The bodies that revolve around the Sun is termed as asteroid. They are very massive and have an irregular shape, but they cannot produce gravitational force as they are comparatively smaller than that of the Sun and other planets. The texture of asteroid is rocky or metallic, and they also revolve around other planets (like Jupiter). Also, they can revolve in orbit or without orbit. An example of the asteroid is a meteor
						

							
The ball that consists of dust and ice and moves in the space is termed as a comet. The nucleus of the comet made up of ice, and they have a tail of gas and dust that points away from the sun while revolving around the sun as they live in the solar system. Methane, carbon dioxide, and ammonia are also the constituent parts of the comet. Hale Bopp is the example of the comet
						

							
The planet-like body that revolves around the sun but is not exactly the planet is known as a dwarf planet. They have their orbit for the revolution. Based on the mass of the dwarf planet, it has its gravitational force, and with the help of that, it can attract some bodies in space. Its shape is approximately spherical. The area around the dwarf planet is not clear around its orbit that makes stops it to come in the category of planets.
						

							
The angular acceleration of a body is opposed by a special quantity termed as a moment of inertia. Moment of inertia is based on the mass of all the components of the body individually. It can be determined by adding the multiplication of the distance between the rotational axis and the component and individual mass of components. Different shapes have different values of the moment of inertia. 
						

							
The proportion of an item or size of a body is termed as its dimension. It can be for any shape and multi-dimensional (one-dimensional, two-dimensional, or three-dimensional). By measuring shapes, different dimensions can be obtained that are breadth, length, height, etc. Area, volume, density, and many other quantities can be calculated with the help of dimensions. It is the basic measure of all shapes.
