NASA reports Three Radio Telescopes discover Double Asteroid

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New observations by three of the world’s largest radio telescopes have revealed that an asteroid discovered last year is actually two objects, each about 3,000 feet (900 meters) in size, orbiting each other.

Near-Earth asteroid 2017 YE5 was discovered with observations provided by the Morocco Oukaimeden Sky Survey on December 21st, 2017, but no details about the asteroid’s physical properties were known until the end of June. This is only the fourth “equal mass” binary near-Earth asteroid ever detected, consisting of two objects nearly identical in size, orbiting each other. The new observations provide the most detailed images ever obtained of this type of binary asteroid.

NASA reports a Large Asteroid will Pass Safely Pass by Earth on September 1st

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Asteroid Florence, a large near-Earth asteroid, will pass safely by Earth on September 1st, 2017, at a distance of about 4.4 million miles, (7.0 million kilometers, or about 18 Earth-Moon distances). Florence is among the largest near-Earth asteroids that are several miles in size; measurements from NASA’s Spitzer Space Telescope and NEOWISE mission indicate it’s about 2.7 miles (4.4 kilometers) in size.

“While many known asteroids have passed by closer to Earth than Florence will on September 1st, all of those were estimated to be smaller,” said Paul Chodas, manager of NASA’s Center for Near-Earth Object Studies (CNEOS) at the agency’s Jet Propulsion Laboratory in Pasadena, California.

NASA studies Comet P/2016 BA14 as it passes by Earth

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers were watching when comet P/2016 BA14 flew past Earth on March 22nd. At the time of its closest approach, the comet was about 2.2 million miles (3.5 million kilometers) away, making it the third closest comet flyby in recorded history (see “A ‘Tail’ of Two Comets”). Radar images from the flyby indicate that the comet is about 3,000 feet (1 kilometer) in diameter.

The scientists used the Goldstone Solar System Radar in California’s Mojave Desert to track the comet.

These radar images of comet P/2016 BA14 were taken on March 23, 2016, by scientists using an antenna of NASA's Deep Space Network at Goldstone, California. At the time, the comet was about 2.2 million miles (3.6 million kilometers) from Earth. (NASA/JPL-Caltech/GSSR)

NASA - National Aeronautics and Space AdministrationPasadena, 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.

NASA Jet Propulsion Laboratory Scientist accurately determines the Weight of an Asteroid

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.
