Astronomers are tracking a newly spotted comet hailing from parts unknown, only the third time such an interstellar object has been observed visiting our solar system.

The object — thought to be a comet — is only the third-ever confirmed interstellar visitor to pass through our cosmic neighborhood. Dubbed 3I/ATLAS, the comet poses no danger to Earth and will remain roughly 150 million miles away as it speeds by, according to NASA.
