Huge asteroid shoots past Earth at record close distance - and astronomers MISSED IT

AN ASTEROID the size of a football pitch zipped past Earth and astronomers had no idea it was coming sparking fears Earth is unprepared for a huge space rock hitting the planet.

The 110-metre long asteroid, which has been dubbed 2018 GE3 by NASA, shot by just 192,500km away – half the distance between the Earth and the Moon. Technically, the term NEO means a space object that comes within 30 million miles of our planet. As, Live Science reported, the chemical composition of some asteroids makes them less reflective to be observed from ground based optical telescopes.

Eddie Irizarry of the Sociedad de Astronomía del Caribe (Astronomical Society of the Caribbean) has been a NASA Solar System Ambassador since 2004. Asteroid 2018 GE3 is measured between 155 and 330 feet (48 to 100 meters) across. They were also said to have felt the heat that was radiating from the area when the explosion occurred.

Near-Earth Asteroids: Why Thousands Of Space Rocks Still Remain Undetected

Some 17,000 asteroids, each spanning at least 460 feet across, still remain undiscovered in our solar neighborhood.

Modi government has done little on religious violence: U.S. The miss is the closest an asteroid has come to us since records began. There are millions of these objects in our neighborhood and every now and then one gets closer than the distance between the Earth and Moon, close by astronomical standards. Plus, being close to us, near earth objects move very quickly in the sky which means telescopes also have to be pointed at the right direction at the right time.

Weekend Asteroid Flyby Confirms We're Worrying About the Wrong Space Rocks

Space Studies (distance) at the University of North Dakota. Sanctions on N. The first asteroid was Ceres, discovered by Giuseppe Piazzi in 1801. The International Asteroid Warning Network — a UN-sanctioned organization — includes NASA and other space agencies and is a global project on asteroid identification and tracking. NASA's Planetary Defense Coordination Office currently uses a large network of telescopes to scan the sky at once, but the agency has also stressed the need to bolster that effort.

NASA warns colossal asteroid BIGGER than Eiffel Tower heading to Earth THIS WEEK

Vesta, however, isn't representative of asteroid size in general. Elizabeth became a full-time freelancer after earning her M.Sc. in 2012. A giant asteroid gave Earth a surprise close shave this week, flying by at a distance of 1,92,000 kilometres, just a day after astronomers discovered the object, scientists say. There are currently over 600,000 known asteroids in our solar system. But, if we look from the perspective of size, considering objects like the one that flew past us last weekend or bigger than that, the data comes down to a few thousand asteroids.

This Huge Asteroid Was Spotted Only One Day Before It Whizzed By Earth

Tech Times' biggest stories, delivered to your inbox. Not only are asteroids small, but they're also pretty dim, at least when perceived in visual wavelengths. That's nothing compared to asteroids that make up the asteroid belt between Mars and Jupiter, which can measure to about 580 miles across,  NASA explains on its website . NASA estimated that the asteroid measures 48 to 110 meters wide — 3.6 times the size of the one that levelled 2,000 square kilometres of Siberian forest when it exploded over Tunguska in 1908.

Asteroid buzzed Earth this weekend

2018 GE3 swept by at half the moon's distance Sunday, just hours after being detected. Its size is 3 to 6 times that of the space rock that penetrated the skies over Chelyabinsk, Russia, in 2013.

It produced 185 times more energy than the atomic bomb explosion in Hiroshima. Earth received a cosmic close shave on Sunday (April 15) when a football field-size boulder passed by at half the moon's distance from our planet. The most common kind of asteroid, called a carbonaceous type , is very dark. GE3 was discovered by the Catalina Sky Survey approaching Earth on April 14th. The asteroid 2018 GE3 was first spotted on April 14 by astronomers at the Catalina Sky Survey, a NASA programme based at the University of Arizona in the U.S.

An Asteroid The Size Of A Football Field Just Sailed Past Earth And No One Noticed Until After It Passed By

Earth was caught by surprise after a football-field-sized asteroid skimmed the planet. It was not detected until hours after it had passed by Earth.

It calls the asteroid a significant one that took Earth by surprise. There were also seismic rumbles felt as far as the UK. At its closest approach, at 2:41 a.m. This kind of space rock may not reflect enough light for an optical telescope to spot it. It doesn’t take a very large object. This article is closed for comments. Similarly, in 1908, a small asteroid up to 190 metres in size exploded over Siberia’s Tunguska which ruined woodlands across 800 miles.

How a Football Field-Size Asteroid Caught Us by Surprise

Earth received a cosmic close shave on Sunday (April 15) when a football field-size boulder passed by at half the moon's distance from our planet.

The asteroid made its closest approach to Earth at 2:41 a.m. eastern time. Tunguska Event The Tunguska  event occurred on June 30, 1908, in a remote forest in Siberia. Scientists are still not sure what happened that day in Tunguska. EDT (0641 GMT), 2018 GE whipped by Earth at a distance of only 119,500 miles (192,300 kilometers), according to EarthSky . A near-Earth asteroid also moves quickly in the sky compared with a planet, because the rock is much closer to us.

Giant Asteroid 2018 GE3 Just Had A Close Call With Earth, And No One Saw It Coming

It came at a distance of 119,400 miles (192,000 kilometers) from Earth. Not much is known about the cause of the event, but it is believed that a comet  or asteroid 164 to 330 feet (50 to 100 meters) in diameter caused the explosion. There was no evidence left behind to determine what was the cause of the explosion. While a football field-size asteroid is a small rock in the context of the larger universe, it's still big for an object passing by Earth.

Asteroid the size of a football field makes 'surprise' flyby close to Earth

An asteroid the size of a football field buzzed by Earth Sunday in one of the closest encounters the planet has seen in a while.

To keep that in perspective, the moon is 238,900 miles (385,000 kilometers) away from Earth. It flattened 80 million trees in the forest. No scientists explored the region until almost 20 years later. Most asteroids reside in the asteroid belt, which lies between the orbits of Mars and Jupiter. Run through the agency's Planetary Defense Coordination Office, the program uses a large network of telescopes to scan the skies.

Giant asteroid 2018 GE3 makes surprise fly-by past Earth

The asteroid measure 3.6 times the size of the one that levelled 2,000 square kilometres of Siberian forest when it exploded over Tunguska in 1908.

The asteroid  was first observed by the Catalina Sky Survey at the early hours of Saturday. The nearest town was over 35 miles (60 kilometers) away. This was due to the remoteness of the site and the problems that Russia was facing at the time that this occurred. There are, however, some asteroids that pass by Earth. Elizabeth Howell is a regular contributor to Live Science and Space.com, along with several other science publications.

Though nothing happened in this case, many wonder how many of these near-Earth objects (NEOs), exists in our neighborhood and why it is so late that we detect them, at least in some cases. It’s just that it gets really difficult to observe objects like these in visual wavelength, especially when they are small or medium-sized and dim. Illustration of the orbit of asteroid 2018 GE3.
