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.
