How big is an average meteorite?

Answer 1

Ceres, now classified as a dwarf planet, was long regarded as the largest asteroid in the solar system at 588 miles across. It is now ambiguous as to whether Ceres still qualifies as an asteroid. If not, then the largest known asteroid is Vesta with a mean diameter of 326 miles.

Answer 2

The size of meteoroids ranges from the size of a speck of dust to

the size of the thing that created the Barringer Crater in Arizona.

The bigger they are, the more rare they are.

Answer 3

It's a big hard to talk about "average", if you have a few large meteorites, lots of smaller ones, and even more that are the size of a grain of dust or even microscopic. I guess if you "average" all those, you'll get the size of a grain of sand or less.

Anything above 10 meters is usually considered an "asteroid", so that - ca. 10 meters - is the largest size for a meteorite, by definition.

Answer 4

They vary in size. They may be just dust, but they can be large rocks.

Answer 5

A meteorite is a meteor that reaches Earth. There is no size limit for a meteorite. They can be as small as a grain of rice or as large as a building.
