Which class of objects in Solar System carries more mass? Could you help me sorting this list in terms of total mass carried by these classes of objects?


The star (Sun) - it's very big but only one.
The planets (incl. dwarf planets). Certainly beaten by the Sun, but...
the asteroids, meteorites, comets, all that rubble. They aren't heavy individually but there's a lot of them.
the interplanetary medium. It's very low density, but it overshadows the rest by far in terms of volume occupied.


I'm not sure where to attach the moons - some of them are larger than some dwarf planets, some are definitely more asteroid-sized. I guess - whoever decides to answer this, is free to pick where they'd like to include the moons (or maybe to split them between the two classes, say, attaching the ones with hydrostatic equilibrium to dwarf planets, and bundling the rest with the rubble)?
The sun by far occupies the largest part of the solar system's mass. The mass of the sun happens to be approximately $(1.98855±0.00025)×10^{30}$ kg. Which is immensely huge. By comparison the inter-planetary medium though may occupy a large volume is nowhere dense enough to even compare to the mass of the sun which is approximately 99% of the solar system's mass.

The mass of all planets combined by comparison happens to be approximately $2.6634×10^{27}$kg.
As far as interplanetary matter is concerned, its density is to low and its volume is pretty hard to define so mass remains a highly variable quantity.

Moons and asteroids account only for a fraction of the mass of the solar system though they happen to be present in large numbers.
