A Journey Through Our Solar System
You are standing near the Sun within a model of our solar system. The real solar system is 10 billion times larger.
Take a voyage! Imagine exploring our solar system as a giant. As you travel, you encounter the Sun and its planets, each small enough to hold in your hand. To your left you can see the Sun and inner planets. The dwarf planet Pluto is farther still. Look at the map below to see where you are.
Would you like to visit Proxima Centauri, the nearest star to the Sun? At this scale it would be the size of a grape on the coast of California, 2,500 miles (4,000 km) from where you are standing.
Our Star the Sun
Imagine the view from space. Countless points of brilliant light shine against an ink-black sky. Because it is so close, one star seems blinding and immense--our Sun.
Planets and Empty Space
The Sun's family of planets is spread across a vast and mostly empty space. This scale model of our solar system provides a feel for just how vast and empty it is. The planets of the inner solar system--Mercury, Venus, Earth, and Mars--are clustered close to the Sun. The outer planets--Jupiter, Saturn, Uranus, and Neptune--are spread much farther apart.
The Sun's Family
Think of our solar system as the Sun's family. Along with earth and the other
To see a World in a Grain of Sand
And a Heaven in a Wild Flower
Hold Infinity in the palm of your hand
And Eternity in an hour
William Blake, Auguries of Innocence, 1803.
More than one million Earths fit inside the Sun. More than 800 million Suns fit inside the star Betelgeuse.
Voyage is an exhibition of the National Center for Earth and Space Science Education and the Smithsonian Institution. It is designed for permanent installation in communities worldwide.
A 2013 update of this exhibition's content is provided by a grant from the DC Space Grant Consortium.
Initial development and installation of the exhibition in Washington, DC, was a joint project of Challenger Center for a Space Science Education, the Smithsonian Institution, and NASA.
