Most asteroids are rocky bodies that orbit the Sun between Mars and Jupiter in a "Main Asteroid Belt" that is centered around 2.7 times the Earth-Sun distance (astronomical unit or AU) from Sol.

The main asteroid belt extends from 2.15 to 3.3 astronomical units (255 to 600 million km) from the Sun – between Mars (1.5 AU) and Jupiter (5.2 AU) – and may contain over a million objects bigger than 1 km across, the largest being Ceres (1,003 km), Pallas (608 km), and Vesta (538 km). Within the belt,

Main Belt: Most minor planets orbit the Sun in the main asteroid belt, a vast ring of hundreds of thousands of rocky objects circling between the orbits of Mars and Jupiter, from 2 to 4 AU from the Sun. These objects are believed to be leftover fragments from the formation of the solar system about 4.6 billion years ago.

In many science-fiction movies, the asteroid belt is like a cosmic obstacle course, but the truth is far less dramatic: The asteroids are so widely separated that it's easy for a spacecraft to maneuver through the belt without even seeing an asteroid, much less running into one.
