What is Solethium? Solethium is a game focused on buying and collecting Solethium tokens (Solar system planets, their satellites and space stations) All planets and the Sun are PARENT objects. When you own PARENT object, you will get a certain percentage from every sale of objects directly orbiting that PARENT object. There are certain Solethium Objects with SPECIAL properties. Those are objects like Trade or Research Space Stations, or like satellites with bases on them. They can bring you even bigger profits!
