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

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

The comet is the third known interstellar object to pass through our solar system and is expected to make its closest approach to the sun in late October
