SM targetting

Do SMs target on asteroids or planets if that is what is closest?

I'm working on a perl script to deal with all this for PBeM. I have easy
turning (You give ships speed, current direction, and turn and it does the
rest), each player gets a file every turn with his current directions. I have
objects that the game moves (IE Asteroids), I have auto map sizes. I have yet
to do the parts that make sure 1) you start in the position you ended AND 2)
do a legal move. I also have mines in the works (calculate ships movement,
check for distance of mine to ships movement (point to line for 1 line, point
to lines for 2 point). I currently have SM to closest ship with 6MU. I also
have a printout that is range and arcs to everything other than SMs on the
board. I do not yet verify that SMs are fired at legal ranges from their
ships. When I do however I'm thinking about having the SMs go ballistic and
not target if fired at too great a range.
(Come on, SQR((ShipX - SalvoX)^2 + (ShipY - Salvo&)^2 )

Other parts I am working on are EW. What is the recommendation for ranges? I'm
now thinking ship exists across the map, 80 for a mass (spoofable via EW) 40
for class, 12 for a look at the SSD. You'ld get a circle (of appropriate
color) beyond 80, You'ld get a filled circle of appropriate size and color
beyond 40, and ship pictures once the ship entered 40 MU. Even if range
increased you should always get whatever your best info was.

One potential problem is currently this is all for cinematic. Eventually I'll
move to vector.

Only if the asteroids or planets are enemy ships.
