What are the characteristics of aristotle’s picture of the heavens?

Aristotle's picture of the heavens portrayed a collection of 55 dense spheres consisting of an incorruptible substance called "aether," comprising the sun, moon, planets, stars, and other celestial bodies that surrounded the spherical Earth.

The conception of the world by Aristotle focused on the notion of elements. He believed in four elements of the Earth: earth, air, fire and water. Those elements ' natural tendencies influenced planet Earth's nature.

Naturally the heaviest element, earth, moved to the center of the system accompanied by the second heaviest, water. The atmosphere consisted of dust, the third-lightest element, accompanied by a fire layer, the lightest element.

The spheres surrounding the Earth and the celestial bodies connected to it were constituted by a fifth element, the aether. The moon had the nearest ring, while the planets had the furthest sphere. Outside of the planetary system lies the "Prime Mover" sphere, which traveled at a steady angular velocity supplying the whole system with motion.

While modern science ultimately disproved Aristotle's geocentric view of the universe, from the 3rd century BC until the 16th century AD it remained the basic image of the cosmos, and it worked well for astronomers trying to predict planetary movement and celestial events.
