Aborting from Hyperspace:
“Piloting Skill = The appropriate piloting skill level that corresponds to the ship type that is being flown.
NumPlanets = Number of planets, suns, asteroids, moons, and comets in the system that you emerge at.
Rand = Random number between 0 and (300 + 20 * Piloting Skill).
Ship Destroyed = True if 4(NumPlanets) > rand.
- Movement: Aborting
Size of the planetary body has no bearing. It's just *number* of planets (see rules for everything being a 'planet')
So some systems are far more dangerous to abort hyperspace in than others.
Pyria has 15, so you're looking at
Ship Destroyed if rand 0 (300 + 20 * Skill) < 60.
At 0 skill, that's 60/300 = 20% chance of the equivalent of "sunning".
1 skill, 18.75%
2 : 17.6%
3 : 16.66%
AKA: best case you have a 3/4 chance of Not dying if you abort in Pyria.
Iridonia only has 2 "planets", so it's
8/300 = 2.6 % worst case, and 2% best case.
