What is the length of the big dipper?
The Big Dipper doesn't rotate. The Earth, however, does rotate. The period of rotation is called a day and the Big Dipper will appear to make a full circle every 24 hours.
What day they discovered little dipper?
The Little dipper has been visible in the sky since ancient times it was never "discovered".
How does the big dipper change over the four seaons?
The Big Dipper not only circles the North Star every night and day, it also circles it more slowly every year. Think of it this way: If you looked at the big Dipper and could watch it for a 24 hour period, you would see it go from it's current place in the sky, all the way around until it was back in the place it was when you started watching it 24 hours earlier. However, in early evening winter, the Big Dipper is to the East of Polaris. In summer the Big Dipper is west of Polaris during the early evening hours. Just like the constellations - they rise and set because Earth rotates on it's axis, BUT because Earth ALSO goes around the sun, the stars seem to switch positions from winter to summer.
How many degrees above the horizon is the big dipper?
It depends on the time of night and day - it circles the North Star constantly. The North Star is 34 degrees above the horizon - it stays in the same spot all the time (just about).
What is the altitude and the azimuth of the two pointer stars in the big dipper?
If you spend any time outside at night looking at the stars, you may have noticed that they're constantly moving. The Big Dipper turns completely around the Pole Star every day, almost like the hand of a huge clock. So, if you pick any star at all in the sky, except for the Pole Star itself, the altitude and azimuth of any star you pick are constantly changing.

What is the big dipper's length of rotation?
The Big Dipper doesn't rotate. The Earth, however, does rotate. The period of rotation is called a day and the Big Dipper will appear to make a full circle every 24 hours.
Can you see the big dipper better in night or day?
you can see it better at night a about 12:00
How can you see the big dipper upside down?
if you do it at a different time and turn the planisphere, then look at the Big Dipper and it might be upside down. I know it cuz im learnin bout it, RIGHT NOW! lol
How was big dipper made?
The big dipper is shaped like a pan, which in the past was called a dipper. Dippers were used to scoop up water. It gets the big part from being bigger than the little dipper, another constellation.

How do you go about getting a 3-D picture of the big dipper?
You need to know not only the relative positions of the Big Dipper stars on the sky, but also their distances. The positions of the stars are given in coordinates called right ascension (RA) and declination (Dec). The RAs are usually given in units of hours, which relate to how the sky appears to rotate once a day in (approximately) 24 hours. The Decs tell how far the stars are north of the projection of the Earth's equator on the sky. These positions are fairly easy to measure, by just noting where the stars seems to be in the sky as we see them. The distances to the stars are much harder to measure. The Big Dipper stars are close enough to the Earth so that they seem to move around in the sky a little bit when they are viewed at different times of the year from the Earth as it moves in its orbit around the Sun. This small change in position during the year is called parallax by astronomers. The farther from the Sun, the less the stars move around. The best parallaxes come from a space satellite mission called HIPPARCOS. The HIPPARCOS results show that the Big Dipper stars are between about 80 and 120 light years from the Earth, with errors of a light year or two. With the direction and distance to each star in the Big Dipper, one can then make a 3-D plot of the stars' positions. The stars at either "end" of the Dipper (at the end of the "handle" and the outside "lip" of the bowl) are the farthest away from us. The other fice stars in the middle turn out to be at almost the same distance (80 light years) from us. So, one should envision the ends of the Dipper being the farthest away from us, while the stars in the middle form a nearly flat pattern as viewed from the Earth. Answered by David B. Shaffer, Ph.D. in astronomy, from Caltech.
How does the little dipper change throughout the year?
Each of the stars in the Little Dipper is moving, but they are all moving in different directions. The same thing could be said about any constellation; all the stars have their own "proper motion". But they move so slowly that it takes centuries for the constellations to change much.
When you fall asleep and dream does your eyes move?
Yes. Acually, your eyes move twice as much at night then you move your eyes in the day.
Why does your big toe hurt almost all day but you can still move it?
maybe your shoes are too small!
