Diameter of planets and their distance from the Sun in kilometers (km):
16 lis 2018 · For comparison the Earth’s orbit is much more circular and its distance from the Sun varies by less than 2m in our scale model. Much smaller than the Earth, Mars comes in at just 2.7mm. Notice how in moving from the Earth to Mars we increased the size of the Solar System by over 50%.
Real and Scaled Distances of the Planets. The scale factor is 1 to 10 billion. Every meter in this scale model solar system represents 10 billion meters in the real solar system.
See how the sizes of planets and the distances between them compare. And find out why it's so hard to create a scale model of the solar system that accurately represents both size and distance on a single screen or the page of a book.
See how large the planets appear in the sky. For local times and where to look etc., try the night sky in your location. The planets' apparent size is measured in arcseconds ("). For comparison, the Sun and the Moon measure about 1800 arcseconds.
