A massive asteroid will approach Earth on Thursday

The Panoramic Survey Telescope & Rapid Response System 1 telescope on Maui's Mount Haleakala Hawaii has produced the most near Earth object discoveries of the NASA-funded NEO surveys in 2015

Meanwhile, this asteroid which is nearly the size of a house will pass somewhere between 18,000-40,000 kilometers of the Earth's surface, just inside the space where geostationary satellites orbit in general.

Currently, 2012 TC4 is travelling at a speed of almost 50,000 kph, although, initially when it was recovered by the astronomers from within the deep space, its speed was exceedingly dim.

Now with an asteroid on track to safely fly past Earth in the next 24 hours, researchers are jumping on the rare chance to test an worldwide warning system to help brace for an object hitting the earth. "Not even for satellites".

How close will TC4 come to Earth?

Also, as the TC4 is expected to return to earth in 2050 and 2079, hence, we can get well prepared to counter its danger in future, if any.

The 65-foot-wide asteroid won't hit us, but NASA and other asteroid scientists are watching the flyby closely as they prepare a defense against a future space rock that could come crashing down in a big load of very bad, like the asteroid that scientists say wiped out dinosaurs 65 million years ago.

An expert has predicted the asteroid won't hit the Earth in 2050, however it could be on a collision course in 2079. TC4 is expected to approach the planet at a point south of Australia. The distance is about one-eighth the distance between the Earth and the Moon. Various space agencies around the world, including NASA, will be tracking the approaching asteroid.

Experts will find out how accurate their projections of size and distance were on Thursday, as well as study what the asteroid is made of. The asteroid is at No. 13 on the "risk list" of objects that could impact Earth.

Normally, the bigger asteroids are tracked easily, and more than 90 percent of large asteroids have been catalogued till date.
