Our solar system is mostly the sun. Not in area, perhaps: Measured to its ultimate boundary, the region suffused by solar energy may be 46 billion kilometers (30 billion miles) across, while the diameter of the star itself is just 1.4 million kilometers (865,000 miles). But the sun accounts for about 99.9 percent of the solar system's mass. Everything else - the planets, asteroids, meteoroids, comets, and floating dust and gas - could be considered leftovers from the formation of a medium-size star about 4.6 billion years ago.

Explore the sun's neighborhood - with this information-packed map of our solar system! Featuring details on all eight planets and other celestial bodies that impact orbits and the very way that the system functions, this map takes its readers on a celestial journey that provides insight into the reasons why everything is the way it is. The planets are displayed in relative sizes to truly demonstrate the sheer size of the solar system we call home.

This map is an attractive product for the budding astronomer. It makes an essential companion to Milky Way: Earth's Galactic Home, and its size makes it perfect for a gallery wall.

This map is found in National Geographic's 11th Edition World Atlas and is now available as a stand alone product.
