The impact occurred southwest of what is now Johannesburg, South Africa, and temporarily made a 40-kilometer-deep and 100-kilometer-wide dent in the surface. Almost immediately after impact, the crater widened and shallowed as the rock below started to rebound and the walls collapsed.
Where is the biggest asteroid crater on Earth?
In South Africa, the Vredefort Crater, also known as the Vredefort Dome is the world’s largest known impact crater, according to NASA Earth Observatory.
How big was the asteroid that hit South Africa?
With an estimated original diameter of 300 kilometers, the Vredefort Impact Crater is the largest asteroid impact structure that still has visible evidence at Earth’s surface.

How old is Vredefort crater?
The Vredefort Dome is 120 km south west from Johannesburg. The property represents a unique geological phenomenon formed about 2 023 million years ago and is the oldest and largest known meteorite impact structure on earth.
How big was the meteorite that hit Sudbury?
10 to 16 kilometres
A meteorite believed to be 10 to 16 kilometres in diameter hurtles from space striking the area now known as Sudbury, Ontario (700 kilometres away)! An impact crater 250 kilometres wide is created, which forms the second biggest known crater on our planet (Figure 2).
Where is Vredefort Dome?
Vredefort Dome, approximately 120 km south-west of Johannesburg, is a representative part of a larger meteorite impact structure, or astrobleme. Dating back 2,023 million years, it is the oldest astrobleme yet found on Earth.

How big was the Vredefort meteorite?
300 kilometres
The Vredefort crater, with an estimated diameter of 300 kilometres, is the world’s largest known impact structure. It was created when an asteroid measuring at least 10 kilometres landed on Earth an estimated 2 billion years ago.
Where is bennu in the solar system?
It likely formed in the Main Asteroid Belt between Mars and Jupiter, and has drifted much closer to Earth since then. Because its materials are so old, Bennu may contain organic molecules similar to those that could have been involved with the start of life on Earth.
Is there a crater in Antarctica?
Evidence of 2,000km-wide asteroid impact crater in Antarctica discovered. The discovery indicated a so-called low-altitude meteoritic touchdown event – where a jet of melted and vaporised material from an asteroid at least 100 metres in size reached the surface at high velocity.
What is the Vredefort structure?
The Vredefort structure is currently regarded the biggest and oldest clearly visible impact structure on Earth. The force of the impact opened up a crater, which is still visible, and is about 40km in diameter. When visiting the area you will notice small hills in a large dome shape with beautiful valleys between them.
Where is the Vredefort Dome located?
The complete Vredefort Dome structure extends over a circular area with a diameter of 300 km. It stretches from above Johannesburg in the north east to Welkom in the south west. At the approximate centre of the Dome is a small town called Vredefort.
Where is Vredefort crater located on a map?
Map of Vredefort Crater: Map showing the approximate footprint of Vredefort Crater in the country of South Africa. The dotted line marks the approximate location of the original crater rim, which has been obscured by erosion in the northwest and covered by sediments in the southeast.
Where can I abseil around Vredefort Dome?
Earth Adventures offers safe and exciting abseiling at a number of venues around the Vredefort Dome. Thrill seekers can chose from a number of available abseiling Overnight?
