Solar System Montage
Date: 1 Jan 1998
This is a montage of images taken by spacecraft. Included are (from top to bottom) Mercury, Venus, Earth (and Moon), Mars, Jupiter, Saturn, Uranus and Neptune. The spacecraft responsible for these images are as follows:
* Mercury was photographed by Mariner 10.
* Venus was imaged by the Magellan spacecraft's radar.
* Earth and its Moon were photographed by Galileo.
* Mars Global Surveyor took the image of Mars.
* Jupiter was photographed by Cassini as it traveled to Saturn.
* Saturn, Uranus and Neptune images were taken by the twin Voyager spacecraft.
* Pluto is not shown. No spacecraft has visited Pluto and it is too small and distant for good photography.
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. But the actual size differences between the inner and outer planets is not to scale. Image Credit: NASA/JPL.
