At its closest point, the asteroid – called 2018 GE3 – was just 119,500 miles away from Earth's atmosphere, about half the distance between Earth and the moon, according to NASA's Center for Near Earth Object Studies (CNEOS).
The estimated diameter of the space rock ranged from 131 to 328 feet, CNEOS reports.
The April asteroid, however, traveling at a speed of about 66,000 miles per hour, would have likely broken down "due to friction with the air" as soon as it entered Earth's atmosphere, EarthSky reported.
"However, some of an asteroid this size might have gotten through to Earth’s surface, and an asteroid this big is capable of causing some regional damage, depending on various factors such as composition, speed, entry angle, and location of impact," the space website explains.
At least three other small space rocks are set to fly past Earth on Tuesday – with the largest measuring 111 feet around.
Asteroid 2018 GE3 flew past us today, half the distance to the Moon. Around 50-100 m in diameter, it was several times the 2013 Chelyabinsk meteor, around the size of the 1908 Tunguska event ~ easily enough to destroy a city. We had less than a day's warning.
