Possible “mini-moon” orbiting Earth spotted by Tucson astronomers – ABC15 Arizona

TUCSON, AZ — Tucson astronomers have identified a doable “mini-moon” orbiting Earth!

On February 15, Astronomers Kacper Wierzchos and Theodore Pruyne noticed and started to monitor an asteroid that is caught in Earth’s orbit, and has been orbiting our world for an believed two to a few years.

“These occasions are seriously scarce,” stated Wierzchos, and astronomer at Cataline Sky Study in Tucson. “This is perhaps the second, maybe the 3rd asteroid out of a person million recognised that has entered the orbit of Earth.”

Wierzchos claimed there is however a probability that the “mini-moon” is a guy-produced item, but all indications place to the truth that this is a natural object. The “mini-moon” is deemed smaller and is frequently compared to the measurement of a car.

“We in all probability capture and eliminate these little tiny factors all the time,” said Patrick Youthful, Affiliate professor of Astrophysics at Arizona Point out College. “The reality that we control to see these types of a small point is quite extraordinary.”

The “mini-moon” will only be close to for a small even though for a longer time. Wierzchos claimed its trajectory will shoot it back out into house subsequent month.
