Actually, the stars are moving, as is everything else in the universe. It's just that the distances are so vast from our perspective (viewing point) that any movement is virtually undetectable.
I don't think so. A constellation is defined as the region between certain coordinates in the sky (declination and right ascension - equivalent to latitude and longitude on Earth). These coordinates move, in the sense that the entire reference system moves compared to the background stars, due to the precession of Earth's axis. However, I read that the coordinates for the year 1875 are used; it seems they have not been adjusted.
All of the stars move; every one has its own "proper motion". However, the proper motion of even the fastest and closest star isn't enough to be noticeable over several human lifetimes.
Perhaps you are referring to a star that does not APPEAR TO move? One star, Polaris, is so nearly directly above the north pole of the Earth that it seems to stay in one spot in the sky, while all the other stars appear to wheel around it. But if you point your camera at Polaris and take a long time-exposure, you will see that even Polaris "moves"; it isn't EXACTLY above the north pole, and appears to make very tiny circles in the night sky.
In fact, Polaris is about 0.6 degrees away from being exactly above the north pole.
Most of the stars in the night sky that can be seen with the naked eye are in fact not moving very much relative to us and to other stars in the Milky Way. The stars we see are within the Milky Way itself. The galaxy is turning relative to other galaxies, but we are turning along with the other objects in the galaxy. There may be a small amount of movement of those visible stars but it is not enough to be noticeable to us earth-bound observers.
The movement that you hear and learn about, the movement of galaxies away from us at great speeds, involve galaxies and not individual observable stars. And there are very few galaxies that are at all visible from earth.
You may be using the term 'star' the way it was used in ancient times, thinking of planets as moving stars, and the distant stars as 'fixed'.
______________________________
While all of the stars - and the Sun itself, for that matter - are moving fairly rapidly through the galaxy, you would need to live a dozen lifetimes or more to actually notice any movement. The stars are too far away! When we talk about "apparent movement", we are generally talking about the rotation of the Earth. With us standing on the Earth like a child riding a carousel, we see the stars all moving along together - when it is US doing the moving.
From that perspective, the only "unmoving star" is the north pole star, Polaris. It appears to be fixed in the sky, because of the useful - but ENTIRELY coincidental! - alignment of the Earth's axis of rotation and the star.
Because Earth is travelling through space at great speeds.
because its almost directly in-line with the north pole
it is situated in the direction of earth's axis
They don't. It is Earth that rotates; as a result, stars (and groups of stars) seem to change direction in the sky.
They don't. Earth does.
there are 88 constellations. you can see them all in a year on the equator. most of them are from Greek mythology. Whenever a new star is discovered, it is added to the constellation it is nearest to.
The sky is divided into 88 separate constellations. However, new constellations have not been made up for hundreds of years, and when new stars are discovered they are simply thought of as being included with whichever constellation they are closest to.
No. The Zodiac are 12 constellations that lie in the plane of the ecliptic; circumpolar ("moving around the pole") stars are well above or below the ecliptic.
The constellations are different due to the fact that you're looking completely different parts of the sky. However, some constellations which are directly above the Earth's equatorial regions remain the same.
If you were on the Equator you would see all of them. Otherwise it depends where you live. I live in New Zealand at latitude 35° S. So I can't see any northern stars closer than 35° to the North Celestial Pole. If you live in the north at say 35°N, then you wouldn't see those stars which are closer than 35° to the South Celestial Pole.
Stars and constellations appear to move in the night sky because the Earth is rotating, while the stars and constellations stay there.
Stars move.
All stars (and constellations) move from east to west, due to Earth's rotation (which is from west to east).All stars (and constellations) move from east to west, due to Earth's rotation (which is from west to east).All stars (and constellations) move from east to west, due to Earth's rotation (which is from west to east).All stars (and constellations) move from east to west, due to Earth's rotation (which is from west to east).
All of the stars in the Milky Way Galaxy are moving... however, we, in our lifetime, will never notice the constellations changing.
Constellations are patterns of stars, so stars cannot be constellations.
Constellations are not stars. Groups of stars that look like they form various objects or shapes are called constellations.
Patterns of stars are called constellations.
The sun doesn't actually move the earth moves so does the constellations and the stars. We see them move because the solar system spins on an axis just like earth but the earth moves much faster. So we see things move but at a very slow pace all day. The constellations and stars in the sky seem to move because just like all planets they move with the solar system.
Because the stars do not move, but on the other hand, the Earth does. Therefore, sometimes you will not see the same constellations in the same place every night.
yes constellations are made up of stars!!!!!
No, constellations are imaginary patterns of stars.
No - they are made up of stars. As long as the stars are there, the constellations will be there too.
