How do I calculate scaled planet diameters & planet-Sun distances?

Calculate the scaled planet diameters and planet-sun distances for a solar system model. Enter scale or diameter or distance, select to show table and/or map below, select options, then press Calculate. Please enter scale or diameter or distance from sun. Orbits of objects beyond Neptune are highly eccentric ellipses, not circles. Map not shown.

How do I build a solar system model?

To construct a solar system model, enter 5 (for example) in the scale factor box, click "Earth diameter" and you will have all the dimensions in terms of the Earth's diameter.

How big is a solar system?

Instead, let's try a solar system in which the Sun's diameter equals 5 inches, which means the Earth is 0.045746 inches (about 1.1 mm) wide and the Earth Sun distance would be 537.09 inches (roughly 45 feet). Do you see how difficult it is to construct a solar system model?

How long is a solar system based on a scale?

When a scale is entered, the sizes with the matching units will be shown. A common scale for realizing a complete model of the solar system in the field is one to 500 million. Then the whole system has a length of 9 to 12 kilometers, depending on whether Pluto is included or not.

How long is a solar system?

A common scale for realizing a complete model of the solar system in the field is one to 500 million. Then the whole system has a length of 9 to 12 kilometers, depending on whether Pluto is included or not. * for moons, the distance is not to the Sun, but to their planet. Round to decimal places.

What if a solar system has a 5 inch Earth?

So, a solar system with a 5 inch Earth would have a Sun that is (look at the calculations) 546.49 inches (45.5 feet) in diameter and the Earth to Sun distance would be 58,703 inches (4,892 feet) - almost a mile!
