La eclíptica se encuentra inclinada respecto al ecuador celeste:The ecliptic is inclined to the celestial equator by an angle (obliquity) of:
Show the answer
Correct answer: a) 23º 27'
Why it is correct
The obliquity of the ecliptic (ε)—the angle between the plane of the ecliptic and the celestial equator caused by Earth’s axial tilt—is approximately 23° 27′ and sets the Sun’s maximum declination at the solstices.
Why the others are not
- b) 27° 23′ swaps the degree and minute figures.
- c) 22° 31′ is less than the true obliquity of the ecliptic.
- d) 37° 22′ is unrelated to the tilt of the ecliptic.
How to work it out in the exam
- Obliquity of the ecliptic to the celestial equator: ε ≈ 23° 27′.
