GD 552 b
GD 552 b
GD 552 b is an exoplanet orbiting the star GD 552, located about 342.5 light-years (105.0 pc) away from Solar System. Its discovery was publicly announced on 2008.
The host star GD 552 has apparent magnitude of 16.5, with absolute magnitude of 11.4. It is 0.6 times more massive compared with our Sun. The surface temperature is 10900 with its spectral types of DN
In this planetary system, the extrasolar planet GD 552 b orbits around the star GD 552 every 0.1 days with its orbital distance of 0.00 AU ( 430841.9 km)
(Projected orbit of GD 552 b around its host star GD 552)
The Star GD 552 's habitable zone is located at the following distance
