AnswersDriveThe Asteroid Belt is located in an area of space between the orbits of Mars and Jupiter. That places it between 2.2 and 3.2 astronomical units (AU) from the Sun. The belt is about 1 AU thick. The average distance between objects in the Asteroid Belt is quite large.
Who discovered the asteroid belt?
In 1801, while making a star map, Italian priest and astronomer Giuseppe Piazzi accidentally discovered the first and largest asteroid, Ceres, orbiting between Mars and Jupiter.
Why is it called the asteroid belt?
The dwarf planet called Ceres orbits the Sun in the asteroid belt. An asteroid is a bit of rock. It can be thought of as what was "left over" after the Sun and all the planets were formed. Most of the asteroids in our solar system can be found orbiting the Sun between the orbits of Mars and Jupiter.

How long does it take an asteroid in the asteroid belt to orbit the sun?
Many asteroids orbit the Sun in a region between Mars and Jupiter. This "belt" of asteroids follows a slightly elliptical path as it orbits the Sun in the same direction as the planets. It takes anywhere from three to six Earth years for a complete revolution around the Sun.

How big is the asteroid belt in KM?
Because the asteroid belt is between the Mars and Jupiter orbits, it is around 2.2 to 3.2 Astronomical Units (AU) from the Sun – which is approximately 329,115,316 to 478,713,186 km. The average distance between objects is a massive 600,000 miles.
3
Which planets have the most rings?
All of the giant planets in our solar system have rings: Jupiter, Saturn, Uranus, and Neptune. Jupiter's ring is thin and dark, and cannot be seen from Earth. Saturn's rings are the most magnificent; they are bright, wide, and colorful.
4
Which is the largest inner planet?
Earth is the third inner planet and the one we know best. Of the four terrestrial planets, Earth is the largest, and the only one that currently has liquid water, which is necessary for life as we know it.
5
Which is an inner planet?
The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune. The interesting thing is, in some other planetary systems discovered, the gas giants are actually quite close to the sun.
6
How does Earth's atmosphere help it to sustain life?
The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. A thin layer of gas called ozone high up in the atmosphere filters out these dangerous rays. The atmosphere also helps to sustain life of Earth.

How many asteroids are there in the universe?
As far as how many asteroids there are… well, if you only consider those larger than 100 meters orbiting within the inner Solar System, there's over 150 million. Count smaller ones and you get even more.
9
What asteroids are made of?
Asteroids are made of rock, metals and other elements. Some even contain water, astronomers say. Asteroids that are mostly stone sometimes are more like loose piles of rubble. Asteroids that are mostly iron are more, well, rock-solid.
11
Where is the asteroid belt in our solar system?
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
12
What is the difference between a meteor and a meteorite?
Most of us probably have seen meteors or shooting stars. A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris burns up as it passes through our atmosphere. If any part of a meteoroid survives the fall through the atmosphere and lands on Earth, it is called a meteorite.
13
Do comets revolve around the sun?
Comets contain dust, ice, carbon dioxide, ammonia, methane and more. Comets orbit the sun, but most are believed to inhabit in an area known as the Oort Cloud, far beyond the orbit of Pluto. Occasionally a comet streaks through the inner solar system; some do so regularly, some only once every few centuries.
14
How far away is the asteroid belt?
The belt's inner edge is about 30 astronomical units (AU) away from the Sun. Its outer edge is about 50 AU away from the Sun. One AU is equal to the average distance between Earth and the Sun, or about 150 million km (93 million miles).
15
Where is the Oort cloud in the solar system?
The two regions vary primarily in terms of distance and location. The Kuiper Belt orbits in approximately the same plane as the planets, ranging from 30 to 50 times as far from the Sun as Earth. But the Oort Cloud is a shell that surrounds the entire solar system, and is a hundred times as distant.
16
What separates the inner and outer planets?
Next come Mercury, Venus, Earth, and Mars. After Mars, there is an asteroid belt that separates the inner planets from the outer ones. The outer planets are called the jovian planets, meaning huge gas giant. These planets in order are Jupiter, Saturn, Uranus, and Neptune.
17
Where do comets come from?
Short-period comets (those which take less than 200 years to complete an orbit around the Sun) originate from the Kuiper Belt. Danish astronomer Jan Oort proposed that comets reside in a huge cloud at the outer reaches of the solar system, far beyond the orbit of Pluto. This has come to be known as the Oort Cloud.
18
What is not a planet anymore?
According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit. Pluto has been demoted because it does not dominate its neighborhood.
19
Where would you find the asteroid belt?
The asteroid belt is a region of space between the orbits of Mars and Jupiter where most of the asteroids in our Solar System are found orbiting the Sun. The asteroid belt probably contains millions of asteroids.
20
How many planets have rings around them?
Four the planets in the Solar System have rings. They are the four giant gas planets Jupiter, Saturn, Uranus, and Neptune. Saturn, which has by far the largest ring system, was known to have rings for a long time. It was not until the 1970s that rings were discovered around the other gas planets.
