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 Dense rocky planets   7 Large planetary moons   3 (+9) Dwarf icy planets   11 (+1) Round icy moons   0 (+6) Kuiper belt planetoids     1 (+2) Main belt planetoids     2 (+2) Transitional moons   0 (+20) Big Main belt asteroids   0 (+4) Centaurs   4 (+4) Big irregular moons   0 (+8) Jovian trojans and their satellites   4 (+2) Medium Main belt asteroids   8 (+4) Medium irregular moons   1 Medium Kuiper belt object   2 (+4) Small irregular moons   4 (+8) Small Main belt asteroids and satellites   4 (+4) Comets   7 (+13) Near-Earth asteroids and their satellites

67 (+91) = 158 objects in total
Many more objects are mentioned just by name (117) or overall population in each category.

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