How many stars are in the Big Dipper?

There are seven stars in the Big Dipper: Dubhe, Merak, Phad, Megrez, Alioth, Mizar, and Alkaid.

Dubhe and Merak, the stars on the outer side of the Big Dipper's basin, are sometimes called The Pointers because they point toward Polaris, also known as the North Star. On their own, the seven stars of the Big Dipper form an asterism (a relatively small pattern of stars), not a constellation. However, they're also part of Ursa Major, a true constellation, forming the bear's hips and tail.

What is the part of a constellation called that is easily recognizable like the big dipper?

A pattern of stars which is not an official constellation (although often they are part of constellations) is called an asterism. The Big Dipper is an asterism; it is actually part of the constellation Ursa Major, "The Large Bear". Another asterism is the Summer Triangle, three bright stars which are actually part of three different constellations.

Does the big dippers stars move?

Yes they do. But they're so far away that you can't see the effects of their motion over the duration of a human lifetime.

What is the technical name for the big dipper?

The technical name for the big dipper is Ursa Major, literally, "The Great Bear."

How big is a star?

They're different sizes.

Simplistic. Supergiants, Giants, Dwarfs, Sub dwarfs, White dwarfs.

Supergiants are huge. Some of them are large enough that, if they replaced the sun in our solar system, Jupiter would be the innermost planet; the orbits of all the inner planets would be inside the star. The largest known is VY Canis Majoris which is about 2,100 times larger than our Sun [See Link] which would mean 9,261,000,000 Suns would fit inside.

White dwarfs, on the other hand, are only about the size of the Earth (though they're very dense; in many cases they have about the same mass as the sun).

Neutron stars are quite small: a few miles in radius. They're incredibly dense, since they manage to pack a mass up to around 2 times the mass of the sun in that tiny space.

See link for pictorial representation of various star sizes.

-------------------------

Our Sun is a Star. Sun is much much bigger than Earth. All stars are like Suns in the sky. Most Stars are much much bigger than our Sun.

The Sun's diameter is 864,938 miles (1,391,980 km). This is almost 10 times larger than the planet Jupiter and about 109 times as big as the Earth. The volume of the Sun is 1,299,400 times bigger than the volume of the Earth; about 1,300,000 Earths could fit inside the Sun

In fact, if you think of the Sun as a basketball, the Earth would only be the size of the head of a pin

What are the stars in the big dipper?

Starting from the handle, the main stars in the big dipper are Alkaid, Mizar and Alcar (an optical double star), Alioth, Megrez, then down to Phecda, across the bottom to Merak, and finally up to Dubhe on the lip. If you extend a line from Merak up through Dubhe about five times the distance, you should find Polaris, the North Star.

How can the big dipper be used ito find direction in the northern hemisphere?

its drzymla isn't it lol!! If you live in the Northern Hemisphere, you can use the Big Dipper to easily locate many other stars and constellations. If you follow the handle of the Big Dipper and 'Arc to (a very bright star) Arcturus', you will find the kite shaped constellation Bootes. Continue on that arc path and you will see another bright star, Spica, in the constellation Virgo. If you follow the two bottom stars in the cup of the dipper in a downward direction, you will find Regulus, which is the brightest star in the constellation Leo.

Which constellation can help traveler find north pole without a compass?

Ursa Major, the great bear. Part of this constellation has a very prominent asterism

which people refer to as the "Plough" or the "Big Dipper", part of this asterism is what

is used to point to the pole star.

=============================================

So it's actually the pole star, in the asterism of the "Little Dipper", in the constellation

of Ursa Minor, that can help traveler find north pole without compass.

As a ship sails a steady course the North Star sinks in the sky In what direction must the ship be sailing?

It is moving South. At sea you could measure the angle between the horizon and Polaris with a sextant. This angle is approximately equal to your Northern latitude. There are some mathematical corrections one can perform to get a more precise answer, but the further south you sail, the lower Polaris will become. Eventually, you will not be able to see it anymore. Polaris is not visible from the Southern Hemisphere and there is no South Star. The ship is in the Northern Hemisphere, moving South.
