mu Ara d
mu Ara d
mu Ara d is an exoplanet orbiting the star mu Ara, located about 50.6 light-years (15.5 pc) away from Solar System. Its discovery was publicly announced on 2004.
The host star mu Ara has apparent magnitude of 5.2, with absolute magnitude of 4.2. It is 1.1 times more massive and 1.2 times bigger compared with our Sun. The surface temperature is 5700 with its spectral types of G3 IV-V
In this planetary system, the extrasolar planet mu Ara d orbits around the star mu Ara every 310.6 days with its orbital distance of 0.92 AU ( 137779638.9 km)
