At 40° SOUTH latitude, you can't see any of the Big Dipper.
At 40° NORTH latitude, the only part of the Big Dipper that ever sets, just barely,
is the last star at the tip of the handle. For that star to be 'circumpolar' as well as
the rest of the Big Dipper, you'd have to travel about 30 miles more north than 40°N.
The Big Dipper is a circumpolar constellation in the Northern Hemisphere, so it is visible year-round but may not be seen during daylight or in regions with constant twilight, such as near the poles during summer.
No, they are all stars. Planets do not "make" any constellations but they may be present around a constellation's stars. Also, the big dipper is not a constellation. It's an asterism. It's part of the constellation Ursa Major.
Subtract your latitude from 90° and that will give the the decollation of circumpolar stars. In northern New Zealand, my latitude is 35°. If I subtract that from 90°, I get 55°. So stars with Declination great than 55° are circumpolar for me.
Circumpolar constellations are those that, from the viewer's latitude, never set. Any constellation found in the zodiac is not circumpolar. These are seasonal. Pisces appears in the Spring in the Southern hemisphere and in Autumn in the Northern hemisphere.
Yes, there are several constellations visible in both hemispheres, known as circumpolar constellations. Examples include Ursa Major (Big Dipper) and Orion. These constellations can be seen year-round from various locations on Earth.
No, the Little Dipper is not visible from New Zealand because it is circumpolar and only visible in the northern hemisphere. However, New Zealand does have its own distinctive star patterns visible in the night sky, such as the Southern Cross.
The Big Dipper is a circumpolar constellation in the Northern Hemisphere, so it is visible year-round but may not be seen during daylight or in regions with constant twilight, such as near the poles during summer.
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.
Standing on the equator, you would not see any circumpolar stars. Circumpolar stars are those that never dip below the horizon, and they can only be seen from latitudes above a certain threshold, typically around 25 degrees (North or South) or higher. The closer you are to the poles, the more circumpolar stars you can see.

No, it's the other way round - the Little Dipper is part of a constellation, the constellation of Ursa Minor.
Circumpolar, like beauty, is in the eye of the beholder. Technically, a circumpolar constellation is one that never sets, but just goes around the elevated pole. That's the north star Polaris in the northern hemisphere, or the blank spot of space above the south pole. This, however, depends on your latitude; the higher your latitude, the more constellations are "circumpolar" for you. I live near Sacramento, CA, USA, at latitude about 38 degrees north, so any constellation within 38 degrees of Polaris is "circumpolar" for me. That includes constellations such as Ursa Major, Cassiopeia, and Draco, but not constellations like Orion.
Circumpolar constellations are those that never set below the horizon. The further north (or south) one travels, the more constellations are circumpolar. Where I live, above the 45th parallel, most of the Big Dipper stars are circumpolar, but Arcturus is not, and the constellation of Orion sets below the horizon in the summer. Equatorial constellations are those that pass directly overhead when one is between the tropics of Cancer and Capricorn. I believe these are primarily the 13 constellations of the zodiac.
Subtract your latitude from 90° and that will give the the decollation of circumpolar stars. In northern New Zealand, my latitude is 35°. If I subtract that from 90°, I get 55°. So stars with Declination great than 55° are circumpolar for me.

Nothing seen in the sky from a point on the Equator is "circumpolar", meaning that everything in the sky appears to rise and set.
A circumpolar constellation is one that never sets from your latitude. The north star, which is named Polaris, is always as high in the sky as your latitude on the earth. If you live in the New York area as I do, which is 41 degrees of latitude, the north star is always about 41 degrees up in the sky. The night sky appears like the inner surface of a gradually spinning top, slowly rotating around its invisible poles, the north star and a point in the far southern sky over the south pole. Any constellation that lies between the north star and the horizon will never set from your latitude. It constantly wheels around the north star, staying the same distance from it. The Big Dipper, Little Dipper, Cassiopeia, and Draco the Dragon are among the circumpolar constellations from here. The farther south you go, the lower the north star sinks in the sky, and therefore the less room between the pole star and the horizon. That means fewer circumpolar constellations in, say, Texas. From the latitude of Houston, 29 degrees, the Big Dipper, Cassiopeia and Draco all set at some times of the year, although the Little Dipper can always be seen. Tonight, (September 7) for instance, the Big Dipper sets just after midnight in south Texas. If you go further north, the pole star gets higher in the sky. There's more room between the north star and the horizon, so more of the constellations are circumpolar. From northern Norway, 70 degrees latitude, stars like Vega, Deneb and Capella never set. From New York, I could not see Capella this early September evening because it's below the horizon, but in Norway they can. One of the constellations that is circumpolar from northern Norway is Gemini, a constellation in the zodiac. The sun traces out a path through the zodiac over the course of a year, and in June and July the sun is in Gemini. This means that in June and July, the sun becomes temporarily a circumpolar star. It seems to move far enough north that it comes between the pole star and the horizon and does not set during those months. June and July are the time of midnight sun in Norway and the polar regions, where the late spring and early summer days are 24 hours long
