A 30-meter asteroid travels through the Earth in March

The US Aeronautics and Space Administration (NASA) said an asteroid discovered two years ago could "approach" our Earth on March 5. Specifically, the 2013 TX68 has an estimated diameter of 30 meters and is thought to pose no danger to the globe. However, how close it is to Earth at a distance is still a mystery to date.

According to NASA's prediction, the 2013 TX68 will skim over the green planet with the farthest distance of 14 million km, and the nearest 17,000km. The reason for such a big difference is because NASA can only monitor the asteroid above for 3 days, when it began to approach Earth on October 6, 2013.

2013 TX68 will skim across the green planet with the longest distance of 14 million km.

"Because they were not followed long enough, scientists could not accurately predict its orbit around the Sun, but they knew that it could not affect the Earth in a passing flight next month" , NASA explained. When asteroids fly over Earth next month, NASA telescopes will closely monitor without missing a moment, allowing scientists to better identify the trajectory of the 2013 TX68 around the Sun and predict other "close" times in the future.

NASA's Near-Earth Flying Object Research Center also made their prediction, suggesting that asteroids may approach Earth on September 28, 2017, with a probability of collision around 1/250. million. Even if the 2013 TX68 really "attacked" the planet, we probably wouldn't be the victim of a large-scale extinction.

The closest distance of the 2013 TX68 to Earth is still a mystery.

Three years ago, a 17-meter-diameter meteorite exploded in the sky of Russia, shattering thousands of glass doors in the city of Chelyabinsk, before falling into a frozen lake outside the town. That event did not cause any other significant damage.

What scientists are more worried about is probably the ability it can collide with satellites operating in orbit around the Earth.
