A few more images of the pellet-shaped 2003 SD220 from Arecibo Observatory. Some online reports are suggesting the asteroid could cause earthquakes. Asteroids can't and don't do this, unless a large one happens to hit Earth. This will pass over 6 million miles from us. No worries. Credit: NASA/NSF

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.

‘Spooky’ The Asteroid Comes Clean In New Radar Images

Spooky may be a rough character, but scary? Naw. The usual lumps and bumps, but given its small size, maybe more spherical than expected. On Halloween morning, the near-Earth asteroid 2015 TB145 (nicknamed ‘Spooky’) flew only 300,000 miles (486,000 km) from Earth and became bright enough to see in a modest-sized telescope. It was also the…

Amazing Radar Images Of 209P/LINEAR, The Comet Behind Last Week’s Meteor Shower

Welcome to the dark folds of one of the closest comets in years. The 1000-foot radio telescope dish at Arecibo Observatory in Puerto Rico pinged comet 209P/LINEAR with radar between May 23-27 and reconstructed images of its rugged surface from the echoes received in return. Cliffs and ridges dominate the landscape. Recently, dust boiled off…
