The most obvious comparison would be the differences in their physical sizes. Because the diameter of the sun is about 100 times that of the Earth, its volume is 100^3 or one million times that of the Earth. Tied in with that is the much greater mass of the sun, which in turn leads to the second comparison, that of its force of gravity and influence over other celestial objects. The Earth's force of gravity is much smaller than that of the sun, and influences (mainly) only the Moon and man-made satellites and spacecraft in its immediate vicinity. The Sun's large force of gravity is what keeps all nine planets and their many moons in orbit, along with numerous asteroids, comets, and meteoroids (which from time to time are pulled out of their orbits by that gravitational force).

To make an impact, use examples with visual content. As in the following.
Example 1: If the Sun were the size of a foot ball (in soccer), the Earth would be the size of the head of a pin (with Jupiter the size of a table tennis ball!)
Example 2: How many Earths would fit inside the Sun? Answer: 1,000,000! You can illustrate this with a fish bowl (as the Sun) and a marble (as the Earth). 1 million marbles would fit inside the fish bowl.

Two different manners may be found by means of understanding the force of gravity. The first is that of the gravitational attraction at the surface of the sun is which is 28 times greater than the gravitational attraction for us who are on the surface of our planet. The second is that the sun expends 665 lbs./sec equivalent mass in order to keep the planets in place whereas our planet expends 0.00444 kg./sec keeping things here operating. A third, if you wish, is that there is an area within the center of our sun where a mass is unable to exist due to mass acceleration to to gravity attraction, this is an area within our sun that is 800 miles across. Within our own planet this area is just under one and one-half miles in diameter.

By comparing the angle subtended by them at a given point in space.

size and weight. It's about 1.3 million times as big, but only 320,000 times as heavy.
