The Vredefort impact structure is the largest verified impact structure on Earth. [1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed. [2] [3] The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of ...
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
The momentary black spots are shadows cast by Jupiter's moons. Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11 Jovian days, as of 2008. Measuring 16,350 km (10,160 mi) in width as of 3 April 2017, the Great Red Spot is 1.3 times the diameter of Earth. [21]
The outermost ring was identified using seismic reflection data. It is up to 130 kilometers (81 mi) from the crater center, and is a ring of normal faults, throwing down towards the crater center, marking the outer limit of significant crustal deformation. This makes it one of the three largest impact structures on Earth.
The Great Red Spot is a massive vortex within Jupiter’s atmosphere that is about 10,159 miles (16,350 kilometers) wide, which is similar to Earth’s diameter, according to NASA. The storm ...
A chain of craters on Ganymede, probably caused by a similar impact event.The picture covers an area approximately 190 km (120 mi) across. Jupiter is a gas giant planet with no solid surface; the lowest atmospheric layer, the troposphere, gradually changes into the planet's inner layers. [10]

Now, new pictures taken by the Earth-orbiting Hubble space telescope show Jupiter's red spot is smaller than it has ever been, measuring just under 10,250 miles (16,100 kilometers) in diameter. It ...
