33. A Planet Must Revolve Around A Sun
It is clear that we also need to revolve around the sun. For the Earth, we rotate around the sun in our daily pattern. This happens every 23 hours, 56 minutes, and 4 seconds. We round up to a 24-hour day, of course.
We also move around 60,000 MPH around the sun too. However, the days on another planet may not operate the same way. This is okay as it won’t hurt human life to have longer or shorter days depending on the needs of the planet we’re on. The planet still needs to revolve around the sun regardless.
