Question

The Big Dipper will look different 100,00 years from now than it does today because?

Answer 1

Yes but not much change. every thing out there is moving ,but by man's time it is just seconds.

Answer 2

the constellations you see are actually an optical illusion. The stars are not actually aligned to form the pattern.

The sun is also revolving around the centre of the galaxy which, in time, will alter our perspective on the universe.

Answer 3

...because stars move....a lot. We just don't live long enough to see any appreciable changes.

Answer 4

Because the universe is expanding and we are not at the center of it, the constellations will not appear the same to us after a long time of expansion.

Answer 5

The stars are part of a small cluster and moving in the same direction. It's called the Ursa Major Moving Group. The two stars at the ends, Dubhe and Alkaid, are not part of this cluster and moving in different directions from the others.

Answer 6

The stars making up the constellation will have moved a lot from their current position, as their parallax is large and theses stars have their own motion, which becomes noticeable over a fairly short time in astronomical terms 100,000 years is a short time.

Answer 7

From Earth's vantage point, or from any other for that matter, every star and galaxy in the sky will look different in the far future. The reason for this is because everything in the universe is currently in motion. Over time, positions of all celestial bodies will move and alter their distances to each other. It takes hundreds of thousands of years to notice a significant change though.

BTW . . . The Big Dipper is actually not classified as a constellation because it is simply the seven brightest stars of the constellation Ursa Major, the Great Bear. The stars simply stand out to form a dipper. They just happen to be most noticeable in the Ursa Major constellation.

Answer 8

Because not all stars in the Big Dipper belong to the same cluster. Dubhe and Benetnash (alpha and eta Ursae Majoris) do not move along with the other 5 stars, so the appearance of the asterism is going to change.

Answer 9

because us and each of the stars in the big dipper are all traveling in different directions. from our point of view, you can't tell that they're in a different spot from day to day because we are so far away but after 100,000 years, they will have moved enough that it will be visible
