Officially named 3I/ATLAS, the comet was confirmed as having originated outside of Earth's solar system on July 3, according to the European Space Agency (ESA) and NASA. It is believed to be about 20 kilometers, or over 12 miles wide, according to the ESA and traveling at about 60 kilometers, or 37 miles per second relative to the sun.

I/ATLAS, earlier known as A11pI3Z, is only the third interstellar visitor to be discovered passing through our corner of the galaxy.

Dubbed 3I/ATLAS, the comet poses no danger to Earth and will remain roughly 150 million miles away as it speeds by.
