Question

At 8pm the constellation gemini is found just over the mountains in the eastern sky. where will it be about four hours later?

Answer 1

Step-by-step explanation:

Every 24 hours the constellation appears to make a complete revolution around our planet ( it is ACTUALLY the rotation of the earth) ...constellations appear to move from east to south to west across the night sky.

360 degrees in 24 hours is fifteen degrees per hour ...in 4 hours it will move sixty degrees to be 90 (east) + sixty = one hundred fifty degrees on the compass or S S E
