This collage of radar images of near-Earth asteroid 2015 TB145 was collected by the Arecibo Observatory on October 30, 2015. The images show the rotation of the space rock, which made its closest approach on October 31 at 1 p.m. EDT (10 a.m. PDT) at a distance of 302,000 miles (486,000 km) – about 1.3 times the distance from Earth to the Moon.
