Question

which characteristics can be used to differentiate star systems? select three options.
the number of stars in the system
the level of dust and gas
the age of the stars in the system
the way stars are organized in the system
the color of stars in the system

Explanation:

• The number of stars in a system (e.g., single - star, binary, or multi - star systems) is a key characteristic.
• The level of dust and gas affects star formation and the overall environment of the star system.
• The way stars are organized (e.g., hierarchical or co - orbital arrangements) is also a differentiating factor.
• The age of stars in a system is more relevant for individual star studies rather than differentiating entire star systems.
• The color of stars in a system is mainly related to the properties of individual stars (like temperature) rather than the system as a whole for differentiation purposes.

Answer:

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