Astronomers can guess the object’s size from its brightness, but this can produce a wide range of results. The Great Pyramid of Giza in Egypt, also known as the Pyramid of Khufu or the Pyramid of Cheops, initially stood about 480 ft tall. This means it could outstretch the Empire State Building’s 1450 ft height. Even at its smallest estimate, the asteroid outstretches the Great Pyramid of Giza in Egypt, which, historians think, was a measly 480 ft tall (or 280 Egyptian Royal cubits) when first built. Astronomers have a much better idea of the object's orbit than its size.

The asteroid, called 2018 DV1, is seven metres (23 feet) wide, according to Nasa’s Asteroid Watch programme An asteroid the same size as a bus is set to whizz between the Earth and the moon today, Nasa has revealed. The asteroid, called 2018 DV1, is seven metres (23 feet) wide, according to Nasa ’s Asteroid Watch programme. Thankfully, the asteroid is expected to be 70,000 miles (113,000 kilometres) from Earth during today’s flyby. During the pass, the asteroid will be travelling at staggering speeds of up to 11,600 miles/hour. While the asteroid is unlikely to be visible with the naked eye, The Virtual Telescope Project is hosting a free webcast of the event.

The newly-discovered space rock – named Asteroid 2018 DV1– is expected to zoom past our planet at around 5am. The Virtual Telescope Project and Tenagra Observatories will show the passing live using the 16-inch robotic telescope available at Tenagra Observatories in Arizona. Last Sunday another asteroid – 2018 DU – made a close shave with Earth, as it soared past at a distance of just 84,000 miles above the surface. 2018 DV1 will be the 18th known asteroid to flyby Earth within one lunar distance since the start of 2018 and sixth closest. PRINCE Harry and Meghan Markle will invite thousands of lucky members of the public into the grounds of Windsor Castle on their wedding day.

One asteroid came almost three times as close to our planet on January 18th and a pair of celestial wanderers made similar moves on the same day last month. The Virtual Telescope Project and Tenagra Observatories will show the passing live using the 16-inch robotic telescope available at Arizona’s Tenagra Observatories. 2018 DV1 will be the 18th known and sixth closest asteroid to fly by Earth within one lunar distance since the start of 2018. While the asteroid is expected to miss our planet, experts believe it would be worse than the impact of the 59ft asteroid - which hit the Russian city of Chelyabinsk in 2013 - if it did. An anxiety-worthy asteroid encounter will take place on March 7th, however, when a "potentially hazardous" rock bigger than Buckingham Palace will embark on a similar journey.

Washington: We can have a chance to witness a newfound near-Earth asteroid, called 2018 DV1, on Friday! 2018 DV1 is about the size of a bus and will approach within 70,000 miles (113,000 kilometers) of Earth during its flyby, according to scientists with NASA’s Asteroid Watch program. The asteroid, about 23 feet (7 meters) wide, can be seen as a pinprick of light in the sky in a live webcast, reports Fox news. The Virtual Telescope Project will host a free webcast, led by astrophysicist Gianluca Masi in Ceccano, Italy, for the event. (ANI)

Starting around 12:30 am eastern time on Friday, March 2, asteroid 2018 DV1 will be visible as a tiny dot of light whizzing by the Earth. The asteroid, which is about 23 feet across (about as wide as an orca is long), will come as close as 70,000 miles (113,000 km) to Earth. Coincidentally, its appearance will come less than a week after DU2018 zoomed past Earth about 175,000 miles away. The record, though, only goes back to 1900, and so doesn’t include the asteroid that struck Earth some 66 million years ago, and sped up the extinction of dinosaurs. (Every once in a while, an asteroid will make it through and reach the ground; whatever remains is called a meteorite.) You can watch 2018 DV1 on a live web stream freely available from the Virtual Telescope Project, which is run by Gianluca Masi, an astronomer at the Bellatrix Astronomical Observatory in Italy.

The asteroid is 23ft across similar to the size of a school bus. It is the sixth close encounter of Earth to an asteroid in 2018 alone. It will pass at a distance less than the lunar distance between Earth and the Moon. Soon after asteroid DU2018 passed close to the Earth at a distance of 175,000 miles a few days ago, astronomers came across asteroid 2018 DV1 on Monday at Mount Lemmon Observatory in Arizona which will pass at a distance of 70,000 miles which less than the lunar distance of 238,900 miles. Assuming that it is 23ft or 12m long, the asteroid is not a matter of concern due to its small size, if however, it plummets to the Earth, its impact will be around the same of what 2013 Chelyabinsk asteroid did.

You can watch the next fly-by right here soon. You can watch the sassy space rock, named 2018 DV1, whip past us right here starting late Thursday or early Friday, depending on your time zone. The news of this ominous visitor might make some people freak out, but we get fly-bys like this several times a year that pass quietly without incident. We also had another one slip between the moon and here on Monday, which the Virtual Telescope Project managed to photograph pretty clearly. You can watch via the embedded feed above.

The flyby will mark the 18th time an asteroid has passed between Earth and the moon in 2018. Because the asteroid is so small, between 20 and 40 feet in diameter, only especially powerful telescopes will be able to spot the space rock. The Chelyabinsk meteor, a superbolide, a fireball brighter than the sun, exploded 19 miles above Russia's Chelyabinsk Oblast region with the force of 500,000 tons of TNT. The SpaceDaily news network continues to grow but revenues have never been harder to maintain. The asteroid is estimated to be between 50 and 100 feet ...
