Closer than weather sats: Asteroid only discovered 5 DAYS ago whizzes by Earth in latest close call
An asteroid discovered only last Friday is expected to graze Earth this week, coming closer than most TV and weather satellites, in yet another reminder of the potential threats from incoming space rocks.
Asteroid 2020 SW was first spotted on September 18 by the Mount Lemmon Survey in Arizona and announced on September 19 by the Minor Planet Center, which receives funding from NASA to assist in planetary defense monitoring.
The money appears to be well spent: the center has announced the discovery of 244 near-Earth objects in September alone.
2020 SW is estimated to be passing at 7:18 am EDT (11:18 UTC) this Thursday, September 24 at a distance of 16,700 miles (27,000 km) and a velocity of 17,200 miles per hour (27,720 km/h, or about eight kilometers per second. Bullets travel at roughly 2,736km/h).
