If a rocky object is orbiting the Sun between the terrestrial planets and Jovian planets, in a near circular orbit, hasn’t cleared its path, and isn’t spherical, how can it be categorized?

Rephrasing the question and options helps set the stage: we’re looking for the category that fits a rocky object orbiting the Sun, between the terrestrial and Jovian planets, in a near circular orbit, that has not cleared its path and is not spherical. 
Option 1: Moon. This is a natural satellite, not a body orbiting the Sun independently. It orbits a planet, so it would not be described as an object orbiting the Sun between the planets. Therefore this is not a good fit.
Option 2: Comet. Comets are icy bodies that typically have highly elliptical orbits and develop comas and tails when near the Sun. Their orbits are not generally near circular, and the key clues here emphasize a near circular orbit and not having cleared the path, which leans away from comets and toward a different category.
Option 3: Terrestrial planet. Terrestrial planets are large, rocky planets that have cleared their orbital zones and tend toward hydrostatic equilibrium, giving them a roughly spherical shape. The statement specifies it has not cleared its orbit and is not spherical, which contradicts the defining features of terrestrial planets.
Option 4: Asteroid. Asteroids are rocky bodies that orbit the Sun, commonly found between the terrestrial and Jovian planets (notably in the asteroid belt). Many asteroids have non-spherical shapes and have not cleared their orbital paths, aligning well with the description given in the question.
Option 5: Dwarf planet. Dwarf planets are objects that orbit the Sun and are massive enough to be nearly spherical but have not cleared their orbits. The prompt states the object isn’t spherical, which contradicts the defining criterion for a dwarf planet.
In sum, the combination of orbiting the Sun between planets, being rocky, not clearing the orbit, and not being spherical best matches the category of an asteroid, while the other options conflict with one or more of these key criteria.
