A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system.
The object is designated C/2019 Q4 (Borisov), and was discovered on Aug. 30, 2019, by Gennady Borisov at the MARGO observatory in Nauchnij, Crimea.
The official confirmation that comet C/2019 Q4 is an interstellar comet has not yet been made, but if it is interstellar, it would be only the second such object detected.
