EF Eri b
EF Eri b
EF Eri b is an exoplanet orbiting the star EF Eri, located about 362.0 light-years (111.0 pc) away from Solar System. Its discovery was publicly announced on 2000.
The host star EF Eri has apparent magnitude of 14.5, with absolute magnitude of 9.3. It is 0.9 times more massive compared with our Sun. The surface temperature is 10000 with its spectral types of DA
In this planetary system, the extrasolar planet EF Eri b orbits around the star EF Eri every 0.1 days with its orbital distance of 0.00 AU ( 418874.0 km)
