Large asteroid 1998 HL1 was held on Friday at a distance of 6.21 million km from Earth, i.e. at a distance of more than 10 times the distance from Earth to the moon. As reported on Friday the Internet portal Space.com the greatest approximation of a celestial body with a diameter of about 550 m with Earth occurred at 13:17 on the East coast USA (20:17 GMT).
The national Board of the USA on Aeronautics and research of space administration (NASA) has classified this asteroid is classified as potentially hazardous, that is, those heavenly bodies with a diameter of over 500 meters that approach the Earth about 7 million km. Following the approach of this asteroid with Earth will happen on October 26 2140, when it will be at a distance of 6.1 million kilometers from our planet.
Until now, astronomers have discovered in near-earth space, that is, to within 0.05 astronomical units, or 7 million kilometers, about 8 thousand asteroids larger than 140 m estimated planetary NASA Lindley Johnson, the number is not yet known near-earth asteroids with a diameter of 10 to 20 m could reach several million.
In October 2021, NASA plans to launch an automatic station Lucy to explore the seven asteroids in the Solar system. In April 2025 it should get close to a small asteroid Donaldchase in the asteroid belt between Mars and Jupiter, which was opened in March 1981. Then in 2027-2028 years Lucy will fly different shaped asteroids Eurobat, Balimela, Lewk and er. In addition, in 2033 the probe will study the binary asteroid Patroclus-Maneti.
