The basic asteroids shouldn't be affected by the gravity of the black hole. Instead, they have a certain unchanging velocity as they move across the screen.
To add variety, they could come in multiple sizes and have a slight spin to them.
They should spawn off screen and should always have a negative x component to their velocity. i.e. they can't approach the rocket from the rear and chase it.
When the asteroid leaves the screen, it should be destroyed.
