It’d be cool to see Comets hurling across the Solar systems at high speeds, occasionally obliterating ships caught in their path.
When moving at high speeds they would deal massive, wide, railgun style damage to ships, but if they impact they shatter into pieces, become inert, and slow to a stop.
Would be made of pure solid tritanium (or a mix of high value resources) and if you can slow one down with a tractor beam (or survive “catching” it) then the dense ore would be yours for the taking. (Not an asteroid)
To ease simulation, they could fly in a straight line across the galaxy and just turn around somewhere far out, or they could actually have elliptical orbits so they don’t just hit asteroids (and so players have a chance to catch them at low speed)
