Orbital Space Defense Mine

For years, many planets have modified various space mines and satellites for
use as a planetary defense weapon. Most are either remote controlled and/or
have a droid brain programmed to passively scan during "quiet" times for any
specific targets that the owners may have placed in its memory. During an
attack the mines switch from passive modes to active mode and begin scanning
actively for any hostile craft (this is usually done by a signal sent from
the planet, often including details needed for identifying a likely target).
Once the mine acquires a target, it powers up its solid-fuel boosters and
rockets toward it (note that once the boosters are ignited, they cannot be
turned off and they will only burn for 5 rounds until all the solid-fuel is
burnt off). Once the mine reaches a distance of at least 15 space units from
the target (depending on whether or not there is still solid-fuel to carry
it any closer or not), the mine detonates its powerful fusion warhead.
