How Many Moons Does Earth Have? One More, Now. Kinda.

Earth’s other ‘moon’ and its crazy orbit could reveal mysteries of the solar system by The Watcher 2/25/15 What you might not know is that the moon is not the Earth’s only natural satellite. As recently as 1997, we discovered that another body, 3753 Cruithne, is what’s called a quasi-orbital satellite of Earth..

3753 Cruithne in 2001. Astronomer Duncan Waldron discovered this faint asteroid on October 10, 1986, on a photographic plate taken with the UK Schmidt Telescope at Siding Spring Observatory in Australia.

3753 Cruithne - The other MoonAs recently as 1997, we discovered that another body, 3753 Cruithne, is what’s called a quasi-orbital satellite  of Earth. This simply means that Cruithne doesn’t loop around the Earth  in a nice ellipse in the same way as the moon, or indeed the artificial  satellites we loft into orbit. Instead, Cruithne scuttles around the  inner solar system in what’s called a “horseshoe” orbit.

(3753) Cruithne est un astéroïde géocroiseur d'environ 5 kilomètres de diamètre. Son orbite liée à celle de la Terre l'a parfois fait surnommer « seconde lune de la Terre » bien qu'il ne soit pas un satellite de celle-ci mais plutôt un « compagnon ».   Cruithne fait environ 5 kilomètres de diamètre. Il est situé sur une orbite elliptique normale autour du Soleil, avec une période orbitale quasiment égale à celle de la Terre. Cruithne parcourt son orbite elliptique en un peu moins d'un an…

Asteroid-3753-cruithne

Earth's other 'moon' could reveal mysteries of the solar system

Asteroid-3753-cruithne

3753 Cruithne A year on this asteroid (364 days) is almost exactly the same as a year on Earth, meaning they both orbit the sun at about the same distance. Nobody knew about our orbit-twin until 1986, when Duncan Waldron discovered it.  But don’t worry about a collision: Cruithne won’t come closer than 7.5 million miles from Earth.
