Almost a year ago, the space science community watched as an asteroid entered Earth's orbit and circled above our heads for almost two months before departing. Scientists usually track such asteroids ...

Astronomers have re-discovered a temporary moon that has joined Earth’s orbit. The mini-moon/asteroid is named 2025 PN7. It’s about 62 feet in diameter and will eventually return to its other orbital ...

Asteroid 2022 RD2 is a near-Earth object that could become a temporary moon, then later a potential crash risk for the planet later this century. - NASA / JPL-Caltech illustration Scientists have ...

When you think of moons orbiting around celestial bodies, the first that naturally springs to mind is Earth's own moon. Certainly, that moon is ours – it is firmly locked within orbit around our ...
