WASP-63 or Kosjenka, also known as CD-38 2551, is a single star with an exoplanetary companion in the southern constellation of Columba.
[2] The distance to this system is approximately 942 light-years (289 parsecs) based on parallax measurements, but it is drifting closer with a radial velocity of −24 km/s.
WASP-63 is slightly enriched in heavy elements, having 120% of the solar abundance of iron.
[5] In 2012 a transiting gas giant planet WASP-63b was detected on a tight, circular orbit.
The planetary atmosphere contains water and likely has a high cloud deck of indeterminate composition.
