which objects are listed in order from smallest to largest in the soloar system?

Answer 1

All of them, if you have enough time.
;-)

The list will have the following categories (I begin with the largest = more massive)

a) The Sun (it has someting like 98% of the mass of the solar system)

b) the Gas giants (planets)

c) the "terrestrial planets"

d) the bigger satellites (our Moon, Galilean satellites of Jupiter, Titan...), some of them mixed in with the terrestrial planets (Mercury is kind of small).

e) the dwarf planets (also mixed in with some of the bigger moons).

f) the minor planets (although we are discovering smaller and smaller ones, down to less than 1 km across); there are millions.

g) the smaller satellites.

h) comets (the nucleus of Halley's comet was measured as 15 km long, most are smaller)

i) meteoroids (small pebbles): we normally can't detect them but we can reconstruct the main streams after observing meteor showers.

j) dust (the dust in the system's plane can be visible on very dark evenings as "Zodiacal light")

k) gas (individual molecules, some of them ionised)

l) solar wind and cosmic rays (individual atoms, usually ionised)

m) neutrinos (motly from the Sun's core)

n) photons
