HIP 21152 and Its Lone Known Planet

HIP 21152 is a star 142 light-years from us with a spectral type of F5 V, placing it among the hotter, more massive F-class dwarfs. It is part of a system with two cataloged stars, though its stellar measurements describe the host alone: an age of 0.65 billion years, a mass of 1.4 solar masses, and a temperature of 6660 K. That mass is larger than the Sun's, and the star is likewise hotter than the Sun. One planet orbits this host.

That planet, HIP 21152 b, was discovered by imaging in 2022. Its mass is 7630 Earth masses, roughly 24 times Jupiter's mass and larger than Earth's. It completes an orbit in 22000 days.
