The video illustrates what a horseshoe orbit looks like, specifically for Cruithne orbiting around Earth. This is something not widely known, but this type of orbit is actually pretty common in our solar system. Cruithne's orbit is so wide, that its sometimes goes into the neighborhood of Venus and Mars. It orbits the sun about once a year, but it takes nearly 800 years to complete this messy ring shape around Earth's orbit.
Even though Cruithne could technically be considered Earth's second moon, there isn't too much information about what it's like on surface. It's only approximately five kilometers across, the surface gravity is very weak. Walking briskly is probably enough to send you strolling out into outer space.
Even though Cruithne is small, if it were to strike Earth, it would be an extinction-level event, similar to what is believed to have happened at the end of the Cretaceous period. However, it's not going to hit us any time soon. It's orbit is tilted out of the plane of the solar system, and astrophysicists have provided simulations confirming that it will not come anywhere near us anytime soon.
Elisa Quintana of the Search for Extraterrestrial Intelligence Institute at NASA stated:
"This is the first definitive Earth-sized planet found in the habitable zone.
Finding such planets is a primary goal of the Kepler space telescope."
The institute stated:
"This discovery not only proves the existence of worlds that might be similar to our own, but will undoubtedly shape future investigations of exoplanets that could have terrestial surface environments."
