Colossal 460-foot asteroid to buzz Earth today; NASA reveals what makes it special
Although smaller asteroids make close approaches with Earth nearly every day, bigger asteroids seldom do so. Even when asteroids come close to Earth, they do so safely or most of them burn up in the planet's atmosphere itself. However, things have changed now. An asteroid named Asteroid 2011 AG5 has been receiving a lot of attention lately from space agencies around the world as it is all set to make a close approach with Earth today. The Near-Earth Object Observations Program, commonly called "Spaceguard," discovers these objects, characterizes a subset of them, and determines their orbits to determine if any could be potentially hazardous to our planet.
But what makes Asteroid 2011 AG5 special? Here's what NASA revealed.
Asteroid 2011 AG5 was discovered on 8 January 2011 by astronomers using a 60-inch Cassegrain reflector telescope located at the top of Mount Lemmon in the Catalina Mountains in Arizona. That means astronomers and scientists have known and studied this asteroid for more than a decade. What's shocking about this asteroid is its gigantic size, which means it is nearly the size of a skyscraper!
It is approximately 460 feet in size and its orbit carries it as far out as beyond Mars' orbit and as close to the sun as halfway between Earth and Venus, according to NASA.
NASA has warned that this space rock will make its closest approach to Earth today, February 3, at just 1.8 million kilometers (about 1118468.15 mi). Although the distance might seem a lot, it is relatively a small number in astronomical distances, considering how big the asteroid is. Shockingly, this asteroid is speeding towards us at a mind-numbing 35706 kmph (about 22186.68 mph).
One asteroid that NASA is studying up close, called Bennu, has a
