If, in the remote future, we establish a base on Mercury, keeping track of time will be a challenge. Discuss how to define a year on Mercury, and the two ways to define a day. Can you come up with ways that humans raised on Earth might deal with time cycles on Mercury?

The orbit of the Moon around the Earth takes 29.5 days. The orbit of the Earth around the Sun takes 365.26 days. Propose one reason why the orbit of the Moon around the Earth is shorter than the orbit of the Earth around the Sun.
