How big of an asteroid would destroy a city?
If an asteroid the size of an apartment hits Earth, this blow could possibly destroy a small city. If an asteroid the size of a 20-storey building hits Earth, this blow can completely flatten a small country.
Where is the largest meteorite?
But the largest meteorite on earth is this monster, named Hoba. It is located in Namibia, and has never been moved. Hoba is nearly twice the weight of its nearest rival El Chaco at 60 tonnes. This makes it the biggest naturally occurring piece of iron known on Earth’s surface at 6.5 square metres.
Where was the largest meteorite discovered?
It is the largest known intact meteorite (as a single piece) and about twice as massive as the largest fragment of either the Cape York meteorite’s 31-tonne Ahnighito kept in Manhattan or the Campo del Cielo’s 31-tonne Gancedo in Argentina….Hoba meteorite.

How big does a meteor have to be for a crater?
However a meteorite doesn’t have to be large to make a great impact – the Barringer Crater in Arizona (pictured above), which has a diameter of almost a mile (1.6 kilometres) across, was made by a chunk of space rock about 0.02 to 0.03 miles (30 to 50 metres) in diameter.
How big does a meteoroid have to be to hit Earth?

How big is the dust that causes meteors?
If you’ve spent much time looking up at the night sky, you’ve probably seen some spectacular meteors and meteor showers. One of the most amazing things about these displays is that the majority of the space dust that causes visible meteors is tiny — between the size of a grain of sand and the size of a small pebble.
Do all meteoroids that enter the atmosphere make it to Earth?
In this sense, most all meteoroids that enter the atmosphere make it to the ground, in the form of microscopic dust. As for meteoroids big enough to form visible meteors, estimates for the minimum size vary.
