This collage shows six planetary radar observations of 2011 AG5 a day after the asteroid made its close approach to Earth on Feb. 3. With dimensions comparable to the Empire State Building, 2011 AG5 is one of the most elongated asteroids to be observed by planetary radar to date.
We are nowhere close to defending Earth from a cataclysmic asteroid - Big Think
Last September, NASA smashed a spacecraft into a small asteroid. The results were impressive, as shown in the image above.
The Double Asteroid Redirection Test, or DART , was a success as a prototype technological demonstration. But what can we say about the impact of the mission? What does it mean for our chances of defending the planet from cosmic calamity? Unfortunately, not much — not yet, anyway.
Small Asteroid Spotted Hours Before Demise - Sky & Telescope - Sky & Telescope
The swift detection of a small asteroid, and recovery of its surviving fragments, shows we're getting better at spotting incoming objects.
An meteorite fall this week put key detection methods for incoming asteroids to the test, resulting in swift recovery of surviving fragments.
Big asteroid to zoom by Earth on Wednesday | Space
A sizable space rock will make its closest approach to Earth in four centuries on Wednesday evening (Feb. 15), but there's nothing to fear.
The near-Earth asteroid 2005 YY128 will zoom within 2.8 million miles (4.5 million km) of our planet at 7:46 p.m. EST on Wednesday (0046 GMT on Feb. 16) — closer than it's gotten to us in more than 400 years, according to EarthSky.org (opens in new tab) .
