What is asteroid belt?

In the Solar System, the asteroid belt consists of asteroids that are smaller than the planet, often inadequate to keep the spherical shape , whose orbital is mainly centered between Mars and orbit. Jupiter (between 2.3 and 3.3 AU from the Sun), and composed primarily of non-volatile minerals.

Gather asteroids forming asteroids belt. The main belt has thousands of asteroids larger than 1 km, and millions of tiny objects like dust. Despite such a large number, the total mass of the main belt is 1000 times smaller than Earth's mass. Asteroids with a diameter less than 500m are called meteorites . Meteors and dust can hit Earth's atmosphere and create meteor "rain" .

The main belt between the two orbits of Mars and Jupiter.

Asteroids can assemble into asteroid groups and asteroid families, based on their unique orbital properties. Asteroids' moons are orbiting asteroids larger than asteroids. They are not as distinctly distinguished as the moons of the planet, sometimes they are almost as large as the planets on the side.

There are many asteroids that interfere with gravity, especially from Jupiter, that have flown in a particularly disturbing orbit. Inside the Solar System is full of flying asteroids, many of which also cut the orbit of the inner planets. In particular, many asteroids are captured by Jupiter in its orbit, both in Jupiter's L4 or L5, called Troia asteroids, although the term Troia is also used for cottages. planets at Lagrange points of other planets.

Origin: Asteroids believed to be the remains of an Earth-like planet, or smaller, could not be combined since the Solar System was newly formed, due to the interference of gravity. from Jupiter.

Special asteroid: The largest asteroid, Ceres, has a diameter of about 1,000km, large enough to take a spherical shape, making it a possible planet.
