Yes, but also on its diameter. Or density if you prefer.
yes the earth does have a mass because it also is affected by gravity, the gravity from the sun
Mass is not affected by gravity, so it would have the same mass. Weight, on the other hand, is affected by gravity, and would double when on the planet as compared to when it is on Earth (w=mg, where w=weight, m=mass, g=gravitational acceleration also called strength of gravity)
Weight is affected by gravity, while mass is not. Weight is the force exerted by gravity on an object, and it depends on the mass of the object and the strength of the gravity acting on it. Mass, on the other hand, is a measure of the amount of matter in an object and remains the same regardless of the gravitational field it is in.
The greater the mass the stronger the gravitational pull. You probably mean the "surface gravity". This is also affected by the distance of the surface from the center of the planet or Sun. The strength of the gravity falls in proportion to the distance squared, in accordance with Newton's Law of Gravity.
The larger the planet mass, the bigger force of gravity it has.
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.
Density is not affected by gravity. Density is affected by mass and volume, such that density = mass/volume. Weight, but not mass, is affected by gravity. Weight and mass are not the same thing.
Where there is mass there is gravity.
No that is impossible. Gravity is related to mass, so while a planet still has mass it still has gravity.
The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
No. Weight is affected by gravity.
No mass is not affected by gravity, weight is.
