Does the mass of a planet affect its speed?

Assuming we are talking about the mass of the satellite (and not the mass of the body being orbited), mass does not affect the orbital speed.

What does the mass of a planet affect?

A planet’s size and mass determines its gravitational pull. A planet’s mass and size determines how strong its gravitational pull is. Models can help us experiment with the motions of objects in space, which are determined by the gravitational pull between them.

What determines the spin speed of a planet?

The rotational speed is normally determined by the initial angular momentum when the planet formed, but may also be altered subsequently by large collisions (as for example the collision of the earth with another planet which gave us our moon).

Does the mass of a planet affect its rotation?

The effect of mass may be rather on influencing the size of the radii of planets. Moreover, mass does also influence the strength of the rotational force, torque, which may have played a major role in setting the initial constant speeds of planetary rotation.

Does the mass of a planet affect weight?

The amount of gravity the have depends on their size. So, a small planet has less and larger planet has more gravity. Just like the planets, a person with more mass has more gravity and therefore weighs more.

Does the mass of a planet affect its orbit?

A planet’s mass does not affect a planet’s orbit around the Sun.

How does planet mass affect orbit?

Why does the mass of the planet not affect the orbit?

No, the mass of a body orbiting a second body is irrelevant in determining orbital parameters, as long as the first body is much larger than its satellite. You can see this reflected in Kepler’s third law: The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

Do all planets spin at the same speed?

No. Orbital speed is determined by the mass of the object you are orbiting and your distance from it. All of the planets are orbiting the sun, so the mass is the same, but the distance is different. The further away they are, the slower they go.
