Use the formula to find the radius of a body from its gravitational acceleration and the gravitational constant (all bodies have gravity that is proportional to their mass).

See related links for a web page that will do the calculations for you.

How do you find the volume of a planet?

To find the volume of a planet, you can use the formula for the volume of a sphere: V = 4/3 * π * r^3, where r is the radius of the planet. You would need to know the radius of the planet to calculate its volume.

How can one determine how to find escape velocity in a given scenario?

To find escape velocity in a given scenario, you can use the formula: escape velocity square root of (2 gravitational constant mass of the planet / radius of the planet). This formula takes into account the gravitational pull of the planet and the mass and radius of the planet. By plugging in these values, you can calculate the escape velocity needed to leave the planet's gravitational pull.

What is the weight of an object on the surface of a planet with radius r?

The weight of an object on the surface of a planet with radius r is determined by the planet's mass and the object's distance from the planet's center. The weight can be calculated using the formula W (G M m) / r2, where W is the weight, G is the gravitational constant, M is the planet's mass, m is the object's mass, and r is the radius of the planet.
