PASADENA, Calif. (NASA PR) — A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system. The object — designated C/2019 Q4 (Borisov) — was discovered on Aug. 30, 2019, by Gennady Borisov at the MARGO observatory in Nauchnij, Crimea.

The first, ‘Oumuamua, was observed and confirmed in October 2017.
