This 2D visual model illustrates the scale of the sun and planets in our solar system, and their current distance from each other.

The best way to understand the true dimensions of the solar system is to create a scale model. Use the tool below to visualize the solar system at various scales. Choose the size of the Sun you want in your model in STEP 1. The dimensions of the other objects and their distances will be calculated automatically.

Solar System to Scale Sun is scaled one meter (39") in diameter Actual Size of Sun: 1,391,000 km (864,000 mi) AU (“Astronomical Unit”) is the average distance between the Sun and Earth: 150 million km (93 million mi) A little more than 100 Sun diameters will span the distance of one AU Neptune Actual Size: 49,500 km (30,800 mi) diameter

Make a scale model of the Solar System and learn the REAL definition of "space." © 1997 Ron Hipschman. Fill in the diameter of the Sun you want your model to be scaled by. You can fill in either the red bordered inches box or the green bordered …

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.

Make a scale model of the Solar System and learn the REAL definition of "space." This Page requires a JavaScript capable browser. Fill in the diameter of the Sun you want your model to be scaled by.

planet sizes to scale, the paper would need to be way too large to show the scaled distances. Instead, to help you understand the sizes and distances of our solar system, we’ve created a scale model. Our Solar System, real imagery but not to scale

The Colorado Scale Model Solar System depicts the Sun, the planets, and the distances between them all on the same scale of 1 to 10 billion. That is, the real objects and distances are 10 billion times larger than the objects and distances in the model.

Solar Scroller is a travel-able to-scale and accurately animated model of our solar system. Built with HTML5 and PHP, some of the most complex CSS3 animations, and powered by a completely custom jquery library - Solar Scoller not only shows the wonders of our solar system but the possibilities of CSS.

This page shows a scale model of the solar system, shrunken down to the point where the Sun, normally more than eight hundred thousand miles across, is the size you see it here. The planets are shown in corresponding scale.
