Question

Zoom out and drag the sky map until you can see a full circle sky on your screen. Make a mental note of the location of one or two constellations that are near ursa minor. Click on the grey time box that is on the bottom right side of the sky map. Use the slider to fast-forward through time. Go from 22:00 to 6:00. Describe how the location of ursa minor and the other constellations in the sky changed relative to polaris throughout the night and early morning.

Answer 1

Due to the earth spinning on its axis, the place of the constellation seems to be changed during the night and early morning.

What do you mean by Polaris?

Polaris may be defined as the group of stars that make up the Little Dipper. It is very distant from the earth and located in a position very near Earth's north celestial pole.

Polaris does not move, but the constellation and Ursa minor are constantly moving. This movement is not detected by bare eyes. These stars are so far away that we can not see them moving due to the parallax effect.

Therefore, due to the earth spinning on its axis, the place of the constellation seems to be changed during the night and early morning.

And Happy Holdidays too you!
