Asteroid to come near to Earth: Where, when and how to watch it free of cost? NASA unravels mysteries
Earth or passing near it, this warning is more serious. It will come closer to the Earth in a few hours and you may be one of those fortunate people who may watch it. As asteroid 2011 UL21 is likely to come near us on June 27, you may get ready to watch it. According to SpaceReference, this asteroid orbits the sun once every three years and is estimated to be somewhere between 1.1 and 2.4 miles wide. According to the European Space Agency, it is one of the known near-Earth asteroids.
In a statement issued earlier, Virtual Telescope Project Scientific Director Gianluca Masi said that minor planets are those that are larger than 140 meters and can come within 7.5 million kilometers from the Earth. He also said that only the largest asteroids capable of approaching close enough to our planet are flagged as PHAs. They may not hit us, but better monitoring is required.
Speed of asteroid
According to NASA's Jet Propulsion Laboratory, asteroid 2011 UL21 may come to the Earth at the speed of around 58,000 miles per hour. It may come within 4.1 million miles of Earth. We can say that the asteroid may be approximately 17 times farther away from Earth than the moon. But in astronomical science, where distance is measured in light years, this distance is not too much. A light year is the distance covered by a ray of light in one year.
Where to watch
The Virtual Telescope Project has declared that it will livestream the approach of the asteroid free and those who
