Exercise set five
... Using each pair of observations, calculate the length of the sidereal day. (Hint: start by calculating how much earlier, in seconds, the later occultation occurred, then divide that by the number of days between the observations. This gives you how many seconds shorter a sidereal day is than a solar ...
