One thing which may solve the current "useful information but too much clutter" is an advanced information checkbox
Toggling it on would list every useful bit of information that's been suggested, adding columns as needed, and additionally allow filtering by certain planet conditions like how hot it is, etc.
You'd have the simple and easy to look through view, and then when you're making the final choices on where to settle, enable advanced and see if there's any issues with it.
And I'll throw in a +1 to the planet name search bar suggestion, that'd be quite useful
Might also be nice to allow sorting by tags, but while nice, searching for the names at least would be great
