The correct ranking for the objects from largest to smallest is:
- Galaxy

A galaxy is a large system of stars, gas, and dust held together by gravity. Stars are smaller than galaxies and are made up of hot, glowing gases. Planets are even smaller than stars and are celestial bodies that orbit a star. Filaments are even smaller and are thin, elongated structures found in space.
