Two asteroids made close flybys of Earth on Monday (Sept. 14), in both cases showing a common occurrence that didn't put our home planet at any risk.
The first space rock, a bus-size asteroid called 2020 RF3, whizzed by our planet 58,500 miles (94,000 kilometers) away at 2:49 a.m. EDT (0649 GMT), according to the NASA Jet Propulsion Laboratory's Center for Near Earth Object Studies. That's the equivalent distance of one-quarter of the way to Earth's moon, a distance of 239,000 miles (385,000 km).
A few hours later, a smaller, car-size asteroid 2020 RD4 made a similar close pass at 65,700 miles (roughly 106,000 km), at 4:33 p.m. EDT (2033 GMT), the center added. Italy's Virtual Telescope Project also hosted a livestream for the 2020 RD4 event.
