The Moon`s Orbit
... In this the lab, you will chart the Moon’s orbit and measure its true orbital period. You should find that the period does not exactly equal the period of the Moon’s phases. As discussed in class, the month is defined by the time period for the phases of the Moon, which are due to the relative posit ...

... So, P = 1 / 4.15 = 0.241 years = 88 days (as shown in Table 4-1 on page 70). 36. Mercury takes longer to go from greatest western elongation to greatest eastern elongation than vice versa because the orbital distance is greater, as can be seen in Figure 4-6. This can be verified with the dates, too, ...

... Aside on the Speed of Light: 1. It might seem that Rømer’s determination of the speed of light is circular in our context, since he used the radius of the earth’s orbit to get it, and we want to use it with the observed aberration of starlight to get the radius of the earth’s orbit. 2. BUT, we hav ...

The time of day at which shadows are shortest is the time when the Sun is due north, so the shortest shadow points in a north-south direction. Some children may find it hard to believ ...
