WASP-17 is an F-type main sequence star approximately 1,310 light-years away in the constellation Scorpius.
The name was selected in the NameExoWorlds campaign by Costa Rica, during the 100th anniversary of the IAU.
[6][7] The star, although similar to Sun in terms of overall contents of heavy elements, is depleted of carbon.
The star is unusual in that it has an orbiting exoplanet, WASP-17b,[9][10] which is believed to orbit in the opposite direction to the star's spin and is said to be twice the size of Jupiter, but half its mass.
It is subject to intensive photo-evaporation, and may be completely destroyed within one billion years from now.
