Space-age view of the planets

Space-age view of the planets

. A montage of planetary images taken with different spacecraft and presented, from top to bottom, in order of increasing distance from the Sun. They are Mercury (top) taken from Mariner 10, a Venus image from Magellan, the Earth seen by Galileo, with our Moon, a Viking mosaic image of Mars, Voyager 1 images of Jupiter and Saturn, and Voyager 2 views of Uranus and Neptune (bottom). The inner planets, closest to the Sun (Mercury, Venus, Earth and Mars) are roughly to scale to each other, and the outer planets, furthest from the Sun (Jupiter, Saturn, Uranus and Neptune) are also shown roughly to scale to each other.
