Solar System in Perspective

NASA/JPL-Caltech

This artist's concept puts solar system distances in perspective. The scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance. One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is about 30 AU. NASA's Voyager 1, humankind's most distant spacecraft, is around 125 AU. Scientists believe it entered interstellar space, or the space between stars, on Aug. 25, 2012. Image released Sept. 12, 2013.

Moving into Interstellar Space

NASA/JPL-Caltech

This artist's concept shows the outer layers of our solar bubble, or heliosphere, and nearby interstellar space. NASA's Voyager 1 is currently exploring a region of interstellar space, which is the space between stars that still feels charged particle and magnetic field influences from the heliosphere. The magnetic field lines (yellow arcs) appear to lie in the same general direction as the magnetic field lines emanating from our sun. Image released Sept. 12, 2013.
