Atakoraka
Sign in to saveWASP-64, also named Atakoraka, is a star about 1,177 light-years away in the constellation Canis Major. It is a G7 class main-sequence star, orbited by a planet WASP-64b. It is younger than the Sun at 3.6 billion years, and it has a metal abundance similar to the Sun. The star is rotating rapidly, being spun up by the giant planet in a close orbit.

WASP-64, also named Atakoraka, is a star about 1,177 light-years away in the constellation Canis Major. It is a G7 class main-sequence star, orbited by a planet WASP-64b. It is younger than the Sun at 3.6 billion years, and it has a metal abundance similar to the Sun. The star is rotating rapidly, being spun up by the giant planet in a close orbit.
While an imaging survey in 2017 failed to find any stellar companions, a 2019 survey using Gaia DR2 data found WASP-64 to be the secondary component of a double star system, with a wide separation of 24.2 arcseconds or 9,058 AU. The primary star is designated TYC 7091-1288-1, and can also be called WASP-64 A, with the planet host being WASP-64 B. Although the stars share a similar distance and common proper motion, their relative space velocity appears to be high enough that the pair are not gravitationally bound.
