Across the equator

142,984 km

Average distance from the Sun

5.203 AU (about 778 million km)

One trip round the Sun

11.9 Earth years

One spin on its axis

9 hours 56 minutes. The fastest spin of any planet.

Moons

many known; the four largest are Io, Europa, Ganymede and Callisto

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).
