The planets can also be distinguished from fixed stars because stars tend to twinkle, while planets appear to shine with a steady light.
For a terrestrial planet, the contrast ratio of planet to its host stars is approximately ~10 −6-10 −7 in the thermal infrared or ~10 −9-10 −10 in the optical/near infrared. For this reason, Darwin and Terrestrial Planet Finder-I will work in the thermal infrared.
Map of the Planet Walk. The Sciencenter's Sagan Planet Walk is a walkable scale model of the Solar System, located in Ithaca, New York. The model scales the entire Solar System—both planet size and distances between them—down to one five billionth of its actual size.
