yes the earth does have a mass because it also is affected by gravity, the gravity from the sun
If you're the same distance from the center of the planet but its mass is greater than earth's mass, then the mutual gravitational force between you and that planet is greater than on earth, and you'll "weigh" more than you do here.
There isn't. The "surface gravity" is dependent on the mass (of the planet, etc.) and the distance of the surface from the center of mass. Pluto has MUCH LESS mass than Earth and the gravity is much less on Pluto.
The hydrosphere, which is the combined mass of water on, under and around a planet.
The Thundercats hail from the planet of Thundera (spelled ThunDERa in all of the officially released Thundercarts books of the period). The planet was destroyed, hence why the inhabitants had to make a mass exodus. Most of the ships carrying the refugees were destroyed but the Nobles of Thundera made it to a small planet called Third Earth (which in a Wildsorm comic, was revealed to be Earth in the future)
We are called Earth. "Blue Planet" is a nickname for Earth, since our planet comprises primarily of water.
The mass of planet Earth is 5.9736 × 1024 kg
Venus at 81.5% the mass of Earth.
Earth's Mass is 17 times less than neptune's mass.
Venus
Venus has almost the same mass as Earth.
Jupiter has the greatest mass relative to Earth.

Your weight is directly proportional to the mass and gravity of the planet, if the planet has a greater gravity and mass, you will weigh more.
The planet Venus is closest in size and mass to planet Earth. It is only slightly smaller and roughly four-fifths of Earth's mass; for this reason it is sometimes referred to as Earth's twin or sister planet.
Venus, with a mass of 0.815 that of Earth, and a diameter of 0.949 that of Earth.
