Solar system scale from Huygens's 'Cosmotheoros' (1698). On a disc of the Sun, the six known planets are shown to scale in order of their distance from the Sun, from left to right: Saturn, Jupiter, Mars, Earth, Venus and Mercury. This work by Dutch astronomer Christiaan Huygens (1629-1695) described the planets of the solar system and his theories on the existence of extraterrestrial life on those planets. | |
