YSES 2 is a young, Sun-like star in the constellation of Musca. It is approximately 360 ly from Earth in the Scorpius-Centaurus Association. Its age is 14 million years.
The star was believed to be orbited by the exoplanet YSES 2 b, a super-jovian gas giant with times the mass of Jupiter that had an estimated separation of 114 AU. It was discovered through direct imaging by Bohn et al. in 2021, but in 2025 was determined to be a background star and not a planet.
