Lee Rannals for redOrbit.com An asteroid about the size of a football stadium may slightly have a chance of impacting Earth in 2040, but new estimates show it's hardly a threat. The space rock, measuring about 460-feet in size, has a likelihood of missing Earth greater than 99 percent, according to the recent findings by scientists at a May 29 workshop at NASA's Goddard Space Flight Center. "While there is general consensus there is only a very small chance that we could be dealing...

The work of a University of Tennessee, Knoxville, professor has helped reveal a rare orbital shift and the density of an asteroid that will pass close to Earth. Josh Emery, assistant professor of earth and planetary sciences, and the team of the NASA asteroid sample return mission called OSIRIS-REx have measured the weight and orbit of 1999 RQ36. They have found the asteroid has a low density and its orbit has drifted roughly 100 miles in the last twelve years. This deviation is...

Protecting the Earth from an extinction-threatening asteroid has in the past been left up to Hollywood, which has deployed a barrage of special effects box office blockbusters that have kept deadly space rocks from smashing our planet into oblivion. But now, Scottish engineers have come up with a plausible way of dealing with asteroids that doesn´t include Hollywood special effects. Engineers at the University of Strathclyde in Glasgow are developing an innovative technique based on...

The bus-sized asteroid that flew past Earth on Friday may have garnered headlines, but it is far from alone, as experts claim that approximately 50 million objects pass by our planet each day. As previously reported here on redOrbit.com, Asteroid 2012 BX34, which was first detected on Wednesday, skimmed past Earth at a distance about one-fifth to one-sixth that of the Moon two days ago. While astronomers reportedly said that there was no cause for alarm, and that the 20- to 62-foot...

NASA has announced that it is planning to send a spacecraft to a distant asteroid in five years to gather samples of what could be the building blocks of all life on Earth. The OSIRIS-REx spacecraft, if all goes well, will intercept asteroid 1999 RQ36, orbit it for one year, and then reach out a robotic arm, touch the surface and grab up a handful of dirt and then return to Earth with the precious sample. "We call it "Ëœtouch and go'," said principal investigator Michael Drake of...

So you think global warming is a big problem? What could happen if a 25-million-ton chunk of rock slammed into Earth? When something similar happened 65 million years ago, the dinosaurs and other forms of life were wiped out."A collision with an object of this size traveling at an estimated 30,000 to 40,000 mile per hour would be catastrophic," according to NASA researcher and New York City College of Technology (City Tech) Associate Professor of Physics Gregory L. Matloff. His...

The head of the Russian space agency (Roscosmos) said Wednesday that the country is considering sending a spacecraft to a large asteroid to knock it off its path and prevent a possible collision with Earth, The Associated Press reported. "The space agency will hold a meeting soon to assess a mission to Apophis," said Anatoly Perminov. He told Golos Rossii radio that it would invite NASA, the European Space Agency, the Chinese space agency and others to join the project once it is finalized....

A previously undiscovered asteroid passed close to the Earth on Monday after being spotted just 15 hours before the close encounter. The Catalina Sky Survey discovered the asteroid about 15 hours before it came within 8,700 miles from Earth, making it the third-closest known non-impacting asteroid in documented history. Scientists said on average, asteroids the size of 2009 VA come this close to Earth about twice a year, while they impact about once every five years. Soon after 2009 VA was...

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...
