| differential rotation | rotation | As an object rotates, different parts of it may move at different rates. The Galaxy rotates differentially. | |
| solar motion | length per unit time | peculiar velocity | The velocity of the Sun through space, relative to the local standard of rest. The solar motion is U = -9 kilometers per second, V = +12 kilometers per second, and W = +7 kilometers per second. | 
| solar rotation | length per unit time | differential rotation | Differential rotation, the equatorial rotation taking less time than the polar by up to 9.4 Earth-days. |
