The Earth often gets a few visitors in the solar system, but some stick around for a while. Here's what to know about the 'quasi-moon.'

Interest in the moon has been high—just in the past two years there have been 12 attempts to send missions to the moon, nearly half of which private companies undertook. With so much activity, it's important to start thinking about coordination and safety.

A view of what's known as the Cold Moon in December of 2023. The 2025 Cold Moon will rise on Dec. 4, according to the Old Farmer's Almanac. You don't need any special equipment to see the next full moon.

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

Scientists have discovered asteroid 2025 PN7, a celestial body now identified as a quasi-satellite. This asteroid will orbit Earth's path for about 50 years. Unlike our Moon, it is not gravitationally bound to our planet.

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 ABC News. Instead, they orbit the sun -- like typical asteroids -- on paths that are "very similar" to Earth's.

The biggest and brightest full moon of 2025 is coming up soon. November's Beaver Moo n will not only be a supermoon, but it will be the biggest supermoon of the year. It's the biggest moon because it will be at its nearest point to the Earth, 221,817 miles away.

The full moon of November, called the Beaver Moon, will be full illuminated on Nov. 5 at 8:19 a.m. Eastern Time (1319 GMT), according to the U.S. Naval Observatory. This moon will also be a " supermoon ,
