Step1: Recall Definitions

• Universe: All space, matter, energy, and time. Largest scale.
• Galaxy: Massive system of stars, gas, dust, held by gravity. Contains billions of stars. Smaller than Universe.
• Solar System: System with a star (Sun) and objects orbiting it (planets, moons, etc.). Smaller than Galaxy.
• Star: Massive celestial body (like Sun) that generates energy. Larger than planets.
• Planet: Celestial body orbiting a star, not a star itself. Smallest here.

Step2: Order by Size

From largest to smallest: Universe (contains all galaxies), Galaxy (contains many solar systems), Solar System (contains a star and planets), Star (larger than planets), Planet (smallest).

Answer:
