Question

Some constellations, such as Ursa Minor, are visible in the sky year-round; other constellations appear for only part of the year. Explain why this happens.

Answer 1

I know this isn't math but no body would help me in the science section.

Answer 2

Night time will always be on the side of Earth facing away from the Sun. Since we orbit in a circle (ellipse), night time on Earth will always be facing outwards towards the stars rather than inward toward the Sun. This is why as we make a full 360 degree orbit over the course of 1 year our view of the stars in the night sky changes.

Answer 3

Ok, thank you then why can we always see Ursa Minor, (aka little dipper).

Answer 4

It is all to do with the latitude that you live on.

Answer 5

Ok, thank you!
