They are also moving at those same speeds. This is why it’s actually very hard to de orbit into the sun. If you launched from earth and pointed your spaceship directly at the sun you’d miss it. You would first need to aim practically opposite the direction of Earth’s orbit and firing your engines would actually be slowing you down.

Related to this is they are stuck in the planets gravity well. While logically your brain tells you that if you could move the Sun all the other planets would get left behind, what would happen is all the planets would come with the sun as it is moved.
