The earth is moving at great speeds around the sun. If you want to go to the sun, you have to brake an equivalent amount. Otherwise you'd just orbit the sun (like the earth does).

So if you want to go to the sun from the earth, first you have to escape the earth, and then you have to counter all its speed.
