-Earth orbiting OGLE-2018-BLG-0677L, a star 24.7 thousand light-years from Earth. It is about 1.8 times the size of Earth (its size estimated from its mass) and holds 4 Earth 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.
