Quasi-moons are not real moons and don't actually orbit the Earth, although they sometimes appear to do so for short periods of time, Phil Nicholson, professor of astronomy at Cornell University, told ...

As mankind was planning the first moon landing in the 1960s, an asteroid approached Earth—and still hasn’t left.

The universe has quasi-moons, mini-moons, and moonlets, but no official definition of what counts as a moon.

Researchers are discussing 2025 PN7, a small celestial body that's following a similar orbital path to our planet's without ...

A small asteroid has been quietly following Earth’s orbit for decades—unseen, unbothered and, until recently, completely unknown. Astronomers have now confirmed the existence of 2025 PN7, a so-called ...

Astronomers have spotted a quasi-moon near Earth — and the small space rock has likely been hanging out near our planet unseen by telescopes for about 60 years, according to new research. The newly ...

This is a beautiful Lego space set, with approximate month and year positions of the earth's and moon's orbit around the sun and gives plenty of STEM stimulation at the same time. Size and distances ...
