Earth has caught a 'second moon,' scientists say
Asteroid 2024 PTS, which usually orbits the Sun as part of a small asteroid belt that follows Earth, should now be orbiting Earth as a second moon. The mini-moon event will end on November 25. These gravitational capture events are quite common. 2024 PTS won't be observable to the average skywatcher. After its brief stay around Earth, the asteroid will continue to orbit the sun as part of the Arjuna family of asteroids.
