An asteroid the size of a bus is set to make a close fly-by of Earth on September 24.?
According to reports, the object will travel some 13,000 miles away from Earth, which is closer than moon and weather satellites floating in space.
The asteroid, dubbed 2020 SW, measures around 4.4 - 9.9 metres in diameter. At the higher end of that estimate, it could be roughly the same size as a London bus!
The closest approach will occur Thursday morning over the southeastern Pacific Ocean.??

Asteroids of this size hit Earth's atmosphere and burn up once every year or two, according to Paul Chodas, director of the Centre for Near-Earth Object Studies at NASA's Jet Propulsion Laboratory. ???????
There could be as many as 100 million of these little asteroids out there.

"In fact, asteroids of this size impact our atmosphere at an average rate of about once every year or two," Chodas added.?
JPL also notes that the asteroid will fly past Earth closer than the moon orbits, which is about 240,000 miles away, and make a close approach below the ring of geostationary satellites orbiting about 22,000 miles from our planet.
Fortunately, the asteroid is not on an impact trajectory with earth, and if it were, our atmosphere would likely break it apart, creating a bright meteor, known as a fireball.
Another asteroid called 2018 VP1 is projected to make a close pass on the day before the US Election Day.The 6.5-foot asteroid poses no threat to Earth and its puny stature would be no match for our atmosphere, even if it had an impact trajectory with earth.
