Solar system by size from 1,000 km to 1 million km radius. (1 billion cu km (1 Zl) to 1 quintillion cu km (1 Dl)
The ordering may be different depending on whether one chooses radius or mass, because some objects are denser than others. For instance, Uranus is slightly larger than Neptune but less massive. Neptune is more massive and denser than Uranus, And although Ganymede and Titan are slightly larger than Mercury, they have less than half Mercury's mass. Titan is actually only 30% as massive as Mercury. This means some objects in the lower tables, despite their smaller radii, may be more massive than objects in the upper tables because they have a higher density.
There are not all solar system objects, but the basic objects we need to know and study most.
