we circle around the sun right so how come we see the same stars at night every night?

Answer 1

We don't exactly see the same stars every night, but I know what you mean.

First of all, the other people are NOT correct in saying the stars change because we circle around the sun. The stars change because the Earth's axis is tilted. In winter we're tilting toward a different direction than in summer, and so the stars look different. If you're in the Northern hemisphere though, you can always see the North star (Polaris) year round.

The stars don't "change" because they are very very far from us compared to the sun. Our movement around the sun is so tiny compared to our distance to other stars. If you were staring at wide open fields and just moved your head by an inch, what you see wouldn't change either.

Answer 2

Well your question itself suggests the answer. It is impossible agree to see same stars every night since earth moves around sun. In fact the night sky will change everyday little bit. However a significant change will happen only once in several days. Actually the space scientists could provide you with exact details including; each night how much new sky and new stars we see and how much previous night's sky and star we lose; also how many days it will take to get a completely new sky and new set of stars etc.

It is mathmatical, there must be well defined ready made night sky maps available.

Now of course when we simply look at the sky the sky looks same each night. you feel there are same stars every night. it is because they look same at that distance agree? however if you carefully observe then you may see different stars in the same location in the sky on different days.

Answer 3

As we look at the night sky, the earth is rotating on its axis. Because the earth is rotating, the stars seem to rotate in the opposite direction. This movement is an optical illusion. As the earth turns, different stars can be seen at different times during the night. Certain groups of stars, or constellations, observed at 8:00 P.M. will appear to have moved when observed a few hours later. Because the earth orbits the sun, different constellations can be seen from different locations on the planet. If the stars were observed each night, they would seem to remain in the same position relative to each other.

I hope this helps.

Answer 4

We don't. It only seems that way, because the stars move very slowly with respect to the Earth in its movement around the Sun. The stars rise 4 minutes earlier with each day, as the Earth's sidereal rotation (with respect to the stars), is 23 hours and 56 minutes.
The syndonic rotation (with respect to the Sun), is 4 minutes longer, because it takes that long for the Earth's rotation to catch up with its revolution track around the Sun.
The same thing applies to the Moon: The Moon's sidereal rotation is 27 1/3 days, but its rotation (with respect to Earth), is 29 1/2 days, because it takes just over 2 days for the Moon's rotation to catch up with its revolution around our planet.
With the stars, however, there is a very subtle change, during the course of the year; after just a couple of weeks, the change becomes noticeable.

Answer 5

But we DON'T see the same stars every night. They are shifted by about 4 minutes every night, because of the distance the Earth moves around the Sun every day. The stars visible in January are totally different from the stars visible in July, except for those close to the celestial pole,

Answer 6

the stars are all much further away than our sun or its planets. Relative to them, we're hardly moving, except in terms of rotating on our axis (which is why we have day and night). So as we spin around on a daily basis, we see the same stars at night, but they also appear to move, like the sun and moon due to our spinning (N star is always N).

Answer 7

We don't. We see different stars in Summer than in winter because we move half way around the Sun in 6 months.

Answer 8

you have to understand that the earth rotates on its OWN axis which makes ONE DAY when that rotation is complete and at the same time rotates around the SUN and when that is complete that is ONE YEAR..it takes awhile for us to notice the change you will see the same star, it seems every night but in reality it IS moving very slowly (well the earth rotating)...hope it made sense

Answer 9

They're not the same. They only seem the same because there are so many stars to be seen.

Answer 10

If you will go to this web site every month
www.skymaps.com

You can download a free star chart -------- after about 2 months you will actually be able to see how the sky changes-------- on paper.
