About this world
OGLE-2006-BLG-109L c is a gas giant orbiting OGLE-2006-BLG-109L, a star 4.92 thousand light-years from Earth. It is about 0.99 times the size of Jupiter (its size estimated from its mass) and holds 0.27 Jupiter masses. It completes an orbit every 13.5 years at 4.5 AU from its star.
Its equilibrium temperature is about 59 K (−214 °C): too cold for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2008 by microlensing with OGLE. A foreground star's gravity magnifies a background star; a planet adds a blip. OGLE-2006-BLG-109L has 2 known planets; the others are OGLE-2006-BLG-109L b.
