All right. Differences with the Historical Model: 1. That model shows the planet's orbits as perfect circles, not ellipses. <span>2. Aristotle believed in a geocentric (Earth centered) solar system, while it actually is heliocentric Sun centered). </span> <span>3. That model didn't show all the planets we know today, such as Neptune, Uranus, etc. </span> <span>4. A lot of that model was based on religious beliefs. </span>Differences with Modern Model: 1. Our model shows the orbits as ellipses. <span>2. Our model shows a heliocentric solar system. </span> <span>3. Our model shows all the planets we know today. </span> <span>4. Our model has nothing to do with religion. </span>Similarities Between Both Models: 1. They both are based on the same solar system. <span>2. They both show the inner planets, the Moon, the Sun, Jupiter, and Saturn. </span> <span>3. The both were made by many observations of the sky. </span> Hope this helps.:b
