Physical Properties
KELT-10 is a yellow dwarf very similar to the Sun, but 7% more massive and 19% larger. It is also hotter, with a temperature of 5883 K, while the Sun has a temperature of 5778 K. The (V) in its spectral class, shows that it is in the main sequence. The star is also slightly younger than the Sun, with an age of 4.5 billion years and more luminous, having a luminosity 40% greater. KELT-10 hosts a planet and has 23% more heavy metals than the Sun.
Planetary System
In 2015, a "hot Jupiter" orbiting the star was discovered by the KELT-South telescope. KELT-10b orbits at a distance 10 time closer than Mercury orbits the Sun, and is bloated due to its orbit.
