KL Dra b
KL Dra b
KL Dra b is an exoplanet orbiting the star KL Dra, located about 2283.1 light-years (700.0 pc) away from Solar System. Its discovery was publicly announced on 2011.
The host star KL Dra has apparent magnitude of 22.0, with absolute magnitude of 12.8. It is 0.3 times more massive compared with our Sun. The surface temperature is 25000 with its spectral types of DB
In this planetary system, the extrasolar planet KL Dra b orbits around the star KL Dra every 0.0 days with its orbital distance of 0.00 AU ( 130150.1 km)
