NASA has discovered an interstellar comet that’s wandered into our backyard.The space agency spotted the quick-moving object with the sky-surveying Atlas telescope in Chile earlier this week, and confirmed it was a comet from another star 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.
