Imagine that the Earth’s rotational axis was tilted 90 degreesrather than 23.5 degrees (so the polar axis would point towards theSun twice a year). Describe the apparent motion of the Sun andstars over a 24-h period on the winter solstice from (a) the NorthPole, (b) the equator, and (c) the South Pole. Note that the Sun’sangular diameter is 0.5 degrees.
