XO-4 b
XO-4 b
XO-4 b is an exoplanet orbiting the star XO-4, located about 840.6 light-years (257.7 pc) away from Solar System. Its discovery was publicly announced on 2008.
The host star XO-4 has apparent magnitude of 10.7, with absolute magnitude of 3.6. It is 1.3 times more massive and 1.6 times bigger compared with our Sun. The surface temperature is 5700 with its spectral types of F5V
In this planetary system, the extrasolar planet XO-4 b orbits around the star XO-4 every 4.1 days with its orbital distance of 0.05 AU ( 8205443.2 km)
(Projected orbit of XO-4 b around its host star XO-4)
The Star XO-4 's habitable zone is located at the following distance
