Polaris, the North Star or pole star, is a very bright super giant that is orbited by four companion stars. While the system is 434 light years (2.549e+15 miles) from Earth, the combination of the very large, bright primary star with the orbiting companions makes Polaris seem very bright in the northern sky, and brightness appears large in the night sky.

What is the diameter in km of the dwarf star?
There are many types of Dwarf stars - all with different diameters. Our Sun is a dwarf star! A typical neutron star has a diameter of about 24km our Sun has a diameter of 1.392×106 km So our Sun is about 58,000 times bigger than a neutron star.
What effect do planets have on the stars they orbit?
The gravity of the star is usually many times larger than the planets due to the overwhelming mass of the star in comparison. The planets do have a gravitational pull of their own though, which has an effect on the star it is orbiting. It will cause the star to move slightly off centre as it pulls on the star during its orbit. The bigger the planet, the bigger the pull. By looking at distance stars, astronomers can see the effects of planets by observing a 'wobble' in the star as the unseen planets orbits it. They can then calculate the size of the planet and distance by the size and speed of the wobble.
When a stars ten times bigger than the sun explode is a?
When a star ten times bigger than the sun explodes, it undergoes a supernova event. This explosive event releases a tremendous amount of energy and can lead to the formation of a neutron star or black hole. Supernovae are among the most energetic events in the universe.

What causes dark holes?
If you mean "Black Holes" then they are formed when a star very many times bigger than the sun goes supernova and collapses in on itself.
