WASP-64
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.
Nomenclature
The designation WASP-64 comes from the Wide Angle Search for Planets.This was one of the systems selected to be named in the 2019 NameExoWorlds campaign during the 100th anniversary of the IAU, which assigned each country a star and planet to be named. This system was assigned to Togo. The approved names were Atakoraka for the star after the Atacora, the largest mountain range in Togo, and Agouto for the planet after Mount Agou, the highest mountain in Togo.
