Mass of Planet X divided by volume of Planet X No, the mass of a planet does not equal the size of that particular planet.  The mass of planet Earth is 5.9736 &Atilde;&mdash; 1024 kg  The larger the planet mass, the bigger force of gravity it has. Your mass does not change. Your weight, however, changes in proportion to the gravity of each planet. The mass of a planet is measured based on the effects of its gravity on nearby objects. Jupiter has is the planet in our solar system with the most mass Every planet has gravity because every planet has mass. Escape velocity depends on mass. The planet with the lowest mass is Mercury. The gravitational force on an object at a standard distance is proportional to the mass of the planet.  A more massive planet is attracted more by the Sun if other things like the distance are equal. The force of gravity on a planet is proportional to the mass of the planet and inversely proportional to the sare of the distance. The greater the mass of a planet, the greater will be its gravity. Weight is the measure of mass of an object under the force of gravity. No planet is considered a star! Any burning mass is a star, such as the sun or OGLE-TR-122b. A planet is a solid mass.  The gravitational force on an object at a standard distance is proportional to the mass of the planet. The majority of the mass in the solar system is contained in the sun, which is a star, not a planet. The Majority of the mass in the solar system outside of the sun is contained in the planet Jupiter. Gravity comes with mass so since a planet has mass there is some gravity. the bigger the planet the more mass it has. smaller planets have less gravity. so either way there is always some gravity on a planet. The strength of gravity of an object is directly proportional to its mass. A larger planet will generally have a greater mass.  it is exactly the same as a planet but its diameter and mass are not great enough to be considered a planet. Your mass does not change no matter which planet you're on. That is because mass is a measure for how much material there is. However, your weight will change because it is the measure of how much you're being pulled down by a planet.
