Default Useless planetary system

Unfortunately, the 8 planet system only has one planet at a suitable "Earth" distance from its star and that planet is probably a gas giant. The discovery of 8 planets is probably not revolutionary, it's likely many systems exist with the same or more planets, but resolution or motion measurements hasn't allowed for detection.

Maybe the Jupiter-sized planets have moons ....

The news here isn't that other planets have lots of planets. The news
is that this is the first time we've _detected_ so many. Nobody is
surprised at the number.

(And it's pretty silly to classify such a system as "useless".)

Mindnumbingly boring but then again when mediocrity is the aim of observers it doesn't take any effort to arrive at that excuse for an existence.

With the South Pole about to turn midway to the circle of illumination this evokes pride in our planet and its amazing diversity.
