A near-Earth object was likely ejected into space after an impact thousands of years ago. Now it could contribute new insights to asteroid and lunar science.

Last year, astronomers on the hunt for potentially dangerous near-Earth asteroids spotted something unusual. A space rock, now dubbed 2024 PT5 made several close passes by Earth, not quite orbiting our planet,

For a brief, but exciting, time last year, Earth had two moons. A small asteroid lingered close to our planet in its orbit around the Sun, temporarily caught by Earth’s gravity to become a far away mini-moon. A closer look at the space rock reveals a rather familiar origin: Earth’s mini-moon might actually be a broken-off piece of our regular Moon.

Typically, asteroids - like the one depicted in this artist's concept - originate from the main asteroid belt between the orbits of Mars

NASA's Jet Propulsion Laboratory monitors asteroid 2022 CE2, expected to safely pass Earth on January 16, 2025. The 370-foot-wide asteroid will come w
