2010 WC9

We continue tracking the close approach of 2010 WC9. 2010 WC9 is an Apollo-type asteroid with a diameter of 60-130 metres. Discovered at Catalina Sky Survey in November 2010, it was subsequently lost, until its rediscovery on May 8th, 2018. 2010 WC9 will make a particularly close approach on May 15th, at a distance of 203,000 km from Earth (0.00136 AU, about half the distance to the Moon). It is currently visible at +15 mag and brightening rapidly. 2010 WC9 is expected to reach 11th magnitude on the day of closest approach (May 15th), bright enough to be seen with a small telescope. This will be one of the closest approaches by a "large" (~100m) asteroid ever observed. #SpotTheAsteroid Northolt Branch Observatories Asteroid Day NEOShield-2
