In Depth | Asteroids - NASA Solar System Exploration
25 Nov 2024 at 2:04pm
Asteroids, sometimes called minor planets, are rocky remnants left over from the early formation of our solar system about 4.6 billion years ago. The current known asteroid count is: . Most of this ancient space rubble can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt.

Our solar system?s small bodies ? asteroids, comets, and meteors ? pack big surprises. These chunks of rock, ice, and metal are leftovers from the formation of our solar system 4.6 billion years ago.

Our solar system consists of our star, the Sun, and everything bound to it by gravity ? the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

Asteroids are airless, miniature worlds. There are likely several million of them circling the Sun, but the confirmed count now stands at nearly 800,000. Some of them are solid, while others are more like clumps of loosely bound rubble. Many asteroids are irregularly shaped, like potatoes. Because they have little mass, asteroids have weak gravity.

Their non-random distribution seems to indicate that they are the result of low-energy impacts by carbon-bearing asteroids that delivered the darker material to Vesta and other impacts that melted Vesta?s surface, darkening the material there.

Meteors come from leftover comet particles and bits from broken asteroids. When comets come around the Sun, they leave a dusty trail behind them. Every year Earth passes through these debris trails, which allows the bits to collide with our atmosphere and disintegrate to create fiery and colorful streaks in the sky.
