# How much mass was there in the protoplanetary disk out of which the planets formed, compared to the mass of the Sun?

The mass of the protoplanetary disk was about $2 \cdot {10}^{30} K g$, the mass of the Sun is about $1.989 \cdot {10}^{30} K g$.
The mass of the solar system, and hence the protoplanerary disk, is about $2 \cdot {10}^{30}$Kg. The Sun at $1.989 \cdot {10}^{30} K g$ contains 99.89% of the solar system's mass.
Of the remaining mass the four gas giants Jupiter, Saturn, Uranus and Neptune make up 99%. The other 1% is the combined mass of the rocky planets, asteroids, comets and dust and gas.
