An SUV-size space rock flew past our planet over the weekend and was detected by a NASA-funded asteroid survey as it departed.

PASADENA, Calif. (NASA PR) — Near Earth Asteroids, or NEAs, pass by our home planet all the time. But an SUV-size asteroid set the record this past weekend for coming closer to Earth than any other known NEA: It passed 1,830 miles (2,950 kilometers) above the southern Indian Ocean on Sunday, Aug. 16 at 12:08 a.m. EDT (Saturday, Aug. 15 at 9:08 p.m. PDT).

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