Asteroid 2012 JU Zips Close By Earth

An asteroid with the size of a school bus gave Earth a close shave on May 13, passing well inside the orbit of the moon. According to NASA’s Near-Earth Object Program at the Jet Propulsion Laboratory in Pasadena, Calif the near-Earth asteroid 2012 JU, which is thought to be about 40 feet (12 meters) wide, came within 119,000 miles (191,500 kilometers) or so of our planet before zooming off into deep space.

Asteroid 2012 EG5 Close Approach

An asteroid with the size of a passenger jet zoomed near the Earth Sunday, on April 1,2012. The asteroid, which called 2012 EG5, was closer than the moon when it flew by Earth at 5:32 a.m. EDT (0932 GMT). According to Nasa the space rock is about 150 feet wide (46 meters). The asteroid 2012 EG5 crept within 143,000 miles (230,000 kilometers) of Earth during its closest approach, which is just over half the distance between Earth and the moon’s orbit.

Two Tiny Asteroids Zipped Close by Earth

Two small asteroids zipped close by Earth on March 26 2012, passing between our planet and the orbit of the moon. As said Nasa scientists this two asteroids not pose any threat of impacting our world. The two space rocks flew by Earth in rapid fire. According to astronomers with NASA’s Asteroid Watch program, one asteroid zoomed by early in the day while the second buzzed the planet at 1:09 p.m. EDT (1709 GMT).

Tiny Planet Mercury May Be Hiding Water Ice

New evidence from the first probe to orbit Mercury is building support for the idea that the tiny planet may be harboring water ice in some of its most extreme terrain. Certain areas of Mercury’s poles were previously found to be bright in radio waves detected by radar measurements from the Arecibo Observatory in Puerto Rico. Now, the Messenger spacecraft has found that those same bright radar spots appear to be in permanent shadow, according to camera views from the probe’s Mercury Dual Imaging System (MDIS).

Dawn Sees Bright Spots on Giant Asteroid Vesta

NASA’s Dawn spacecraft has revealed unexpected details on the surface of the giant asteroid Vesta. The new photos of Vesta from NASA’s Dawn spacecraft highlight odd, shiny spots that are nearly twice as bright as other parts of the asteroid, suggesting it is original material left over from the space rock’s birth 4 billion years ago, NASA officials said on March 21. With a width of about 330 miles (530 km), asteroid Vesta is one of the largest and brightest objects in the main asteroid belt between the orbits of Mars and Jupiter.

Martian Rocks Crashed to Earth in July

A hail of Martian meteorites crashed to Earth last July, and collectors and scientists around the world are snapping up the ultra-rare rocks for display and study.The meteorites fell in the Moroccan desert in July and were recovered a few months later. Scientists confirmed on January 17 that the rocks are Martian, presumably blasted off the Red Planet by an asteroid strike. The rocks are a rare treat for researchers, allowing them to investigate relatively pristine chunks of Martian material. Martian material is exceedingly hard to come by on Earth. Just 220 pounds (100 kilograms) of Mars rocks are known to exist on our planet, According to Darryl Pitt, curator of the Macovich Collection of meteorites in New York City.
