Didn’t I say that it could happen at anytime and we might not even see it coming?
Well, last Friday the 13th (11/13/20),asteroid 2020 VT set a new record for the closest asteroid near-miss. It zipped past Earth at just 240 miles above our heads. For reference the ISS Space station orbits 250 miles up. Oh…and we discovered it after it passed.
Luckily 2020 VT is only about 20-30 feet in diameter so if it did fly into our atmosphere it likely would have just been a bright fireball in the sky as it burned up.
Keep your aluminum foil hats handy! The next one could be bigger and not miss!

From Universe Today: Wow. A low-flying space rock set a record last Friday (appropriately, the 13th), when 2020 VT4 passed just under 400 kilometers (250 miles) over the Southern Pacific.
The asteroid was spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at the Mauna Loa Observatory in Hawaii in the early morning hours of Saturday, November 14th, just 15 hours after approach. This is not uncommon for fast-movers, especially asteroids that are coming at the Earth from our sunward blind-spot, like 2020 VT4.
The asteroid- 2020 VT4 is estimated to be 5-10 meters (16-32 feet) across, about the size of a small house. Earth juuust missed occupying the same space as the perihelion point for the asteroid, which occurred just 20 hours prior to Earth passage.
This sets a record for the closest documented non-meteoric asteroid pass versus the Earth. This record was already broken once this year, with the passage of asteroid 2020 QG 3,000 kilometers (1,864 miles) from the surface of the Earth on August 16th. A brilliant bolide was captured on video on the afternoon of August 10th, 1972, as it became a brilliant daytime fireball over the Grand Teton Mountains in Wyoming before skipping back out of the Earth’s atmosphere. Another recent record was set in October 2008, when astronomers spotted 4-meter (13 foot) asteroid 2008 TC3 19 hours prior to impact,and later recovered fragments in the Nubian Desert in northern Sudan two months later, making 2008 TC3 the first asteroid that was documented before and after impact.
Unfortunately, the close passage of asteroid 2020 VT4 seems to have gone unwitnessed; closest approach occurred at 17:20 Universal Time (UT) on Friday November 13th over the South Pacific near the Pitcairn Islands under daytime skies, and it followed the edge of the Earth’s shadow outbound. For context, the International Space Station also orbits 400 kilometers (250 miles) above the surface of the Earth, and is 109 meters (358 feet) from tip-to-tip… 2020 VT4 would have certainly been visible as a fast-moving +3 magnitude ‘star’ on its out-bound leg south of Tasmania in the pre-dawn sky, had any island-bound observer or early morning sailor happened to be watching.…
