    * Astronomers today do not use (term) to refer to the turning of an object about an axis: they use (rotation) for that, and (term) only for the traversal of a body through an orbit (which also happens around some axis). (This may be somewhat customary, however, strictly speaking, using either word for either process would not be incorrect.)
