Our solar system, which sporting activities a sun at the center with nine orbiting planets, is really large, yet in the range of the whole Milky way Galaxy, we room very tiny and most likely not clearly shows from various other galaxies.

You are watching: If earth was the size of a golf ball

The range of the solar system deserve to be scaled under to feet. As soon as talking come schoolchildren, I have students volunteer to stand for the sun and planets. A college student stands in the room hold a golf sphere suspended on a wire to represent the sun. Various other students standing surrounding represent the planets.

If the 1.68-inch-diameter golf sphere represents the sun’s diameter the 864 thousands miles, then the 93 million-mile distance from earth to the sunlight would equal about 15 feet. The college student representing the earth would have to hold a BB-sized Earth and stand around 15 feet away. Actually the BB is much too large to represent planet with this scale. Rather than speak millions of miles, solar system distances can be much much easier to understand if we convert distance come “astronomical units” or AUs. The typical distance from planet to the sunlight is thought about to it is in one AU.
