- 3533 - SOLAR SYSTEM - Size of our Solar System. If you scale the Solar System size down to basketball size. What does it look like? The Earth is a pinhead in the Solar System that is 90 feet across.
--------------------- 3533 - SOLAR SYSTEM - Size of our Solar System
- The Moon is 239,000 miles away and it takes the Sun’s reflected light 1.3 seconds to reach us. Most people are surprised to learn that the Moon is 1/4th the size of the Earth. Its diameter is 2,160 miles. If the Earth were a basketball the Moon would be a tennis ball 25 feet away. (scale 1 to 50 million).
-
- Saturn is 840,000,000 miles away this month. It takes 75 minutes for its light to reach us. Saturn has a diameter of 75,000 miles. That is 9 1/2 times the size of the Earth. The diameter of Saturn’s rings is 170,000 miles. That is ¾ th the distance from the Earth to the Moon.
-
- If the Earth were a basketball Saturn’s rings would be 18 feet across and the planet would be 8 feet in diameter. If Saturn were a basketball Earth would be a large marble 1.75 miles away. On this scale Saturn’s rings would be 1/12th the thickness of a human hair.
-
- Our Sun is 865,000 miles in diameter, 109 times the size of the Earth. The Sun is 93,000,000 miles away and it takes over 8 minutes for the sunlight to reach us. If the Earth was a basketball the Sun would be the size of the basketball court and 2 miles away.
-
- If the Sun were a basketball the Earth would be the head of a pin, 1/8th inch, and 90 feet away. (scale 1 to 5.5 billion). To get out to Neptune the Solar System would be 1 mile across.
-
- The Earth a 1/8 inch pinhead. This pinhead included the most recent index of reviews in case anyone has a hankering for info on these questions. Just ax!
