Certain authors caution against identifying "day" with rotation period. For example: Seligman, Courtney. "Rotation Period and Day Length". Archived from the original on 2018-09-29. Retrieved 2011-06-03. A Cautionary Note: Because the rotation period of the Earth is almost the same as the length of its day, we sometimes get a bit sloppy in discussing the rotation of the sky, and say that the stars rotate around us once each day. In a similar way, it is not unusual for careless people to mix up the rotation period of a planet with the length of its day, or vice versa.
