Where is 99% of the mass of the Solar System?
By far most of the solar system’s mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star.
What makes up 99.9% of the mass of the Solar System?
The Sun contains about 99.9 percent of all the mass of the solar system.
How much does each planet weigh?
What is the mass of the other planets in our solar system?
| Planets (in order of least massive to most massive) | Mass (in kilograms) | Each planet’s mass relative to Earth |
|---|---|---|
| Earth | 5.97 x 1024 | 1 |
| Uranus | 8.68 x 1025 | 14.5 |
| Neptune | 1.02 x 1026 | 17.1 |
| Saturn | 5.68 x 1026 | 95.2 |
How do you find the mass of a planet?
The most accurate way of measuring the mass of a planet is to send a spacecraft to it and measure the acceleration due to gravity as the spacecraft passes by it. Alternatively, if the planet has a moon then its mass can be calculated from the moon’s orbit.
How many kg is the Sun?
Bulk parameters
| Sun | Ratio (Sun/Earth) | |

How much of our solar system mass is in the Sun?
99.8%
Most of the nebula’s material was pulled toward the center to form our Sun, which accounts for 99.8% of our solar system’s mass. Much of the remaining material formed the planets and other objects that now orbit the Sun.
How heavy is the Sun?
1.989 × 10^30 kgSun / Mass
What percent of mass is the sun?
It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
How is planet mass calculated?
Yes. The masses of the planets are calculated most accurately from Newton’s law of gravity, a = (G*M)/(r2), which can be used to calculate how much gravitational acceleration (a) a planet of mass M will produce on objects at distance r away. One can solve for M once the other numbers are known.
