Pasadena, CA – NASA scientists at the agency’s Jet Propulsion Laboratory in Pasadena, CA, effectively have ruled out the possibility the asteroid Apophis will impact Earth during a close flyby in 2036.

The scientists used updated information obtained by NASA-supported telescopes in 2011 and 2012, as well as new data from the time leading up to Apophis’ distant Earth flyby.

Pasadena, CA – A scientist at NASA’s Jet Propulsion Laboratory in Pasadena, CA, has accurately determined the mass of a nearby asteroid from millions of miles away.

The celestial equivalent of “guess your weight” was achieved by Steve Chesley of JPL’s Near-Earth Object Program Office by utilizing data from three NASA assets – the Goldstone Solar System Radar in the California desert, the orbiting Spitzer Space telescope, and the NASA-sponsored Arecibo Observatory in Puerto Rico.
