rho Ind b
rho Ind b
rho Ind b is an exoplanet orbiting the star rho Ind, located about 86.4 light-years (26.5 pc) away from Solar System. Its discovery was publicly announced on 2002.
The host star rho Ind has apparent magnitude of 6.1, with absolute magnitude of 3.9. It is 1.1 times more massive and 1.1 times bigger compared with our Sun. The surface temperature is 5636 with its spectral types of G4 IV-V
In this planetary system, the extrasolar planet rho Ind b orbits around the star rho Ind every 1256.0 days with its orbital distance of 2.32 AU ( 347067060.0 km)
