The asteroid is named 2024 PT5 and is around 10-11 m (33-37 ft) in diameter. "Mini-moon" is apparently a class of asteroids that get caught up in Earth's gravity and have tempory unstable orbits until they finally get knocked away from Earth and continue on their journey through space. Mini-moons have orbits lasting a few days to around 2 years.
