KELT-6b is anexoplanet orbiting theF-typesubgiantKELT-6 approximately 791light years away in the northernconstellationComa Berenices. It was discovered in 2013 using the transit method, and was announced in 2014.

In 2014, the planet's parameters were observed. The paper states that KELT-6 has just entered thesubgiant phase, and is no longer on themain sequence. In 2015, an additional planet,c, was discovered using theradial velocity method.^[4]

KELT-6b is ahot Saturn with 44.2%Jupiter's mass, but has been bloated to 1.3 timesJupiter's radius. Its density is half ofSaturn's, and it has anequilibrium temperature of 1,313K, but a hotter dayside temperature of 1,531 K.^[5]
