(ScienceFactz) An asteroid the size of a bus safely flew past Earth yesterday morning, ahead of a larger house-sized asteroid that will skim our planet next week.
The first was called 2017 SX17, measuring about 8 meters (26 feet) wide. It passed within 87,000 kilometers (54,000 miles) of our planet at 6.20am EDT (10.20am GMT) yesterday, October 2, about one-third the distance of the Moon.
While it came close, the asteroid posed no threat to Earth. NASA tracks asteroids of this size and 2017 SX17 had no chance of hitting us on its 476-day orbit around the Sun.
