The Earth Asteroid 2017 YE5 was spotted for the first time by astronomers in December 2017, but little was known about the space rock.
A year later, on June 21, 2018, the asteroid approaching the planet NASA astronomers at the Goldstone Sola System Radar (GSSR) in California determined that YE5 was not the only source of the planet. was not one of the most important on the planet. one, but two asteroids – a so-called binary system.
The observations of the SRSG revealed two very distinct forms that dance in space.
New photos from NASA's binary system provide the most detailed observations of this unusual phenomenon.
A NASA Jet Propulsion Laboratory (9JPL) release stated: "Scientists at the Arecibo Observatory in Puerto Rico had already planned to observe 2017 YE5, and they were alerted by their colleagues at Goldstone's The unique properties of the asteroid
"On June 24, scientists teamed up with researchers from the Green Bank Observatory (GBO) in West Virginia and used the two observatories together in a radar configuration bi-static. they were able to confirm that 2017 YE5 consists of two separate objects.
"On June 26, Goldstone and Arecibo both confirmed the binary nature of the asteroid."
NASA astronomers have now determined that asteroids once every 20 to 24 hours
Scientists estimate that asteroids measure about 3,000 feet each.
If asteroids were ever to crash on the planet, the effect could be devastating on an unimaginable scale.
1908 The asteroid of Tunguska, which reportedly exploded in Siberia, was between 200 and 620 feet and destroyed 2,000 square kilometers of forest.
NASA clbadifies all objects near the Earth whose size is greater than 460 feet. a serious risk for entire regions or continents.
A White House report published in 2018, co-published by NASA on the US's disposition to treat rogue asteroids, warns that it is impossible to track all these asteroids. report read: "Such objects would strike the Earth with a minimum energy of more than 60 megatonnes of TNT, which is more than the most powerful nuclear device ever tested."
Fortunately the asteroid YE5 appears orbiting sun at a safe distance from the Earth
At its closest approach, the asteroid was 16 times the distance between the Earth and the Moon
YE5 is the fourth binary ever observed the two separate bodies do not touch each other.
