The order from largest to smallest is universe, galaxy, star, and planet. The universe encompasses everything, including galaxies like the Milky Way. Within galaxies, there are stars like our sun, and planets like Earth.
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.
Planet Solar System Galaxy Universe
The universe is organized in a hierarchical structure from largest to smallest as follows: universe, observable universe, galaxy, solar system, planet, moon, and then down to subatomic particles like protons, neutrons, and electrons.
Jupitor is the biggest planet and our galaxy is the a spiral galaxy:)
As of June 2014, Mars is the seventh biggest planet in the universe. The sie Mars is approximately 53% the size of the Earth.
In short it's the Sun but you probably didn't mean that. A dwarf planet like Pluto is among the biggest, or perhaps Saturn's moon Titan.
Ganymede, which is one of Jupiter's moons, is the largest moon in our solar system. It is even bigger than the planet Mercury.
