This week the asteroid named 2017 BX only just missed the Earth, zipping past at distance of 162,252 miles, which is 30 percent closer than the distance between the Earth and the moon.
On top of that, the asteroid is about the size of a bus, it is estimated by NASA’s Asteroid Watch team to be around 28 feet or 8.5 meters wide.
TheMinor Planet Center at the Harvard-Smithsonian Center for Astrophysics have also said that it could be between 13 and 46 feet in diameter (4 and 14 meters), however, there’s no way to know precisely which one is correct.
This is the second this that a small asteroid has sped past the Earth this year, another asteroid named 2017 AG13 also flew post on Jan. 9th.
As you can see from the video above, 2017 BX could be seen from the ground quite clearly, despite it being relatively dim and extremely fast at a massive 17,000mph, you can watch it move quite clearly in the sky in the video.
That said, it was harder to find from a telescope and that’s why it was only detected by the Pan-STARRS 1 observatory at the summit of Haleakala in Maui, Hawaii on January 20th.
