Fortunately though it will be keeping its distance and won't came any closer than 6.7 million miles."The 2015 apparition is the first of five encounters by this object in the next 12 years when it will be close enough for radar detection," wrote NASA astronomer and asteroid expert Lance Benner.

Detecting and observing near-Earth asteroids is particularly beneficial, not only because it can help us to better understand the composition and origins of these objects but because NASA is hoping to land humans on an asteroid in the future as part of its program to send astronauts to Mars.

Stargazers should also be in for a treat when the asteroid reaches its closest approach next week.
