Which is bigger meteoroids or asteroids?

Answer 1

No. A meteoroid is a sand- to boulder-sized particle of debris in the Solar System, while asteroids are small Solar System bodies in orbit around the Sun; they are smaller than planets but larger than meteoroids.

Answer 2

A meteor is the streak of light when a rock falls from space and burns up in the Earth's atmosphere. An asteroid is a rock in space that's big enough to be detected in space before it hits the Earth's atmosphere.

There have only been a couple of times when astronomers have detected rocks in space that then hit the Earth's atmosphere and became meteors. Fortunately, there haven't been any big asteroids that have hit the Earth in the last couple of thousand years; if a big asteroid were to hit the Earth, it would cause mass extinctions of life on Earth, and probably the end of human civilization on this planet. Even relatively modest sized space rocks can cause enormous havoc.

Answer 3

Asteroids are larger than meteoroids. Asteroids are rocky and metallic objects that are larger than 10 meters in size, while meteoroids are smaller rocky or metallic fragments that are typically less than 10 meters in size.

Answer 4

Well let's put it this way thousands of meteoroids hit the Earth every year - and we don't know. If an asteroid hit the Earth - we would KNOW.

Answer 5

An asteroid is by far the largest.

Asteroids can be planetkillers, where as a meteoroid most often only make a shiny pathway through our atmosphere where it burns up.

Answer 6

Asteroids are larger. Meteoroids range in size from sand to boulders. Asteroids range in size from a few tens of feet to several hundred miles.

Answer 7

yes yes they are bigger
