A minor planet is a general term for small-bodies in our solar system not classified as comets. Asteroids and trans-Neptunian objects are considered minor planets. These objects may also be called planetesimals.

The asteroids, or "minor planets," are small bodies, none of them larger than Earth's Moon, most of which orbit in a broad band called the asteroid belt between the orbits of Mars and Jupiter.
Asteroids are also known as planetoids or minor planets.
THE ASTEROID BELT
The asteroid belt is a doughnut-shaped concentration of asteroids orbiting the Sun between the orbits of Mars and Jupiter, closer to the orbit of Mars.
Because of their small size and large numbers relative to the nine major planets, asteroids are also called minor planets.
They are known as minor planets. Asteroids range in size from Ceres, which has a diameter of about 1000 km, down to the size of pebbles. Sixteen asteroids have a diameter of 240 km or greater.

8 AU's from the Sun, between Mars and Jupiter, the asteroids (sometimes called minor planets) were later discovered. The rule also holds for the seventh planet, Uranus, which lies at about 19 a.u. Bode's law fails for the eighth planet, Neptune.

This is why asteroids are also called Minor Planets. The vast majority of asteroids are found in the asteroid belt between the orbits of Mars and Jupiter. This gives them a typical distance from the Sun of about 2-3.5 A.U.
Some of them are larger and are called minor planets or planetoids. They may also be known as NEOs -- Near Earth Objects. Whatever they may be called, they have much to tell us about our solar system.

Asteroids are often referred to as minor planets or planetoids.
Karl Ludwig Hencke found Astraea in the gap in 1846, and someone found at least one more every year after that. Starting in 1866, the new terms asteroid and minor planet began to be used for the objects in the gap.
