The main asteroid, the 2013 CW32, was spotted for the first time in 2013: it measured 250 meters and traveled a distance of 36,775 miles at the time.
The proximity of the Earth should pbad a safety distance of 5020 654 km (about 14 times the distance between the Earth and the Moon).
In fact, another asteroid travels the Earth today as well, but much smaller. He travels through the AN11 2019, which was spotted for the first time this year at 28,000 kilometers at the time.
It is difficult to see asteroids through the telescope because they are often very small and weak, with varying levels of reflection.
NASA has identified 10 objects close to Earth, constituting the closest flight to the planet just in November.
