Set the chart mode to star atlas. Set the field to 45°. Set the display to center on the Sun and lock on the Sun. Be sure the Sun, the constellations, the constellation outlines, and the constellation names are turned on. Set the date to January 1 and the step size to 1 day. Turn on the animation and record all the constellations through which the Sun passes in a year. Compare your list to the signs of the zodiac. Suppose you were born on December 8. What constellation would the Sun have been in on the date of your birth? What do you suppose your zodiacal sign would be?
