solar motion
subject			fact

solar motion	has definition 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.
	is a kind of mass motion
	is a kind of peculiar velocity
velocity	has base unit length per unit time
physical process	has domain physics
quantity	has unit
number	has value

Kinds of solar motion :

• Evershed effect (2 facts) - The radial motion outward (from the central umbra) of the gases in the penumbral regions of sunspots.
• five-minute oscillations (3 facts) - Vertical oscillations of the solar atmosphere with a well-defined period of 5 minutes.
• solar rotation (3 facts) - Differential rotation, the equatorial rotation taking less time than the polar by up to 9.4 Earth-days.
• Sporer's law of zones (2 facts) - The equatorward drift of average sunspot latitudes.
