Physical properties
KELT-10 is a yellow dwarf very similar to the Sun, but 7% more massive and has 1.16 times the radius. It is also hotter, with a temperature of 5883 K, while the Sun has a temperature of 5778 K due to its spectral class. The (V) in spectral class, states that it is in the main sequence. The star is also slightly younger, with an age of 4.5 billion years.
Planetary systems
In 2015, a hot Jupiter was discovered by KELT.
