Once the Universal Gravity Scanner (UGS) has been researched, you can use it to scan the entire universe and
create a list of all planets with total land within the land range you specify.
The UGS requires 1 hours to reset before you can use it again.
If you want non-attackable planets (newbie, disabled, vacation, etc.) included in your scan, you must check the box
called "Include non attackable planets".
