Earth has temporarily captured a second moon, asteroid 2024 PT5, turning it into a mini-moon. Detected by astronomers at Complutense University of Madrid using a telescope in South Africa, this event highlights the improved capability to spot such small celestial bodies. Mini-moons are asteroids temporarily captured by Earth’s gravity, usually orbiting the sun but occasionally pulled into Earth’s orbit. According to NASA, 2024 PT5’s stay will be brief.
