This is a montage of planetary images taken by spacecraft managed by the Jet Propulsion Laboratory in Pasadena, CA. Included are (from top to bottom) images of Mercury, Venus, Earth (and Moon), Mars, Jupiter, Saturn, Uranus and Neptune. The spacecraft responsible for these images are as follows:
Pluto is not shown as no spacecraft has yet visited it. The montage was created soon after Voyager 2's historic encounter with Neptune in August 1989 and thus takes the perspective of looking back from Neptune (in the foreground) toward the Earth. The inner planets (Mercury, Venus, Earth, Moon, and Mars) are roughly to scale to each other; the outer planets (Jupiter, Saturn, Uranus, and Neptune) are roughly to scale to each other, with the exception of Neptune, which as a foreground object, is shown larger. PIA01341 is the same montage with Neptune shown more to scale. Actual diameters are given below:

Photojournal Note: In 2006 the International Astronomical Union (IA) reclassified Pluto as a dwarf planet. Pluto is no longer considered the ninth planet of our solar system.
