led NASA, The CNEOS website is constantly updated List of so-called near-Earth asteroids, This means that objects are creeping in relatively close to our planet. It stands out among the earliest events of this kind An encounter with asteroid number 7335also known as 1989 JA.
This property was discovered on May 1, 1989. This was done by Eleanor Helen at Palomar Observatory, USA. The orbit of the body is well known. In the year of its discovery, it was close to our planet, and then flew in 1996 and 2015, but it was much further away. Convergence this year will be closer than it was in 1989.
The body will pass us at a relative speed of 13.12 km / s, which is more than 47,000 kilometers per hour. The shortest distance would be about 4 million kilometers, just over 10 times the distance between Earth and the Moon. Scientists are confident in their calculations with an accuracy of only 153 km We can sleep well – We are not in danger of collision, astronomers reassure.
Estimated size is 1.8 km in diameter, although newer calculations make the scale smaller – the value indicates about one kilometer. Radar observations showed that the rotation period was 12 hours. The body is a class S asteroid, i.e. rocky, It is made of silicate materials – one of the most common types of asteroids.
NASA operates a website where you can track the distribution of the most interesting asteroids in the solar system. Object 7335, its orbit and current position can be checked on the NASA website.
