There are two ecliptic poles:
The North Ecliptic Pole is in Draco.
The South Ecliptic Pole is in Dorado
The ecliptic poles are (as of epoch 1 January 2000) at:
- (North) right ascension 18h 0m 0.0s (exact), declination +66° 33′ 38.55″
- (South) right ascension 6h 0m 0.0s (exact), declination −66° 33′ 38.55″
It is not possible to have the ecliptic poles at the zenith in a dark sky. By definition, the ecliptic poles are located 90 degrees from the Sun's position. Therefore, whenever either ecliptic pole is at the zenith, the Sun must be on the horizon. Ecliptic poles can be in zenith at Arctic and Antarctic Circle.
