The sun and planet gear converted the vertical motion of a beam, driven by a steam engine, into circular motion using a 'planet', a cogwheel fixed at the end of the connecting rod (connected to the beam) of the engine. With the motion of the beam, this revolved around, and turned, the 'sun', a second rotating cog fixed to the drive shaft, thus ...
This planetary gear train consists of a sun gear (yellow), planet gears (blue) and carrier (green) inside a ring gear (red) An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun").
The inner planets couple with the small sun gear and co-rotate at a fixed gear ratio with respect to it. The outer planets couple with the large sun gear and co-rotates with a fixed gear ratio with respect to it. Finally, the ring gear also couples and co-rotates with the outer planets in a fixed gear ratio with respect to them.
Simpson Planetary Gearset Schematic Diagram. The two planetaries are interdependent via two permanent connections, that commonly but not necessarily have the same gears and gear ratios, both gearsets share a common sun gear. The planet carrier of the first gearset ("first" means closer to the input shaft) is in synchrony with the second gearset ...

The left sun gear (red) provides more resistance than the right sun gear (yellow), which causes the planet gear (green) to rotate anti-clockwise. This produces slower rotation in the left sun gear and faster rotation in the right sun gear, resulting in the car's right wheel turning faster (and thus travelling farther) than the left wheel.

Antikythera mechanism, main fragment, c. 205 to 87 BC Carlo G Croce, reconstruction of Dondi's Astrarium, originally built between 1348 and 1364 in Padua. The Antikythera mechanism, discovered in 1901 in a wreck off the Greek island of Antikythera in the Mediterranean Sea, exhibited the diurnal motions of the Sun, Moon, and the five planets known to the ancient Greeks.
