to explain the motion of planets, especially the phenomenon of retrograde motion where planets appear to temporarily reverse their direction of motion. Ref: Andrew Liddle "An Introduction to modern Cosmology".

Are the inner planets smaller than the outer planets?
yes the inner planets are much smaller then the outer planets
Is mass larger on bidder planets or smaller?
Mass does not change with gravity. Weight increases on BIGGER planets and decreases on smaller planets.
The planets look smaller than the sun because they are further away?
The planets are smaller than the sun.
Are the inner planets smaller then the outer planets?
Yes. The inner planets are Mercury, Venus, Earth, and Mars, and they are smaller than the outer planets: Jupiter, Saturn, Uranus, and Neptune.
Do the planets look smaller than the sun because they are further away?
No. Planets look smaller than the sun because they actually are smaller.
What was Ptolemy trying to explain in his model by haven't the planets move on smaller circles that move big circles?
ptolemy did something
What was Ptolemy trying to explain in his model by having the planets move on smaller circles that move on the bigger circles?
Ptolemy is trying to explain in his model that each circle represents 1 planet's rotation and it's a scale drawing of the distance apart from each one!

What planet circles the sun faster than any other planets?
Mercury circles the sun in 88 days. That is the fastest orbiting planet. It is because of it's position with the sun. It is the closest so it has a smaller orbit.
Are the inner planets smaller than the outer planets?
yes the inner planets are much smaller then the outer planets
Are the rockey planets larger or smaller than the gas planets?
smaller
Are gas planets smaller than dwarf planets?
No. All of the objects in out solar system labeled as dwarf planets are smaller than the smallest of the planets. The gas planets are the largest planets.
What the asteroids are larger or smaller than planets?
are asteroids smaller or larger than planets
What are the tiny planets?
Objects that are smaller than planets are called "dwarf planets"; even smaller objects are called "asteroids".
Would a small circles chord be smaller than a big circles chord?
yes because one is smaller than the other
Is mass larger on bidder planets or smaller?
Mass does not change with gravity. Weight increases on BIGGER planets and decreases on smaller planets.
Are dwarf planets smaller than inner planets?
Yes, all of the dwarf planets are smaller than the smallest inner planet (Mercury).
