Well, they don't, really. It's an illusion born of the fact that the Earth rotates. The north end of the rotational axis points to a spot in space that happens to be reasonably close to the north star (Polaris). Thus, as the Earth turns, the apparent position of Polaris doesn't change very much, while stars further from the spot where the axis points trace apparent circles around that point. Polaris itself traces a very small circle, too.
It is interesting to note that the Earth's axis precesses, like a spinning gyroscope, with a period of about 26,000 years. So, thousands of years from now, Polaris will be far removed from the apparent point of the Earth's axis on the sky, and some other star will appear to be the "north star".
They don't. They move in eclipses with the gravitational source at one foci. And they move that way because gravitational attraction is an inverse square equation dependent on mass and radius.

First of all, The stars don't surround the Earth, the stars surround the whole solar system. The reason why the stars surround the solar system is because our solar system is actually a galaxy and in the center of this galaxy is the sun which is actually a star so really we are just a part of the stars!!!
It is not. The brightest star in the night sky is Sirius. It appears so bright because it is a fairly bright star overall and is pretty close to us in terms of interstellar distance at a distance of 8.6 light years.

Is rigel the Brightest Star?
No, Sirius is the brightest star in the night sky. Rigel is one of the brightest stars in the constellation of Orion.
Which constellation contains some of the brightest stars in the Northern Hemisphere?
After the sun the brightest star is Sirius in the constellation of Canis MajorIn addition to the star Sirius (brightest star in the night sky) in the Canis Major constellation. Another bright star in the night sky is Rigel (7th brightest star in the night sky) and it belongs to the Orion Constellation. The Orion constellation is the hunter. Next to Rigel are two other stars that make up Orion's belt. The other two stars are Bellatrix (27th brightest star in the night sky) and Betelgeuse (9th brightest star in the night sky). The Orion constellation stands out on the Northern Hemisphere between the months of January and March and during the summer months in the Southern Hemisphere.
What are the three brightest stars in the sky?
The three brightest stars in the sky are Sirius, Canopus, and Alpha Centauri. Sirius is also known as the "Dog Star" and is the brightest star in the night sky. Canopus is the second brightest star and Alpha Centauri is the third brightest star.
