TOI-3457 and Its Jupiter-Like Planet
TOI-3457 is a star 1210 light-years away with a mass of 1.04 solar masses and a radius of 1.47 solar radii. Its reported radius estimate is larger than the Sun's, and its temperature of 6300 K is hotter than the Sun's. One planet is known to orbit this host.
That planet, TOI-3457 b, is Jupiter-like, a size class for planets exceeding 4 times Earth's radius. It was found by transit, the dip in a star's brightness when a planet crosses in front of it from our viewpoint. Its radius of 10.6 Earth radii is larger than Earth's. The planet's mass is a reported upper limit of 797.74930157 Earth masses, and it completes an orbit every 32.6 days.
