The Astronomy Center has provided educational resources to introductory astronomy educators since 2003. Over the past 20 years, the rapid pace of discovery has rendered some of our linked resources obsolete. Thus, the Astronomy Center will be decommissioned on March 1, 2022. Our highest quality resources will be retained on ComPADRE.org.
This simulation shows the difference between the sidereal and solar day by showing the orbit and rotation of a planet (blue) around sun (orange). It uses an orange arrow to represent where Sun would be seen in the sky relative to the background stars. Users can toggle between the geocentric and heliocentric point of view. The parameters are initially set to model a general direct rotation scenario. The user can also select a planet with a retrograde rotation, and the Earth-Sun system can also be shown which simulates the exact the orbit and rotation rates of Earth.
