Graybeard's post has the Truth.
Hell, even a Christian has told me that information, especially part of why sometimes our summers are hotter and winters are colder is because the Earth does not PERFECTLY revolve around the sun. It strays sometimes, and sometimes the gravity from the sun is stronger. If you really look at the Earth's tracks when rotating, it is more of a curvy line than a perfect straight line.
Shows you many Christians are still in the "the Earth is flat and the Sun revolves around the Earth" mentality.
