WIRED: Meet the NASA Scientist Who Tracks Dangerous Asteroids in Earth’s Orbit

As a physicist at NASA’s Jet Propulsion Laboratory, Marina Brozovic studies and measures near-earth asteroids—you know, the ones that can potentially cause catastrophic damage. Watch as Brozovic explains how her team tracks the orbit of these large masses and how NASA would prepare if one were to come barreling towards earth.  

American Museum of Natural History: How Are Large Asteroids Tracked?

Since 2005, when the U.S. Congress mandated that NASA identify and track all near-Earth objects that are larger than 140 meters (approximately the diameter of a football field), professional and amateur astronomers have kept a tally of all potential earth-crossers. Meteorite specialist Denton Ebel, curator in the Division of Physical Sciences, explains how Near-Earth Objects …

American Museum of Natural History: What Were the Biggest Asteroids to Hit Earth?

Impact Craters on Earth, Moon and other planets provide evidence that the Earth has been struck by asteroids since it formed roughly 4.5 billion years ago. Once every few million years, an object large enough to threaten life on Earth comes along.  

Lockheed Martin: Asteroids and the OSIRIS-REx Mission

Scheduled for launch in 2016, OSIRIS-REx will return the first samples ever taken from a special type of asteroid that scientists believe holds clues to the origin of the solar system.  

American Museum of Natural History: What Is an Asteroid?

The rocky bodies that revolve around the Sun and sometimes collide with other bodies or planets are the leftovers of solar system formation. By studying their composition, scientists can learn more about the origins of our solar system 4.6 billion years ago.  

Royal Observatory Greenwich: Space Rocks

Want a stop motion explainer on asteroids, comets, meteors, and meteorites? Well, here you are. There are lots of names associated with space rocks, so what is the difference?

American Museum of Natural History: Deflecting Asteroids | Protecting the Earth from Future Catastrophic Events

Will we be able to avoid a repeat of the Tunguska event? Or perhaps even the Cretaceous–Paleogene extinction event? Although massive asteroid impacts on Earth are rare, astronomers have identified thousands of asteroids close enough to Earth to be potentially hazardous. Learn from meteorite specialist Denton Ebel, Curator in the Division of Physical Sciences, how …

Asteroid Day: We Will Rock You

Did you know that today is asteroid day? Asteroid Day is a global awareness movement to protect Earth against asteroid impacts. The original inspiration for this campaign came from Grigorij Richters’ asteroid impact disaster film 51 Degrees North – all profits from which he has now dedicated to the cause of Asteroid Day world-wide.

AMNH: Defending Earth from Asteroids with Neil deGrasse Tyson

There are about a million near-Earth asteroids that are large enough to substantially damage or destroy a major city, as evidenced by the explosion over Chelyabinsk, Russia, in February 2013 of a meteor no bigger than a large truck, which injured more than 1,000 people. With current space technology, scientists know how to deflect the …
