We need to make a decision about sensors

And it needs to be: if you can click on the star, you can see the planets and their class.    OOORRRR: if you've discovered all the planets orbiting the star, they get their class listed when you hover over them (in the star properties view)?  That would still be very handy.

It's no big really but I notice we keep going back and forth about what you can see when you're in sensor range of a star.  Is it a problem to be able to see the planets around a star without having to go and look at each one?  I honestly don't know what considerations are driving this ambivalence.
