which characteristics can be used to differentiate star systems? select three options. the number of stars…

Brief Explanations:

The number of stars can classify systems as single - star, binary - star etc. The level of dust and gas affects star formation and evolution. The way stars are organized (e.g., in clusters or alone) is a key characteristic. Age and color are more about individual stars rather than differentiating whole star systems as primary factors.

Answer:

• the number of stars in the system
• the level of dust and gas
• the way stars are organized in the system
