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.

The range is the difference between the largest and smallest observations.
The correct order from smallest to largest is: asteroid, comet, meteorite, planet, star, solar system, galaxy, and universe.

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

The order from largest to smallest would be: star, galaxy, planet, filament. Stars are individual astronomical objects, galaxies are collections of stars, planets are celestial bodies in orbit around stars, and filaments are structures in the cosmic web that connect galaxies.

It is yet unknown, as we haven't even explored 1% of our own galaxy, let alone the whole universe.
