Characteristics
Mass and orbit
OGLE-2007-BLG-349L(AB)b is a super-Neptune, an exoplanet that has a mass and radius larger than that of Neptune. It has a mass of around 80 ME.[1] This is somewhat close to the mass of Saturn, 95 ME, so OGLE-2007-BLG-349L(AB)b can also be considered a gas giant. It orbits at a distance of around 2.9 AU in a circumbinary orbit, meaning it orbits around two stars.
Host star
The planet orbits in a circumbinary (
OGLE-2007-BLG-349L. They orbit around each other roughly every 9 days.[1] The stars have masses of 0.41 and 0.30 M☉, respectively. The age of the system, radii and temperatures of the stars are not known. In comparison, the Sun is 4.6 billion years old[4][5] and has a surface temperature of 5778 K.[6] The star's apparent magnitude
, or how bright it appears from Earth's perspective, is 14.3. Therefore, it is too dim to be seen with the naked eye.
