Do we see a different part of space everyday?

Question

Well, the earth revolves around the sun and spins by itself too.

So, don't we see a different part of the sky everyday?

But then, how can we see the North Star and other constellations everyday???

I am not in middle school.

Answer 1

Well, if you lived on the equator, you would not see the North Star every day. And if you lived in the southern hemisphere, you would never see the North Star. There's a clue hidden in there.

I suggest a Google search for "circumpolar constellations".

And yeah, on average we see 4 minutes of "new" sky every night (though it's the same old sky you saw on the same night last year).

Answer 2

Yes the earth does spin, and all the stars are straight out from a point on earth to the center. Some stars are straight out from the center, to the north poll. Those stars seem to spin around the north poll so will always stay in the same location that we can see. Other stars that are straight out from the equator will change all the time. Now the stars them selves do move, but it is harder for us to see that. Orion is the best constellation to see now, in a few weeks there will be others that are great.

Answer 3

Slightly. The earth's North Pole is fairly constantly oriented towrds Polaris, and in the northern hermisphere, the entire night sky revolves around Polaris. What changes during the year is the time of day/night relative to that cycle that the constellations come into position. Thus, the winter sky has a particular look, with Orion prominent high in the night sky, while in the summer Orion is "out" in daytime and so is not seen at night.

Answer 4

Boy, if you're in Middle School, you sure DO!

As far as astronomy goes, the small space the earth revolves in compared to the great distances to even the nearest visible star makes it appear that the night sky is essentially unchanged night after night. Think of how the view of the mountains 20 miles away changes so little when you move between windows in your house.

Answer 5

Slightly, which is why the constellations change throughout the seasons. Much of the motion (like the universe expanding) is happening so relatively slowly that there's no real way for us to measure it in a single lifetime.
