It was told that Romulus was devastated into pieces by the nearby star that went supernova. 

But what happened to Remus (and the Remans for that matter) or any other minor planets in that system?

From the Star Trek: Countdown comic series, Nero and his crew were mining in the Hobus system at the time the star went supernova.


Question: Choosing variables for Discriminant Analysis
Answer: You can get rid of some by looking for pairs that are very highly correlated and randomly deleting one of the pair.

Then you can look at partial least squares, and pick variables that are important in the PLS solution. 

I did this with a similar problem and it worked pretty well (that is, the resulting discriminant function did pretty well)
