2018 WV1 was found on November 29 at the Catalina Sky Survey in Arizona, USA There will be a close encounter on Sunday morning, which is within 27,000 km of the Earth's surface – closer than the geostationary satellites.
Apart from its very close approach, 2018 WV1 is interesting for several reasons, one of which is very low speed relative to the Earth: This makes it very likely that 2018 WV1 is a lunar ejection piece, a lunar fragment ejected into space when a larger asteroid hit the Moon long ago.  When WV1 was discovered in 2018, the first orbit in early December had a 2 percent chance of hitting the Earth. Fortunately, this possibility was ruled out soon afterwards.
Even if it had hit us, the object is too small to be a threat.
To further refine orbit, we watched WV1 this evening [Northolt Branch Observatories] 2018. The asteroid was at that time at a distance of 285,000 km [177,000 miles] from Earth and was still approaching a weak object of the order of magnitude  .
According to The Watchers, observatories on Earth have detected 70 asteroids at a distance of 1 moon since the beginning of 2018.
29. On December 2nd, it will be closer to Earth than geosynchronous satellites.
EarthSky lunar calendars are cool! They make great gifts. Order now. Go fast!
