OGLE-2006-BLG-109Lc

OGLE-2006-BLG-109Lc is an extrasolar planet approximately 4,925 light-years away^[1] in the constellation of Sagittarius. The planet was detected orbiting the star OGLE-2006-BLG-109L in 2008 by a research team using Microlensing. The host star is about 50% the mass of the Sun and the planet is about 90% the mass of Saturn.^[2][3]
