The three qualifications for a planet are:
1. It orbits the parent star.
2. It has hydrostatic equilibrium (roughly spherical shape) caused by the gravitational forces.
3. It has cleared its path of orbital debris. (This one is hotly contested.)
The earth or a planet that resembles the earth in its physical characteristics. The terrestrial planets in the solar system are the earth, mercury-in-roman-religion-planet-nearest-to-the-sun, venus, and mars. These planets are approximately the same size, with the earth the largest. They are considerably denser than the jovian-planet, ranging from a specific gravity of 4 for Mars to 5.5 for the earth. Because they spin less rapidly than the Jovian planets, the terrestrial planets are less flattened at their poles.
The elements of Terrestrial Planets are made up of rocky ground or land, as distinct from water or air.
They are also planets nearest our sun ,Venus,Mercury or Mars that resemble Earth in substance and density
IT HAS TO HAVE . . . A SPHERE SHAPED BODY IT HAS TO BE AN INNER OR AN OUTER PLANET ORBITS THE PARENT STAR IT'S CLEARED IT'S SPOT OF ORBITACLE DEBRIS. IT HAS HYDROTASTIC EQUILIBRIUM (Roughly spherical shape)CAUSED BY THE GRAVITATIONAL FORCES.
Made of solid material, small, closest to sun.
1. rocky
2. Gassy
3. Stupid
4. Dumb
5. You love men
They are in direct orbit around the sun, they are large enough to be approximately spherical (achieving hydrostatic equilibrium) and have cleared their orbit of other major bodies.

This is impossible to answer for a planet with unknown conditions or characteristics.
The force due to gravity of a planet is dependent on the mass of that planet (and to a lesser extent the radius/diameter). If a planet is less massive then it will have a lower gravitational force.
Pluto has three moons but is no longer classified as a planet.
Saturn fits into all three categories
Venus.

I dont know. planet earth is mistory
One of the characteristics are that it is the only planet that humans can survive on.
its a red planet
