MOA-2007-BLG-192L is a low-mass red dwarf star or brown dwarf, approximately 3,000 light-years away in the constellation of Sagittarius. It is estimated to have a mass approximately 6% of the Sun's. In 2008, an Earth-sized extrasolar planet was announced to be orbiting this object.

Planetary system

The discovery of a planet, MOA-2007-BLG-192Lb, orbiting this object was announced on June 2, 2008. [http://www.nd.edu/~bennett/moa07blg192/ MOA-2007-BLG-192Lb: A Low-Mass Planet with a Possible Sub-Stellar-Mass Host] , David P. Bennett. Accessed on line July 3, 2008.] This planet, with a mass of approximately 3.3 times that of Earth, is one of the smallest known extrasolar planets. It was found when it caused a gravitational microlensing event on the night of May 24, 2007, which was detected as part of the MOA-II gravitational microlensing survey at the Mount John University Observatory in New Zealand.
