eta Tel b
eta Tel b
eta Tel b is an exoplanet orbiting the star eta Tel, located about 161.6 light-years (49.5 pc) away from Solar System. Its discovery was publicly announced on 2024.
The host star eta Tel has apparent magnitude of 5.0, with absolute magnitude of 1.5. It is 2.1 times more massive and 1.6 times bigger compared with our Sun. The surface temperature is 9000 with its spectral types of A8V C
In this planetary system, the extrasolar planet eta Tel b orbits around the star eta Tel every 804000.0 days with its orbital distance of 218.00 AU ( 32612335812.6 km)
