iot Dra b
iot Dra b
iot Dra b is an exoplanet orbiting the star iot Dra, located about 102.7 light-years (31.5 pc) away from Solar System. Its discovery was publicly announced on 2002.
The host star iot Dra has apparent magnitude of 3.3, with absolute magnitude of 0.8. It is 1.4 times more massive and 12.8 times bigger compared with our Sun. The surface temperature is 4445 with its spectral types of K2 III
In this planetary system, the extrasolar planet iot Dra b orbits around the star iot Dra every 510.9 days with its orbital distance of 1.45 AU ( 216617716.8 km)
