    "Earth Acquires a Minimoon" - Earth usually has more than one moon, according to a team of astronomers from the University of Helsinki, the Paris Observatory and the University of Hawaii at Manoa.

      "Earth Has Just One Moon, Right? Think Again. Tiny minimoons, just a few feet across, regularly make orbits around our planet." Cool!

    • Brienne Calmer

      Small asteroids temporarily in orbit around the earth are being called 'minimoons'. If they're not big enough to be moons, maybe we should just call them all Pluto.

      Top 10 Out of this World (Literally) Facts about Space - While the moon is indeed the only celestial body to observe a strict orbit of the Earth, there are in fact a number of other ‘near-Earth’ asteroids which follow the Earth as it orbits the Sun.

      The 'minimoons' are only a few feet across, and each tends to do a stint of around a year in orbit - before resuming their previous lives as asteroids

      “minimoons,” are thought to be only a few feet across and to usually orbit our planet for less than a year before resuming their previous lives as asteroids orbiting the Sun

      Mini-moons? "At any time, there are one or two 1-meter diameter asteroids in orbit around the Earth," says Robert Jedicke, an astronomer at the Institute for Astronomy at the University of Hawaii.

      Earth captures a minimoon. The path of a simulated minimoon that is temporarily captured by Earth. Inset: Radar image of near-Earth asteroid 1999 JM8. Minimoons are captured from the much larger population of near-Earth asteroids that pass close to Earth. This two-mile-diameter asteroid is more than a thousand times larger than the biggest minimoons, but it shows the irregular shape and pockmarked surface expected on the much smaller minimoons.

    A tiny second moon may once have orbited Earth before catastrophically slamming into the other one, a titanic clash that could explain why the two sides of the surviving lunar satellite are so different from each other, a new study suggests. "It is entirely plausible for a Trojan moon to have formed in the giant impact, and for it to go unstable after 10 million to 100 million years and leave its imprint on the moon," study coauthor Erik Asphaug, a planetary scientist at the University of Cal...
