24 Boo is a Sun-like G-type star (about 1.05 solar masses, 4,816 K, 12.2 solar radii), 96.0 light-years from Earth. 24 Boo b is a 0.88-Jupiter-mass companion, with an orbital period of 30.3 days, at 0.194 AU from its star, discovered in 2018 via radial velocity. The planet betrayed itself through the star's reflex motion — a technique that first revealed worlds around Sun-like stars in the 1990s and remains a workhorse of exoplanet discovery. 24 Boo b orbits well inside Earth's distance from the Sun.
