Yep, Earth will temporarily get a second moon. It’s called 2024 PT5 and it’s been called a “mini moon” by astronomers. 2024 PT5 is expected to join Earth’s orbit for two months, before breaking free sometime in November, according to research published earlier this month.

Approaching Earth at close range and at a low relative velocity, it will go into orbit on Sept. 29 and depart on Nov. 25, when it returns to orbiting the sun. It will also come very close to Earth on Jan.
