Because of this, Cruithne and Earth appear to follow each other in their paths around the Sun. This is why Cruithne is sometimes called "Earth. Although no other moons of Earth have been found to date, there are various types of near-Earth objects in 1:1 resonance with it, which are known as quasi-satellites. Quasi-satellites orbit the Sun from the same distance as a planet, rather than the planet itself.
3753 Cruithne /kruːˈiːnjə/ kroo-EE-nyə or /ˈkrʊnjə/ KRUUN-yə is a Q-type, Aten asteroid in orbit around the Sun in 1:1 orbital resonance with Earth, making it a co-orbital object. It is an asteroid that, relative to Earth, orbits the Sun in a bean-shaped orbit that effectively describes a horseshoe, and that can transition into a quasi-satellite orbit. Cruithne does not orbit Earth. Could Earth's other 'moon' reveal the solar system's secrets? Cruithne's strange orbit may shed light on how planets evolve.

I think you're referring to quasi-satellites, of which there are several. These aren't true moons; they orbit the sun but have a 1:1 orbital resonance with the Earth that makes them seem that way. What this is referring to is an actual second moon, in orbit around the Earth, that existed for. Once it’s moved so far away it’s approaching Earth from the other side, it turns around and moves away again. Horseshoe orbits are actually quite common for moons in the solar system. Saturn has a couple of moons in this configuration, for instance. What’s unique about Cruithne is how it wobbles and sways along its horseshoe. Although the Moon is Earth's only natural satellite, there are a number of near-Earth objects NEOs with orbits that are in resonance with Earth. These have been called, inaccurately but provocatively, "second", "third" or "other" moons of Earth. Look up into the night sky and count the moons. You can see only one moon, “the” Moon.

In astronomy, a co-orbital configuration is a configuration of two or more astronomical objects such as asteroids, moons, or planets orbiting at the same, or very similar, distance from their primary, i.e. they are in a 1:1 mean-motion resonance. or 1:−1 if orbiting in opposite directions. There are several classes of co-orbital objects, depending on their point of libration. is an Aten asteroid in orbit around the Sun in 1:1 orbital resonance with Earth, making it a co-orbital object. It is a minor planet in solar orbit that, relative to Earth, orbits in a bean-shaped orbit that ultimately effectively describes a horseshoe, and which can transition into a quasi-satellite orbit. It has been incorrectly called "Earth's second moon". Cruithne does not orbit Earth and.
