The largest asteroid to pass by Earth this year will swing closest on Sunday, giving astronomers a rare chance for a good look at a space rock that formed at the dawn of our solar system.<\/p>\n


\n <\/section>\n

While in astronomical terms this marks a close encounter with the asteroid\u2014called 2001 FO32\u2014NASA says there is no threat of a collision with our planet “now or for centuries to come”.<\/p>\n

The nearest it will get will be two million kilometres (1.25 million miles) away, according to the US space agency.<\/p>\n

That is roughly 5.25 times the distance of the Earth from the Moon but still close enough for 2001 FO32 to be classified as a “potentially hazardous asteroid.”<\/p>\n

“We know the orbital path of 2001 FO32 around the Sun very accurately,” said Paul Chodas, director of the Center for Near Earth Object Studies. <\/p>\n

NASA says 2001 FO32 will pass by at about 124,000 kilometres per hour (77,000 miles per hour) faster than the speed at which most asteroids encounter Earth. <\/p>\n

The asteroid is estimated to be about 900 metres (3,000 feet) in diameter and was discovered 20 years ago.<\/p>\n

Astronomers are hoping to get a better understanding of the asteroid’s size and a rough idea of its composition by studying light reflecting off its surface.<\/p>\n

“When sunlight hits an asteroid’s surface, minerals in the rock absorb some wavelengths while reflecting others,” NASA said. <\/p>\n

“By studying the spectrum of light reflecting off the surface, astronomers can measure the chemical ‘fingerprints’ of the minerals on the surface of the asteroid.”<\/p>\n

The asteroid will be at its closest to Earth at around 1600 GMT on Sunday, according to the Paris Observatory, France’s largest astronomy research centre. <\/p>\n

Amateur astronomers in some parts of the globe should be able to conduct their own observations.<\/p>\n

The asteroid will be brightest while it moves through southern skies, Chodas said.<\/p>\n

“Amateur astronomers in the southern hemisphere and at low northern latitudes should be able to see this asteroid using moderate-size telescopes with apertures of at least eight inches in the nights leading up to closest app<\/a>roach, but they will probably need star charts to find it,” he added.<\/p>\n

NASA said more than 95 percent of near-Earth asteroids the size of 2001 FO32 or larger have been catalogued and none of them has any chance of impacting our planet over the next century.<\/p>\n

NASA says the next time 2001 FO32 will be close to Earth will be 2052.<\/p>\n

Sixty-six million years ago an asteroid roughly twice the diameter as Paris crashed into Earth and wiped out 75 percent of life on the planet.<\/p>\n\n
