KELT-1 and Its Jupiter-like Planet

KELT-1 is a star 876 light-years away with one known planet. The star's reported mass estimate is larger than the Sun's, at 1.34 solar masses, and its reported radius estimate is also larger than the Sun's, at 1.47 solar radii. Its reported temperature is hotter than the Sun's, at 6520 K.

The planet KELT-1 b is a Jupiter-like world, meaning its radius exceeds four times Earth's. Its radius of 12.4 Earth radii is larger than Earth's, and its mass of 8650 Earth masses is larger than Earth's as well, roughly 27.2 times Jupiter's mass. It completes an orbit in 1.22 days, a period established through transit observations, in which the planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Its mean density is 24.8 g/cm³, 4.49 times Earth's.
