A surprise asteroid came "relatively" close to the Earth today

The asteroid was first observed by the NASA-funded Catalina Sky Survey project, based at the University of Arizona's Lunar and Planetary Lab in Tucson, Time magazine reported.

The asteroid, named Asteroid 2018 GE3, was closest to Earth at around 2.41 a.m. ET on April 15 when it was spotted about 119,500 miles away, EarthSky.org reports.

A HUGE asteroid appeared without warning over the weekend, barely missing Earth. "During my observations, he shone like a star of 13th magnitude" - he said GE3 2018 should amount to from 48 to 110 meters in width. This puts it into the same class as the 60-meter Tunguska impactor that leveled a forest in Siberia in 1908. 2018 GE3 could be 5 to 6 times wider than that object.

SpaceWeather.com called 2018 GE3 a significant asteroid, being found less than a day before its closest approach to Earth, that might have caused regional damage had it hit earth or disintegrated in the atmosphere just before reaching the ground. Nonetheless, it is a substantial asteroid, showing how even big area rocks can still take us by surprise. Every ~2.5 years the space rock crosses the orbits of Mercury, Venus, Earth, and Mars-although not necessarily making close approaches to the planets themselves.
