From Wikipedia, the free encyclopedia

2017 VW13 is an Apollo near-Earth asteroid roughly 250 meters (820 feet) in diameter. It was discovered on 13 November 2017 when the asteroid was about 0.069 AU (10,300,000 km; 6,400,000 mi) from Earth and had a solar elongation of 110 degrees. Ten days earlier, on 3 November 2017, the asteroid had passed 0.02818 AU (4,216,000 km; 2,619,000 mi) from Earth,[2] but only had a solar elongation of 65 degrees.

2001 Earth approach

Calculating the orbit backwards it is known that the asteroid made a close approach to Earth on 8 November 2001.[2] The nominal (best-fit) solution shows that the asteroid passed about 0.001 AU (150,000 km; 93,000 mi) from Earth. But due to the uncertainties in the trajectory, the asteroid could have passed as far as 0.008 AU (1,200,000 km; 740,000 mi) from Earth. The observation arc is only 118 days, but as the observation arc becomes longer the precise distance of the 2001 approach will become better constrained.
