The Solar System G forces function provides the acceleration due to gravity on the 
surface of a planet in our solar system.
INSTRUCTIONS: Enter the following:
- (P) Solar System Object
Acceleration Due to Gravity (g): The calculator returns the acceleration in meters per second squared (m/s2). However, this can be automatically converted to compatible units via the pull-down menu.
The planet list is used to retrieve the acceleration due to gravity (g) on the surface of that planetoid object. This list includes: The solar system
- g(Sun) = 274 m/s2
- g(Mercury) = 3.7 m/s2
- g(Venus) = 8.87 m/s2
- g(Moon) = 1.62 m/s2
- g(Earth) = 9.80665 m/s2
- g(Mars) = 3.71 m/s2
- g(Jupiter) = 24.79 m/s2
- g(Saturn) = 10.44 m/s2
- g(Uranus) = 8.87 m/s2
- g(Neptune) = 11.15 m/s2
- g(Pluto) = 0.62 m/s2
Acceleration Due to Gravity (g)
Gravity is one of the four known forces (weak and strong nuclear forces, electromagnetism and gravity). The acceleration due to gravity is different based on the mass of the star, planet, moon or asteroid and the distance from its center of mass and its surface. For that reason, gravity has a lesser pull on bodies of lesser mass or density than the Earth such as the moon. The formula for acceleration due to gravity is:
`g = (G*M)/R^2`
Where:
- g is the acceleration due to gravity.
- G is the Universal Gravitational Constant (G)
- M is the mass of the object (e.g. planet)
- R is the distance to the center of mass of the object.
