In 2014, the planet's parameters were observed. The paper states that KELT-6 has just entered the subgiant phase, and is no longer on the main sequence. In 2015, an additional planet, c, was discovered using the radial velocity method. Properties 
KELT-6b is a hot Saturn with 44.2% Jupiter's mass, but has been bloated to 1.3 times Jupiter's radius. It's density is half of Saturn's, and it has an equilibrium temperature of 1,313 K, but a hotter dayside temperature of 1,531 K.
