That's not saying much, considering how a short time that would be on most ship designs (between shutting thrusters down and speed turning negative).and didn't encounter a single asteroid until I was dragged back at Nauvis
When you're actually stationary (in orbit), the direction of asteroid's speed vector is probably just random, considering how they often miss the platform.and asteroids spped is proporional of speed of a platform plus small constant, so that already spawned asteroids slowly dragged to a stationary platform
However, the magnitude of their speed seems to be either constant, or in a very narrow window.
