Evidently, "The Solar System comprises the Sun and the objects that orbit it," including planet earth. If this is true, then, it is erroneous to describe what happens in the morning and evening as "sunrise" and "sunset" respectively. Since the Sun is stationary, it can neither rise nor set. Rather, it's earth and its inhabitants that actually rise and set on the sun. They were made up and became part of our accepted vocabulary when humans still believed the sun orbited around earth instead. Is it not high time we came up with terms that match what is presently known?
