Worlds of The Solar System


Following list contains all bodies of our Solar System photographed from close range at satisfying resolution (+ several poorly resolved bodies + growing number of asteroids imaged by ground-based adaptive optics + few farout smudges captured by Hubble + some other notable objects) sorted roughly by size:

1 Main sequence star   4 Giant gaseous planets   4 Big rocky planets   7 Large planetary moons   3 (+9) Dwarf icy planets   11 Round icy moons   1 (+10) Transitional planetoids     2 (+2) Big irregular moons   0 (+21) Big Main belt asteroids   0 (+4) Centaurs   4 (+4) Medium irregular moons   0 (+8) Jovian trojans and their satellites   4 Medium Main belt asteroids   1 Small Kuiper belt object   12 (+6) Small irregular moons   2 (+4) Small Main belt asteroids and satellites   4 (+2) Comets   7 (+14) Near-Earth asteroids and satellites

67 (+84) = 151 objects in total
Many more objects are mentioned just by name or overall population in each category.

Other way to sort the worlds is by the realm which they occupy:
