Asteroids are small irregularly shaped bodies, sometimes called minor planets, which orbit the sun, and are most frequently found between which two planets?

The vast majority of our solar system's asteroids are found in a wide, doughnut-shaped region known as the main asteroid belt. This cosmic junkyard occupies the enormous orbital gap between the fourth planet, Mars, and the fifth planet, the gas giant Jupiter. The reason for this specific location is the immense gravitational influence of Jupiter itself. Early in the solar system's formation, Jupiter's powerful gravity constantly stirred up the rocky debris in this zone, preventing it from ever coalescing into a single, large planet. Instead, the material was sent into frequent collisions, creating the millions of smaller, irregularly shaped bodies we see today.

These asteroids are essentially leftover building blocks from the dawn of our solar system over 4.5 billion years ago. While movies often depict the belt as a dense field of tumbling rocks, it is actually mostly empty space. The asteroids are spread out over such a vast area that a spacecraft could fly through it with an extremely low chance of an accidental collision. This region is home to countless objects, ranging from dust-sized particles to the largest resident, the dwarf planet Ceres, which is nearly 600 miles in diameter.
