KELT-10, also known as CD−47°12635, is a sun-like star in the southern constellation Telescopium. It has an apparent magnitude of 10.62,[2] making it readily visible in telescopes, but not to the naked eye. Parallax measurements from the Gaia spacecraft place the star at a distance of 617 light years;[1] it is currently receding with a radial velocity of 31.6 km/s.[4]

KELT-10 has a stellar classification of G0 V,[3] indicating that it is a yellow dwarf like the Sun. However, the object is 7% more massive[5] and 21% larger.[3] It is also slightly hotter, with an effective temperature of 5,948 K[3] compared to the Sun's of 5,778 K. The star has a similar age, with an age of 4.5 billion years[3] and more luminous, having a luminosity 40% greater.[4] KELT-10's iron abundance is 123% that of the Sun,[3] consistent with a planetary host. However, this amount is poorly constrained.
