[Star Wars] How does hyperspace work?

Why is it that you can punch the coordinates of your destination and get there safely from anywhere (at anywhere around a certain planet)  Shouldn't you have to make your way to a very specific point so as not to collide with objects?

You can't just punch in coordinates and go from anywhere. Hyperspace is a separate dimension from realspace that the ship travels through in order to hop over wrinkles in the fabric of realspace. Large objects like stars create mass shadows in hyperspace that you have to navigate around. Since you have to avoid those areas, there are well known hyperspace routes that most people use to get around without having to make new complex route calculations. 

This also explains Han Solo's impressive Kessel Run. He was able to make the trip in 12 parsecs. At first glance that statement seems stupid, because a parsec is a unit of disrance, not time. Solo was able to make it in 12 parsecs because he was able to calculate a shorter hyperspace route than the one smugglers normally used, resulting in a much faster trip.
