Experts say that an asteroid longer than a football field will soon be uncomfortably close to our Earth. The asteroid measures between 197 and 427 feet in diameter. Again find a heavenly body was only may 8, 2018.
Despite its seemingly large size, the asteroid will not be visible to the naked eye from Earth.
"We imaged this object twice: first on May 9th, when its provisional name was ZJ99C60; then on May 10th it was once again identified as asteroid 2010 WC9".
In February of 2018 in Russian Federation offered for United States dollars 210 billion to create a fusion megarocket to repel the attack from outer space (asteroid defense weapon).
A very big asteroid is expected to fly by earth at 28,655 miles per hour on Tuesday - but will probably miss.
Space rock "Asteroid 2010 WC9" will have a near-Earth encounter, about half the lunar distance, on May 15, media reports said.
The jumbo jet-sized asteroid 2010 WC9 is approaching the earth's neighborhood and will zoom past getting as close as 126,000 miles from us on Tuesday at speeds estimated to be approximately 29,000 miles per hour. They lost it in 20 days and were neither able to determine the asteroid's complete orbit nor predict when it might make a comeback.
It is not uncommon for objects to pass as close to the Earth: 60 known objects have passed at similar distances to the Earth in 2016, 56 in 2017, 33 in 2018 so far.
Guy Wells, of the observatory, said: "We are planning to broadcast this asteroid live to our Facebook page if the weather forecast remains positive". Your best bet for generating a refined track for the asteroid is to use NASA JPL's Horizons web interface to generate Right Ascension/Declination coordinates for the 2010 WC9 for your location. The asteroid will move pretty fast (30 seconds of arc per minute).
Daniel Bamberger, also at Northolt Branch Observatories, sent along the two images below. The effort goes on all the time, but on some occasions, the size, speed, and chemical composition of these objects make it extremely hard to observe them in visual wavelength.
