YSES 2b is a red dwarf star located in the constellation of Musca.[2] It was discovered through direct imaging by Bohn et al. in 2021.[2][3] It was initially suspected to be a long-period planet, but in 2025 it was found to be a background star unrelated to YSES 2, a young, Sun-like star which is approximately 360 ly from Earth in Scorpius-Centaurus Association whose age is 14 million years.[4][1]
