An Arjuna asteroid, discovered in August, will become a "mini-moon" event for nearly two months from Sept. 29 to Nov. 25.

An asteroid is approaching the Earth which the experts say will come close enough to be caught in our planet’s gravity well, technically becoming a second moon, at least for a few months. University of Iowa physics and astronomy Professor Casey DeRoo says this asteroid will be captured by the Earth’s gravitational pull around September

Starting next week, the moon, Earth’s closest celestial body, will be joined by a new neighbor: a second moon. From Sept. 29 until Nov. 25, astronomers calculate that 2024 PT5— which is what scientists think is an asteroid but have dubbed a “mini-moon”—will be looping around Earth.
