No. The planets vary greatly in both size and mass.

What planet similar to each other in size and mass?
venus and earth
Does the mass of a planet equal the size?
No, the mass of a planet does not equal the size of that particular planet.
Why do planets move faster than on another?
the galaxy has difrent kinds of mass arouund each planet depending on what planet you are speaking of, it might be because of mass of the planet or what size a revolution (size of a complete circle) it must make
Would a smaller planet than earth with the same shape and size have more gravity?
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
What planet is very much like earth?
Venus. Earth and venus are virtually the same size and have the same mass.
Which planet is same size as Uranus?
Neptune is the closest in radius to Uranus, at about 740km or 3% smaller.
Which planet is considered to have the most similar atmosphere to our planet?
no planet has an atmosphere like ours! Sorry! Fun Fact: Venus is the same size and mass as Earth!
Which planet is closest in mass to the size of planet Earth?
Venus
The size of a planet's orbit is determined by?
The mass of the planet, the mass of the sun and the distance between the two.
What moon is almost the same size as the planet?
There is no planet that has the same size moon as the planet. This is only possible if Pluto was still a planet.
How does a planet's size affect its gravity?
The distance between a planet and an object affects the gravitational force between them. That means the size of a planet affects the value of the "surface gravity" for that planet. The greater thedistance from the surface to the center of the planet, the smaller the gravity at the surface (for the same planet mass). An example is the fact that Mars and Mercury have almost exactly the same surface gravity. Mars has more mass than Mercury, but this is balancedby the fact that Mercury hasthe smaller radius.
Why is why is there gravity on some planets but not on others?
There is gravity on all planets. The strength of that gravity varies depending on the size and mass of each planet.
