4. Earth is a very small but, to us, very important part of the universe. The Earth is so small compared to the universe that nobody can really comprehend it Earth in the Universe

5. If the Sun was a 10 inch basketball… The earth would be a 1/10 inch pinhead 89 feet from the Sun. The Moon would be a smaller pinhead only 3 inches from the Earth. Pluto, would be 2/3 of a mile away!

Now the closest star is 120 feet away!

8. Earth in the Universe If we take another big sep back and draw two dots only 1/25 of an inch apart representing the Sun and the nearest star (Alpha Centauri)… Then the Milky Way galaxy is 70 feet wide. The Sun is 20 feet from the center of the Milky Way. In the middle of the galaxy dots would be every 1/25 inch or so, millions of dots, each one a star much like our Sun.
