HAT-P-5 is a 12th magnitude star in the constellation Lyra, approximately 1,000 light years away from Earth. It is a spectral type G star, about 1.16 solar masses and radii greater than the Sun, and only 200 kelvins hotter. It is estimated to be 2.6 billion years old.[7][8]
The star HAT-P-5 is named Chasoň. The name was selected in the NameExoWorlds campaign by Slovakia, during the 100th anniversary of the IAU. Chasoň is an ancient Slovak term for the Sun.[9][10]
Planetary system
On October 9, 2007, a report was submitted to The Astrophysical Journal Letters telling of the discovery of an exoplanet transiting HAT-P-5. The planet was described as a Jupiter-like hot Jupiter, with a radius about one and one quarter times that of Jupiter, and nearly the same mass. Its density was reported as 0.66 ± 0.11 g/cm3, and its inclination 86.75 ± 0.44°.[3]
