## What if the Sun was the size of a soccer ball?

It’s hard to visualize that kind of distance, so engineer Mark Rober made a video to help us out. If you use a football field as a scale for the solar system, then the sun would be about the size of a soccer ball on the goal line. Earth would be 26 yards away and only the size of a pinhead.

How big would the Sun be if the Earth was the size of a golf ball?

We have taken our earth to be of the size of a golf ball. At this scale, the Sun would be over 15 feet wide and we would be able to fit 1.3 million golf ball-sized earths inside of it.

How big would the moon be if the Earth was a tennis ball?

On average, the moon is 384,403 km away from the Earth, which is just over 2 meters in our new scale (the height of a door). So, if we shrank the Earth to the size of a tennis ball, the moon would be the size of a marble a door’s length away. That’s a lot of space inbetween!

### Does the size of a soccer ball affect how far it goes?

When two balls of the same diameter are made of materials of different density and mass, the ball with the greater mass-density will travel farther if projected with the same amount of force, or at the same initial speed.

How far away is the 9th planet from the sun?

Planet Nine was initially hypothesized to follow an elliptical orbit around the Sun with an eccentricity of 0.2 to 0.5, and its semi-major axis was estimated to be 400 to 800 AU, roughly 13 to 26 times the distance from Neptune to the Sun.

What if the Earth was as big as the Sun?

If our world was as big as the Sun, then, like the water, our soil would have to be spread out to cover a much larger space. With the Earth as big as the Sun, you’d pretty much lose the Moon either way. But if a planet has more mass, it will also have a stronger gravitational pull.

#### What if the Earth was the size of a basketball?

If you shrunk the Earth to the size of a basketball (11.8 inches in diameter, or just under a foot) while keeping the Solar System to scale, then the Sun would be a ball 107 feet in diameter while Ceres, the largest asteroid, would be golf-ball sized.

Why does the size of a soccer ball matter?

Sure, there are countless colors and a multitude of materials available, but one of the largest areas of difference among soccer balls is sizing. This variation serves a purpose, though, as it allows more individuals to experience the game with the same amount of fun and excitement.

Does size affect speed?

Our results show that the size of an object affects the perception of its speed. In particular, smaller objects appeared to move faster in translational motion.
