Give the name of the path that the Sun follows on the celestial sphere during the year. Assuming the Earth’s orbit around the Sun is circular, state the values of the Sun’s right ascension and declination at: (i) The summer solstice (ii) The winter solstice (iii) The vernal equinox (iv) The autumnal equinox An observer points a telescope at the zenith at 19:00 during the night and observes a star whose right ascension and declination values are α = 01h15m20s and δ = 700 , respectively. The observer returns to the telescope at 22:30, and observes another star at the zenith. What are the right ascension and declination values of the second star, assuming that the telescope has not moved between the two observations.

Question
Give the name of the path that the Sun follows on the celestial sphere during the year. Assuming
the Earth’s orbit around the Sun is circular, state the values of the Sun’s right ascension and
declination at:
(i) The summer solstice
(ii) The winter solstice
(iii) The vernal equinox
(iv) The autumnal equinox
An observer points a telescope at the zenith at 19:00 during the night and observes a star
whose right ascension and declination values are α = 01h15m20s and δ = 700
, respectively. The
observer returns to the telescope at 22:30, and observes another star at the zenith. What are
the right ascension and declination values of the second star, assuming that the telescope has
not moved between the two observations.
