NASA asteroid Earth approach: MILE-WIDE asteroid with its own MINI MOON set to play Earth | Science News

The binary set of asteroids, which first appeared 20 years ago, will become another close encounter with Earth this week. The US Space Agency, NASA, is following the trail of space rocks, nicknamed KW4. Grainy shots show that the asteroid is growing increasingly clear as it approaches Earth before its closest approach on May 25th.

Asteroid 1999 KW4, although NASA is classified as "potentially dangerous", will ventilate safely.

Even at its closest, space rock flies-3,216,271 miles from Earth – 13,5 times the distance to the moon.

The Asteroid 1999 KW4 is actually two objects, consisting of a larger cosmic stone measuring 0.8 miles (1.3 km) and a mini moon orbiting it.

NASA explained: "The primary body (primary) of 1999 KW4 is about 1300 meters across, but in fact it is quite a complex shape.

"It is slightly crushed on pillars and a mountain ridge around the equator, which runs all the way around the asteroid," observes the observatory.

“This comb gives a primary appearance similar to a nut or tip.

"Secondary is about 500 meters across and both asteroids circulate each other every 17.5 hours at a distance of about 1.6 miles."

NASA revealed a pixilated low-res view of the asteroid before its near-Earth approach.

The European Space Agency (ESA) said in its statement: "The aim of the test is to put the observatory and telescopes in the test to find out what information can be collected in the short term in the event of a future close approach to potentially threatening information. asteroid."

Dozens of telescopes tune the observation.

Asteroid 1999 KW4 was discovered on May 20, 1999 by LINEAR through Goldstone and Arecibo Observatories.

The asteroid orbits the Sun about every 186 days on an elliptical orbit.

The cosmic rock in the last century created a succession of close approaches to Earth and will be approached in the next approach in May 2036.

The asteroid is expected to be 1,487,292 miles away.

Previous observations revealed an asteroid 1999 KW4 is similar to a strangely shaped "rubble pile", according to the Las Cumbres California Observatory.

The approach being approached will provide even more insight into his behavior, which will prove useful for upcoming missions supported by NASA's Planetary Defense Coordination Office, which aims to study similar systems.
