Asteroida

An asteroid is a minor planet an object larger than a meteoroid that is neither a planet nor an identified comet that orbits within the inner Solar System or is co-orbital with Jupiter Trojan asteroids. Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type carbonaceous, M-type metallic, or S-type silicaceous. The size and shape of

Asteroid, any of a host of small bodies, about 1,000 km 600 miles or less in diameter, that orbit the Sun primarily between the orbits of Mars and Jupiter in a nearly flat ring called the asteroid belt. Hundreds of thousands of asteroids are known.

Several hundred thousand asteroids have been discovered and given provisional designations so far. Thousands more are discovered each year.

Asteroids come in a variety of shapes and sizes and teach us about the formation of the solar system.

What is an Asteroid? Asteroids are small, rocky solar system bodies that populate interplanetary space out to the orbit of Jupiter. There are millions of

Asteroids are flying space rocks occasionally featured in sci-fi movies and perhaps in our low-level fears of going the way of the dinosaurs. But just what are these potato-shaped chunks of rock
