About this world
K2-2016-BLG-0005L b is a gas giant orbiting K2-2016-BLG-0005L, a star 17 thousand light-years from Earth. It is about 1.2 times the size of Jupiter (its size estimated from its mass) and holds 1.1 Jupiter masses. It completes an orbit every 12.9 years at 4.2 AU from its star.
At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2023 by microlensing with K2. A foreground star's gravity magnifies a background star; a planet adds a blip.
