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. Instructions

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.

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

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

This page displays the sun and all the planets in a proper relative scale and distance, so you can experience how vast our solar system is just by scrolling. How far can you reach? Let's find out.

Make a scale model of the Solar System and learn the REAL definition of "space."

2024年10月1日 · In this project, you will create your own scale model of the solar system by learning how to calculate scale distances, the relative sizes of planets, or both. Then, use beads and string, sidewalk chalk, or your own creative choice of materials to build a model you can explore – or maybe even wear!

2023年4月19日 · In this section of the Year of the Solar System guide, the nine sets of problems call for students to use proportions, unit multipliers, scientific notation, and geometry to determine travel times to the planets and calculate distances and sizes of planets.

Purpose: Construct a scale model of the solar system to familiarize the student with the relative sizes and positions of the planets in the solar system and the vast distances between them and between the Sun and other stars.

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.
