KELT-17 is a single star located 739 light-years away. Its spectral type is A, and the star has an age of 0.65 billion years, a mass of 1.64 solar masses, a radius of 1.65 solar radii, and a temperature of 7450 K. The star's reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet is known to orbit KELT-17.
That planet is KELT-17 b, a Jupiter-like world discovered by transit in 2016 and completing an orbit in 3.08 days. Its radius is 17.1 Earth radii, larger than Earth's, and its mass is 416 Earth masses, also larger than Earth's and roughly 1.31 times Jupiter's mass. Its mean density is 0.459 g/cm³, 0.0834 times Earth's.
