The order of planets according to their decreasing mass is:
- Jupiter: 1.8986 x 10²⁷ kilograms
- Saturn: 5.6846 x 10²⁶ kilograms
- Neptune: 10.243 x 10²⁵ kilograms
- Uranus: 8.6810 x 10²⁵ kilograms
- Earth: 5.9736 x 10²⁴ kilograms
- Venus: 4.8685 x 10²⁴ kilograms
- Mars: 6.4185 x 10²³ kilograms
- Mercury: 3.3022 x 10²³ kilograms
What determines the weight of an object?
The weight of an object is determined by the mass and the acceleration due to gravity, g.
The greater the value of g, the more the weight of the body and vice versa.
- Weight = mass * acceleration due to gravity
Also, the more massive a planet or star is, the stronger the gravitational force it exerts. However, an increase in the radius of the planet results in a smaller gravitational force.
Thus, the order of planets according to their mass is:
- Jupiter: 1.8986 x 10²⁷ kilograms
- Saturn: 5.6846 x 10²⁶ kilograms
- Neptune: 10.243 x 10²⁵ kilograms
- Uranus: 8.6810 x 10²⁵ kilograms
- Earth: 5.9736 x 10²⁴ kilograms
- Venus: 4.8685 x 10²⁴ kilograms
- Mars: 6.4185 x 10²³ kilograms
- Mercury: 3.3022 x 10²³ kilograms
In conclusion, the greater the mass of a planet, thee higher the weight of objects on its surface.
