same stars in the sky every day?

Question

hello

i was wondering why do we see same stars in the sky every night
i live in europe! for example, do people in australia see other stars?
cuz i live north and they south, ?
and why are same stars in sky at winter and in summer time ?
im looking forward for some answers

Answer 1

As you sail south, Polaris will get lower and lower on the north horizon until at the equator, it will be on the horizon.

Celestial navigation uses this to determine latitude. O degrees latitude is when Polaris is on the horizon, 90 degrees north latitude is when Polaris is directly overhead, and you would be standing on the north pole.

If you sail south of the equator, Polaris will be below the horizon, so to determine southern latitude you will have to use the Southern Cross as your nightime celestial reference .

Answer 2

The stars are not in the same position every day. They appear to be in the same position from one day to the next, but over the course of a year, the stars (the constellations) rotate across the sky (and this is caused precisely because the earth rotates around the sun). As for using the stars for navigation, all the constellations rotate around a single point approximately over the north pole, and some constellations (like the Big Dipper, Ursa Major) have stars that are lined up in the direction of this point of rotation, and in fact there is a star at approximately that point ... we call it the North Star. The constellations help navigators find North, and their stability from night to night, and the fact that their precise positions can be charted and predicted based on the time of year, also helps locate East and West at night. In the southern hemisphere there are other constellations (like the southern cross) used for this purpose.

Answer 3

Yes, people in the southern hemisphere see different stars that those we see in the north. Here the best known constellation is the big dipper, in the southern hemisphere it is the southern cross. We see the same stars all the time because the way the Earth sits on its axis, however they are in slightly diffent positions throughout the year due to seasonal tilting of the earth towards/away from the sun

Answer 4

Actually, the night sky differs substantially season to season. For example, you only see the Orion constellation high in the sky during the winter. Sirius is known as the dog star because it appears during the dog days of summer. The sky differs from hemisphere, as well.

Answer 5

Right now the constellation Orion is overhead me out my window in central US 6 months from now it will probably over you. I may still be able to see it but it will be much smaller and in a different position because of the earth's rotation.
Yes, we all see the same stars just not at the same time.

Answer 6

You're not seeing the same stars in winter and summer btw as the earth rotates you do see different ones, and people in austrailia will see different ones then you just because of the position of the earth.

Answer 7

yes Australia sees different stars cuz they only appear in the Southern Hemisphere. Stars are seasonal because the earth orbits the sun and is in different postions of the solar system.

Answer 8

Hi. The stars you see every night are called "circumpolar" because they do not set. In the southern hemisphere there are stars visible which are not visible from the northern hemisphere. Some, like the stars in the constellation Orion, are visible from both. (Orion is upside down from Australia!)

Answer 9

Stars stay in place, the earth rotates, depending on what country is facing that constellation at that moment, that is what they see. On earth, the masses of land are fixed in place. So to the stars in the sky are fixed in place.

Answer 10

Imagine you're standing one side of a ball and looking up at what's around you. You see this and that. As the ball your standing on you slowly spins, your view changes and you see other things and things you saw disappear below the horizon. (The edges of the ball that block your view)

Now imagine you're standing on the otherside of the ball and it's spinning just like it was before. Everything that you saw on the otherside of the ball is blocked and you can't see it, because you can't see through the ball.

But there is some overlap, and some things you can see from both sides.

Well, you really are standing on a ball that's spinning.
