Astronomers have identified 2025 PN7, a small, faint asteroid, as a quasi-moon that has been orbiting near Earth for approximately 60 years. This celestial object, about the size of a city bus, follows the sun but stays in Earth's orbital path,

A new study reveals that the largest lunar crater, South Pole-Aitken basin, was formed by an oblique impact that shaped the far side.

The study explains that 2025 PN7 is currently in a 1:1 resonance with Earth, meaning it takes the same time to orbit the Sun as we do-about one year. That synchronized motion keeps it near Earth, but it's never gravitationally bound to our planet like the moon is.
