Asteroid Impacts: 10 Biggest Known Hits And though millions—in some cases billions—of years of erosion have made it difficult to determine the exact size of the meteorites, there is a general scientific consensus around the world's largest craters, which mark the largest asteroid impacts. Here are the ten biggest known: 1. Vredefort Crater. Asteroid impact date: Estimated 2 billion years ago. Location: Free State, South Africa. Specs: Also known as the Vredefort Dome, the Vredefort crater has an estimated radius of 118 miles (190 kilometers), making it the world's largest known impact structure.

Vesta: Facts About the Brightest Asteroid The crater averages 460 km in diameter — remember: Vesta itself is only 530 km across. It cuts an average of 13 km into the crust, and most likely formed from an impact in the asteroid’s early life.

- Earth's craters are enduring testaments to direct asteroid hits. And though millions—in some cases billions—of years of erosion have made it difficult to determine the exact size of the meteorites, there is a general scientific consensus around the world's largest craters, which mark the largest asteroid impacts. Here are the ten biggest known: 1. Vredefort Crater.

- The new largest asteroid is Vesta at 530 miles mean diameter it has only 9% of the mass in the asteroid belt. While being considered for dwarf planet-hood, a mass below guidelines for hydrostatic equilibrium, and a large crater on the south pole breaking its spheroid shape have so far kept it off the list.

- Biggest meteor craters on Earth. Vredefort, South Africa. Located at the south-west of Johannesburg, the crater is believed to have been made by an asteroid impact on Earth some two billion years ago. With an estimated radius of 118 miles (190 km), the crater is reportedly the site of the largest energy release in the world.

Fireball FAQs Meteorite finds range in size from particles weighing only a few grams, up to the largest known specimen: the Hoba meteorite, found in South Africa in 1920, and weighing about 60 tons (54,000 kg). As with the magnitude distribution of meteors, the number of meteorites decreases exponentially with increasing size.

Giant Asteroid to Pass Close to the Earth Facebook Linkedin Twitter Google+ Print Email. An asteroid that is approximately one-mile wide will come very close to the Earth on May 14, according to NASA's Near Earth Object watch. While an asteroid of this size would be cataclysmic if it hit the Earth, this one will pass safely by.Like Us on Facebook.The asteroid, designated 1999 FN53, is the largest object currently being tracked on NASA's near Earth radar.his asteroid isn't the only one to come close to the Earth this year. Next month, an asteroid codenamed Icarus, which is one-kilometer wide and flies almost three times faster than FN53, will pass even closer to the Earth at only 21 lunar distances.

How Big is Jupiter? Jupiter has a mean radius of 43,440.7 miles (69,911 kilometers), about a tenth that of the sun. However, its rapid rotation — it spins once every 9.8 hours — causes it to bulge at the equator, where the diameter is 88,846 miles (142,984 km). In contrast, the diameter at the poles is only 83,082 miles (133,708 km).

Asteroids: Fun Facts and Information About Asteroids Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 kilometers) in diameter.hey are also known as planetoids or minor planets. In total, the mass of all the asteroids is less than that of Earth's moon. But despite their size, asteroids can be dangerous. Many have hit Earth in the past, and more will crash into our planet in the future.

How Big Is Pluto? When New Horizons arrived at Pluto, it measured the diameter of the world to be 1,473 miles (2,370 kilometers) across, about two-thirds the diameter of Earth's moon. This makes it larger than the dwarf planet Eris, once thought to be larger than Pluto. Eris is 1,445 miles (2,326 km) in diameter.

As asteroids revolve around the sun in elliptical orbits, they rotate, sometimes tumbling quite erratically.

World's largest asteroid impact zone believed uncovered by ANU researchers in central Australia So together, jointly they would form a 400 kilometre structure which is the biggest we know of anywhere in the world. The consequences are that it could have caused a large mass extinction event at the time, but we still don't know the age of this asteroid impact and we are still working on it.

List of exceptional asteroids List of exceptional asteroids. Ceres is the largest and most massive asteroid and the only one that is a dwarf planet. Vesta is the brightest and second-most-massive asteroid. It suffered a crust-penetrating impact approximately one billion years ago. The following is a collection of lists of exceptional asteroids in the Solar System. For the purposes of this article asteroid means minor planet up to the orbit of Jupiter, which includes the dwarf planet Ceres. For a complete list of minor planets in numerical order, see List of minor planets. Asteroids are given a unique sequential identifying number once their orbit is precisely determined. Prior to this, they are known only by their systematic name or provisional designation, such as 1950
