Given exactly 360° in a circle and 365.24 days in a year, how many degrees per day does one's view of the night sky shift? (This assumes one looks in exactly the same direction, at the meridian - the middle of the sky defined by a line across it running due north to due south, at exactly the same time each night.)
If you are at latitude of 40 degrees north of Earth's equator, what is the angular distance from the northern horizon up to the north celestial pole? From the southern horizon to the south celestial pole?
If a star is located exactly __________________ it will not appear to move during several hours of observing the night sky.
A. on the celestial equator
B. at the north celestial pole
C. on your horizon
D. due east
E. at your zenith
