About this world
MOA-2016-BLG-526L b is a sub-Neptune orbiting MOA-2016-BLG-526L, a star 22.6 thousand light-years from Earth. It is about 4 times the size of Earth (its size estimated from its mass) and holds 15 Earth masses.
At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2024 by microlensing with MOA. A foreground star's gravity magnifies a background star; a planet adds a blip.
