Final answer:
The asteroid belt is the region between Mars and Jupiter where most asteroids in our solar system are found, characterized by wide spacing between individual asteroids.
Step-by-step explanation:
The group of asteroids that orbits between Mars and Jupiter is called the asteroid belt. This region contains the majority of asteroids in our solar system, with orbital periods ranging from 3.3 to 6 years. These asteroids revolve around the Sun in the same direction as the planets, and their orbits are generally aligned with the plane in which Earth and the other planets circulate. The asteroid belt is located between 2.2 and 3.3 astronomical units (AU) from the Sun. Despite being numerous, the asteroids within the belt are not densely packed; there is a vast amount of space between them, with the typical spacing between objects being several million kilometers. This sparse distribution has facilitated the passage of spacecraft through the asteroid belt without the risk of collision.
