The distances between inner planets (Mercury, Venus, Earth, Mars) are much smaller compared to the distances between outer planets (Jupiter, Saturn, Uranus, Neptune). The inner planets are closer to each other, with relatively small gaps between their orbits, while the outer planets are much farther apart, with larger gaps between their orbits.
The inner planets (Mercury, Venus, Earth, Mars) are separated from the outer planets (Jupiter, Saturn, Uranus, Neptune) by the asteroid belt, a region of space located between the orbits of Mars and Jupiter. The asteroid belt contains millions of rocky objects that range in size from small boulders to dwarf planets.
It sounds like you are describing an asteroid, which is a small rocky body that orbits the sun. Asteroids are most commonly found in the asteroid belt between Mars and Jupiter, but they can exist in various other regions of the solar system as well.
It may be a bit of an exaggeration to talk about an "asteroid belt", as if it were something solid. It isn't. The asteroid belt is predominantly empty space. However, there is a broad region between Mars and Jupiter which are somewhat less empty than the space elsewhere. It's a BIG area, thinly populated with some fairly big rocks. The largest is the asteroid Ceres, which was reclassified 4 years ago as a "dwarf planet. and two additional objects - Vesta and Pallas - may be reclassified as dwarf planets in the future. The total mass of all the asteroids together is somewhat less than the mass of Earth's Moon.
There is no "small dense object" that orbits between Mars and Jupiter. There are however numerous asteroids which are rocky objects up to a few hundred miles in diameter that orbit in this region making up what is called the asteroid belt.
Asteroids
Technically speaking, the asteroid belt doesn't "run through" any planets but between two planets. As such, the asteroid belt is located between the orbits of Mars and Jupiter.
The asteroid belt is found between the orbits of Mars and Jupiter.
Asteroids
The asteroid belt lies between the orbits of Mars and Jupiter.
The distances between the orbits of the inner planets (Mercury, Venus, Earth, and Mars) are relatively small compared to those of the outer planets (Jupiter, Saturn, Uranus, and Neptune). The inner planets are closely spaced, with smaller gaps between their orbits, while the outer planets have much larger distances between them due to the exponential increase in orbital radius as one moves away from the Sun. This pattern reflects the differing formation processes and gravitational influences in the solar system.

The asteroid belt contains millions of rocky objects that range in size from small boulders to dwarf planets.
The asteroid belt, which consists of millions of individual asteroids of varying sizes - from a speck of dust to hundreds of kilometres in diameter - is located between the orbits of Mars and Jupiter. It therefore separates the inner (or rocky) planets from outer (or gas giant) planets.
If by small bodies you mean planets, then Jupiter is the answer you want. If you mean dwarf planets, then you are looking for Ceres in the asteroid belt between Jupiter and Mars.
Most of the asteroids within our solar system can be found within the Asteroid Belt. Located between the orbits of Mars and Jupiter, the Asteroid Belt consists of millions of individual asteroids of varying sizes - from a speck of dust to hundreds of kilometers in diameter. The largest object within the belt is a dwarf planet - Ceres - which has a mass of 9.47x1020kg and a diameter of 476.2km.
