Judging from the picture above, that was a really a close call for Earth.

The asteroid, which NASA named as Asteroid 2013 LR6, actually past Earth four times last Saturday as it took a path between the Earth and moon.
NASA first discovered the asteroid on Friday at 12:42 a.m. EDT about 65,000 miles away over the Southern Ocean, south of Tasmania, Australia with a size of 30-foot wide.

According to NASA, the size of this asteroid which is similar to a small truck is not enough to endanger the Earth but they are more concerned about the frequency of celestial objects moving across our planet as more asteroids are being discovered often.

Just a week ago, asteroid EQ2 was fairly huge with its size of 1.7 mile wide passed between the Earth and moon with a distance of 5.8 million km.

Another famous incident on February 15 was the asteroid that exploded over the city Chelyabinsk, Russia leaving more than 1,500 casualties as broken glass windows flew around the area of the establishments. The scientists named it Chelyabinsk meteor which dashed towards the city like a fireball has a speed of 41,000 mph—almost the speed of sound. It was so bright that it was even seen by the neighboring country Kazakhstan. No warning was received by the public from NASA and even its own space agency Russian Federal Space Agency. Both agencies didn’t expect the impact as it was only running 30 km/s when it first entered Earth’s atmosphere.

"There is theoretically a collision possible between asteroids and planet Earth," astronomer Gianluca Masi, with the Virtual Telescope project, said during a Google+ webcast as they watched a live telecast of the asteroid LR6.

NASA is now monitoring more large asteroids approaching the Earth with at least 0.65 miles size. An asteroid of that size once hit the Earth and became the Yucatan peninsula located in Mexico which scientists said that may have caused the death of the dinosaurs.
