MOA-2007-BLG-192L
The discovery of a planet, MOA-2007-BLG-192Lb, orbiting this object was announced on June 2, 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.
List of transiting exoplanets
The most massive transiting exoplanet is KELT-1b which masses 27.23 M (making it a brown dwarf) while the least massive is Kepler-42d which masses less than 0.003 M or 0.9 M. The largest exoplanet known is HAT-P-32b which is 2.037 R. The smallest exoplanet known is also Kepler-42d which is 0.051 R or 0.57 R. The densest transiting exoplanet known is COROT-3b, which has density of 26.4 g/cm; the diffusest transiting planet known is Kepler-12b, which has density of only 0.111 g/cm. The longest period of any transiting planets is Kepler-1647b, which takes 1107 days to orbit its (double) stars. The shortest period is Kepler-42c, which takes just 0.45 days to orbit its star
