What is the approximate angle known as the obliquity of the ecliptic?
Answer
About $23.5^ extdegree$
The obliquity of the ecliptic refers to the angle between the ecliptic plane and the celestial equator. This angle is currently measured at approximately 23.5 degrees, resulting from the tilt of Earth's spin axis relative to its orbital plane.
