WASP-62, formally named Naledi, is a single star about {{convert|573|ly|pc|lk=on|abbr=off}} 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, and it has a metal abundance similar to the Sun.
Nomenclature
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.
Planetary system
A transiting hot Jupiter exoplanet orbiting WASP-62 was discovered by WASP in 2012. The planet's equilibrium temperature is 1440{{±|30}} K, but the measured average temperature is colder at 1329.6{{±|44.8}} K. In 2020, a transmission spectrum indicated the atmosphere of WASP-62b is free of clouds. It contains sodium and possibly silicon hydrides.{{citation|arxiv=2011.06424|title=Evidence of a Clear Atmosphere for WASP-62b: The Only Known Transiting Gas Giant in the JWST Continuous Viewing Zone|year=2021|last1=Alam|first1=Munazza K.|last2=Lopez-Morales|first2=Mercedes|last3=MacDonald|first3=Ryan J.|last4=Nikolov|first4=Nikolay|last5=Kirk|first5=James|last6=Goyal|first6=Jayesh M.|last7=Sing|first7=David K.|last8=Wakeford|first8=Hannah R.|last9=Rathcke|first9=Alexander D.|last10=Deming|first10=Drake L.|last11=Sanz-Forcada|first11=Jorge|last12=Lewis|first12=Nikole K.|last13=Barstow|first13=Joanna K.|last14=Mikal-Evans|first14=Thomas|last15=Buchhave|first15=Lars A.|journal=The Astrophysical Journal|volume=906|issue=2|pages=L10|doi=10.3847/2041-8213/abd18e|bibcode=2021ApJ...906L..10A |s2cid=226306572 |doi-access=free }}
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}}°.
