Keplers third law will tell you the radius of the orbit based on this information. "The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit." I'm writing a program to generate solar systems but I'm having trouble calculating the expected temperature of a planet. Inputs: gravitational acceleration (a) I found that we still do not have a calculator that, based on the entered area of the circle, would calculate the radius of that circle. Use the formula to find the radius of a body from its Another method involves studying the motion of moons as they eclipse the planet. EDIT: volume is radius ^ … According to Newton’s law of universal gravitation , the planet would act as a gravitational force (F g ) to its orbiting moon. I have found a formula to calculate this, but I haven't been able to get a remotely correct answer out of it as it doesn't clearly state what units your supposed to use. Escape Velocity / Speed Calculator. Once you have the volume assume its a perfect sphere. Consequently, the proportionality constant is not truly the same for each planet. Our radius of a sphere calculator is a perfect tool that can estimate every parameter of a sphere from just one another quantity. Multiple that mass by 1.02 and solve for the volume.
