News: Bus-Size Asteroid to Give Earth Close Shave Friday
A small asteroid will pass close to Earth Friday (27 January), which comes much closer to the moon, but the space rock poses no danger of impacting our planet, scientists say NASA.the newly discovered asteroid 2012 BX34, which is about the size of a city bus, will pass within 36,750 miles (59.044 kilometers) from Earth at around 10:30 am EST (1530 GMT) Friday, astronomers with the program Asteroid watch NASA announced via Twitter.
the space rock is about 36 feet (11 meters) wide, so it is too small to threaten to Earth.
"would not get through our atmosphere intact even if he did not dare to try," he tweeted the asteroid View scientists today (January 26). Asteroid Watch is based on the Jet Propulsion Laboratory of NASA in Pasadena, California.
The asteroid 2012 BX34 will zip a distance of about 0.17 times that between Earth and the Moon. The moon revolves around the Earth at an average distance of about 240,000 miles (386,000 km).
While the asteroid close to Earth will not hit Earth, you can provide experienced amateur astronomers a great show - if they are in the correct location display and have a good team
"Stargazers advanced amateurs might be able to watch the flyby of the asteroid brightens to 14th magnitude. just before closest approach on Friday, "the Spaceweather.com website reported today.
the classification system astronomers, higher magnitudes correspond to fainter objects. The full moon, for example, has a magnitude around -12.75. A magnitude of 14 would put 2012 BX34 roughly on par with the maximum brightness of the distant dwarf planet Pluto.
Scientists NASA and other teams of astronomers regularly monitor the skies for asteroids that could pose a danger to Earth. Experts estimate that asteroids measuring about 460 feet (140 m) wide can cause widespread destruction near their impact, but it would be even larger to cause global devastation.
last September, NASA announced that it had cataloged about 90 percent of the largest asteroids whose orbits bring them close to Earth - an important goal set by Congress in 1998. the recent use mapping asteroid mission NASA WISE guide scientists estimate that there are about 981 near-Earth asteroids the size of a mountain or greater. About 911 of these space rocks have been seen, scientists from the WISE mission said.
The search and mapping the orbits of such potentially dangerous space rocks is a crucial task for long-term survival of our species, many scientists say.
throughout history, asteroids big enough to cause extensive damage and disruption to the economy and society overall (who went on strike a populated area today) have hit Earth, on average, every 200 or 300 years, the former astronaut Rusty Schweickart.
Schweickart chairs the B612 Foundation, a group dedicated to predicting and preventing catastrophic asteroid impacts on Earth. main message of this group is that the survival of humanity someday depend on our ability to deflect a murderer asteroid of the Earth.
The dinosaurs did not have the technology, of course, and a catastrophic impact wiped them - along with many other species of plants and animals - 65 million years
