A solar system is smaller. There are billions of solar systems in a single galaxy.
Each star is a solar system. (some have planets, some don't)
When you look at the sky at night, every star is a solar system and all of them are part of the Milky Way galaxy.
A galaxy cluster is a group of galaxies.

Any planet you fancy. There is no "starting" point in our Galaxy.
Moon (Although some moons are larger than planets), Planet, (Although some planets are larger than Stars) Star, Solar System, Supernova, Cluster, Super Cluster. Universe.
The universe can be organized in various scales: Planetary system (e.g. our solar system) Galaxy (e.g. Milky Way) Galaxy cluster (group of galaxies) Supercluster (groups of galaxy clusters) Observable universe (everything we can potentially observe)
The smallest planet is mercury, and the planet farthest from the sun is Neptune.

Mars is not a galaxy! It is a planet in our solar system.

The smallest planet in our solar system is mercury. It's the smallest known planet in our galaxy, since we would not be able to see one that small in any other far off systems. smaller planets could exist, would they still have to fulfil the same criteria? Ceres, a dwarf planet is only 900km in diameter. This is about the limit, much smaller than this and the planet would struggle to hold a spherical shape.

Mars is the 4th planet from the sun in our solar system which is in the Milk Way galaxy which is part of the galaxy cluster known as the Local Group.
biggest to smallest : universe, galaxy, star/solar system, planet, moon. The Universe is everything that exists and a galaxy is a cluster of billions of stars and then planets rotate around stars and moons rotate around planets.
The range is the difference between the largest and smallest observations.
