WASP-62, formally named Naledi, is a single star about 573 light-years (176 parsecs) away. It is an F class main-sequence star, orbited by a planet, WASP-62b. The age of WASP-62 is much younger than the Sun at 0.8±0.6 billion years,[4] and it has a metal abundance similar to the Sun.
Nomenclature
[edit]The designation WASP-62 indicates that this was the 62nd star found to have a planet by the Wide Angle Search for Planets.
In December 2019, WASP-62 was named Naledi and its planet was named Krotoa by amateur astronomers from South Africa as part of the second NameExoWorlds campaign.[5][6]
Planetary system
[edit]A transiting hot Jupiter exoplanet orbiting WASP-62 was discovered by WASP in 2012.[7] The planet's equilibrium temperature is 1440±30 K, but the measured average temperature is colder at 1329.6±44.8 K.[8] In 2020, a transmission spectrum indicated the atmosphere of WASP-62b is free of clouds. It contains sodium and possibly silicon hydrides.[9]
The planetary orbit is slightly misaligned to the equatorial plane of the star, with the misalignment angle equal to 19.4+5.1
−4.9°.[4]
