Lab #3: Planetarium PART #3: RIGHT ASCENSION & DECLINATION 1. What group of constellations lies along the ecliptic? 2. Besides the constellations, what other celestial objects are found on (or near) the ecliptic (name 3)? 3. How does the celestial equator differ from the ecliptic? 4. How is the celestial equator similar to the ecliptic? 5. Is the right ascension coordinate found on the ecliptic or the celestial equator? 6. With respect to the celestial equator and the ecliptic, where is 0 hours of RA found?Explanation / Answer
1. What group of constellations lies along the ecliptic?
Answer:
· Pisces.
· Aries.
· Taurus.
· Gemini.
· Cancer.
· Leo.
· Virgo.
· Libra.
2. Besides the constellations, what other celestial objects are found on (or near) the ecliptic (name 3)?
Answer: Sun, Planets (Earth, etc.) and Moon.
3. How does the celestial equator differ from the ecliptic?
Answer: The ecliptic is the circular path on the celestial sphere that the Sun appears to follow over the course of a year; it is the basis of the ecliptic coordinate system.
But, the celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth. This plane of reference bases the equatorial coordinate system.
4. How is the celestial equator similar to the ecliptic?
Answer: Both are the circular path of the celestial sphere.
5. Is the right ascension coordinate found on the ecliptic or the celestial equator?
Answer: The right ascension coordinate found on the celestial equator.
6. With respect to the celestial equator and the ecliptic, where is 0 hours of RA found?
Answer: The R.A. scale's zero point is defined to be at the First Point of Aries, one of two points where the ecliptic and celestial equator cross.
Thanks!!!
