KELT-17 b
KELT-17 b
KELT-17 b is an exoplanet orbiting the star KELT-17, located about 684.9 light-years (210.0 pc) away from Solar System. Its discovery was publicly announced on 2015.
The host star KELT-17 has apparent magnitude of 9.3, with absolute magnitude of 2.7. It is 1.6 times more massive and 1.6 times bigger compared with our Sun. The surface temperature is 7454 with its spectral types of A
In this planetary system, the extrasolar planet KELT-17 b orbits around the star KELT-17 every 3.1 days with its orbital distance of 0.05 AU ( 7301872.1 km)
(Projected orbit of KELT-17 b around its host star KELT-17)
