Nomenclature

The designation WASP-62 indicates that this was the 62nd star found to have a planet by 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 South Africa. The approved names were announced in December 2019. The star is named Naledi, which means star in several languages of South Africa, and the planet is named Krotoa after a Khoi translator during colonial times.[7][8]

A transiting hot Jupiter exoplanet orbiting WASP-62 was discovered in 2012 by WASP-South[4] at the South African Astronomical Observatory.[9] The planet's equilibrium temperature is 1440±30 K, but the measured average temperature is colder at 1329.6±44.8 K.[10] In 2020, a transmission spectrum indicated the atmosphere of WASP-62b is free of clouds. It contains sodium and possibly silicon hydrides.[11]

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
°.[6]
