Planets and dwarf planets

Each page has the real numbers and a link that flies you there on the map.

• Mercury The smallest planet and the closest to the Sun, with almost no atmosphere.
• Venus About Earth's size, wrapped in thick cloud, with a surface hot enough to melt lead.
• Mars A cold desert world with the tallest volcano in the Solar System.
• Jupiter The largest planet: a gas giant more massive than all the other planets together.
• Saturn The ringed planet, light enough that it would float in water if there were an ocean big enough.
• Uranus An ice giant tipped on its side.
• Neptune The farthest planet from the Sun, a deep-blue ice giant.
• Ceres The largest object in the asteroid belt, a dwarf planet.
• Pluto A dwarf planet in the Kuiper belt, visited by New Horizons in 2015.

Equatorial diameters (the same values the map draws) and spin: NASA NSSDC planetary fact sheets (https://nssdc.gsfc.nasa.gov/planetary/factsheet/). Mean distance from the Sun: JPL Approximate Positions of the Planets, Table 1, and the JPL Small-Body Database for Ceres and Pluto. Year length is computed from the distance with Kepler's third law (years = distance in AU to the power 1.5).
