This week, a building-size asteroid passes “close” to Earth

As reported by the Tech Times, through the Center for the Study of Near-Earth Objects , belonging to NASA, asteroid 163348 (2002 NN4) will pass about 5.09 million kilometers from our planet (about 13 times the distance that is the Moon), traveling at a speed of 11,146 kilometers per hour.

The rock, whose diameter is calculated between 250 and 570 meters, is larger than 90% of the celestial bodies that have ” approached ” Earth until now. If the calculations are right, the body will be even larger than the famous 443 meter high Empire State Building. In fact, NASA classified it as “potentially dangerous” due to its size and trajectory, although the likelihood that it will impact our planet is practically nil.

It is also known that the 2002 ” Aton ” class NN4 orbits the sun every 300 days (0.82 years) and completes a rotation about its axis every 14.50 days. According to the trajectory of their orbits, there are three types of objects that can approach Earth: the so-called ” Love “; the ” Apollo “, and the ” Aton “.

The latter, like 163348 (2002 NN4), have an orbit with a semi-major axis shorter than that of Earth (an astronomical unit, that is, the average distance between Earth and the Sun), according to La Nación . NASA also reported that five other small celestial bodies, about 20 meters in diameter, will approach Earth on June 2.Of these, the 2020 KK7 will be the closest, up to 513,120 kilometers, somewhat more than the distance from Earth to the Moon.
