Question

D) The pole star and constilation are discovered by whom?​

Answer 1

Answer:

These constellations were first catalogued by the Greek astronomer Claudius Ptolemy in the 2nd century CE. Ptolemy did not name these constellations, but simply documented them in his Almagest. The constellations were well known to observers long before his time

Answer 2

Answer:

Pytheas

During the 1st millennium BC, Beta Ursae Minoris ("Kochab") was the bright star closest to the celestial pole, but it was never close enough to be taken as marking the pole, and the Greek navigator Pytheas in ca. 320 BC described the celestial pole as devoid of stars.
