2 .Locate the ecliptic and name one star on or very near it. Try to find one within 10 degrees north or south.________ is about _____ (state its declination here, it is difficult to estimate the degrees from the ecliptic) N/S of the ecliptic. Indicate in your answer if the star is north or south.
3 .Follow along the ecliptic on the night sky simulation web site. What is the maximum (most northerly) declination the Sun will reach? ____________. What is the minimum (most southerly) declination the Sun will reach? ____________.
If clicking directly with the cursor on the ecliptic at their maximum and minimum declination does not give you the cursor coordinates, try to find a star or other celestial object as near as possible and click on it for the declination.
Maximum declination of the Sun: __23.45 degrees____________
Minimum declination of the Sun: _-23.45 degrees _____________
