- Planetary Defenses MISSED Asteroid Flyby That Came Within 400km of Earth on Friday 13th

A disturbing new record for the closest asteroid flyby of the Earth has been set, after a space rock named 2020 VT4 came within 400 kilometers (250 miles) of the planet on Friday the 13th. And our planetary defenses missed it.
–
The asteroid was spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at the Mauna Loa Observatory in Hawaii some 15 hours after it made its close approach from our sun-facing blind spot.

Estimated to measure between five and 10 meters (16-32 feet) in diameter (about 5.5 refrigerators stacked on top of one another), 2020 VT4 made its closest approach at 17:20 Universal Time (UT) on Friday November 13 over the South Pacific, near the Pitcairn Islands.

Newly-discovered asteroid A10sHcN approached Earth yesterday, passing only a few hundred miles above the South Pacific Ocean. This encounter shortened its orbit, ensuring that this Earth-crosser will make more frequent close approaches.https://t.co/TmkzojIzPf pic.twitter.com/XrnKiiGTyJ
