An asteroid that could be longer than a football field will soon be uncomfortably close to our planet, experts say.
Scientists are observing an asteroid of considerable size coming very close to Earth very soon. The Asteroid 2010 WC9, first unveiled on November 30, 2010 by the Catalina Sky Survey in Arizona, is back for another visit, and it will be at an incredible distance of about half the distance that the Moon takes us is.
When astronomers were first discovered in 2010, astronomers were unable to predict when they would be back due to unclear orbit data. But on May 8, eight years later, astronomers rediscovered the asteroid and identified it as a long-lost WC9 in 201
The asteroid will fly past the Earth at an incredible 28,000 miles per hour, and it will be between 60 and 130 meters. That would probably be bigger than the Chelyabinsk meteor, which was about 65 feet long (only about 20 meters) and damaged thousands of buildings when it hit the city in 2013.
You can actually see it live as it passes, thanks to Nortolt Branch Observatories.
"We discussed the unusual object 2010 WC9 with EarthSky! Check out the link to it, with more information about this asteroid, why it's special and how you can see it yourself," it says on its Facebook page , "If you want to watch the asteroid from your couch, you can do that as well: we plan to broadcast live from the telescope on the evening of May 14 (the day before the next approach), weather permitting, we will detail Share it on our Facebook page on Monday. "
" Asteroid 2010 WC9 will pass approximately half the lunar range on Tuesday, May 15, 2018. Estimates of its size range from 197 to 427 feet (60-130 meters) making May 15 one of the closest encounters ever seen on an asteroid of this size, "explains EarthSky. "This asteroid was" lost "and then found again.The Catalina Sky Survey in Arizona first detected it on November 30, 2010, and astronomers watched it until December 10, when it became too weak to see did not have enough observations to fully track their orbit and predict their return: on May 8, 2018, nearly eight years later, astronomers discovered an asteroid and gave it the temporary designation ZJ99C60, and then they discovered that Asteroid returned to WC9 in 2010 . "
Daniel Bamberger of Northolt said on his Facebook page that the object had been mapped twice.
"We pictured this object twice: first on May 9, when it was still known by its temporary designation ZJ99C60; then again on May 10, after it was identified as the 2010 WC9 Asteroid, which has been in use for eight years lost asteroid, "he wrote. "It's still a fragile 18th-size object, but it's getting brighter very quickly: in 2010, WC9 gets brighter than the 11th magnitude on closer approach, making it visible in a small telescope!"
The following is a Wikipedia excerpt on nearby -European objects
A near-Earth object (NEO) is a small body of the solar system whose orbit can bring it close to Earth. By definition, a solar system body is a NEO when its shortest approach to the Sun (perihelion) is less than 1.3 astronomical units (AU). When the orbit of a NEO crosses the earth and the object is larger than 140 meters, it is considered a potentially dangerous object (PHO). Most known PHOs and NEOs are asteroids.
Known NEOs comprise more than seventeen thousand near-Earth asteroids (NEAs), more than a hundred short-period near-Earth comets (NECs), and a number of orbiting spacecraft meteoroids large enough to be traced in space before hitting Earth. It is now generally accepted that collisions in the past have played a significant role in shaping the Earth's geological and biological history. NEOs have been of increasing interest since the 1980s due to greater awareness of the potential hazard posed by some asteroids or comets, and methods of mitigation are explored.
Based on NEO's orbit calculations, there is a risk of future impacts assessed on two scales, the Turin scale and the more complex Palermo scale, both of which classify a risk of significance greater than zero. Some NEOs had positive initial Torino or Palermo ratings after their discovery, but from March 2018, more accurate calculations based on subsequent observations always resulted in a reduction of the rating to or below 0.
Since 1998, the United States has been seeking , the European Union and other nations under the name Spaceguard after NEOs. The original goal of cataloging at least 90% of NEOs that are at least 1 km (km) wide – about 0.62 miles (miles), which would cause a global catastrophe if impacted on the Earth – had been achieved by 2011 In later years, surveying efforts were extended to just 140 meters in size, which still has potential for major, if not global, damage.
Due to their earth-like orbits and their shallow depth surface gravity, NEOs are lightweight targets for spacecraft. In March 2018, five near-Earth comets and three near-Earth asteroids were surveyed by spacecraft and probes are on their way to two other NEAs. Plans to promote NEA commercially were picked up by a private company.
