we don't know yet. there isn't any in the solar system, anyway
Is it the planet Mars.
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.
No. The gravitational pull at the surface of a planet depends on that planet's mass and radius. Jupiter has the strongest gravity of any planet in the solar system: 2.53 times the surface gravity on Earth. Mercury has the weakest surface gravity at just 37% the gravity on Earth.
Gases in the Earth's atmosphere stay close to the surface due to the force of gravity acting on them. Gravity pulls the gases towards the center of the planet, keeping them from escaping into space. The mass of the Earth is sufficient to maintain an atmosphere that surrounds the planet.
The planet with an average surface temperature of 14.6°C is Earth.
No, Earth and Mars are not the same planet. They are two separate planets in our solar system with distinct characteristics, such as different sizes, atmospheres, and surface conditions. Mars is known as the "Red Planet" due to its reddish appearance, while Earth is the only planet known to support life.
The surface area of Mars is 144,798,500 km2. This is about the same as all the above sea-level surface area of Earth.
no planet
venus is a planet that has a hard surface and is about the same size as earth but Jupiter is a gas giant with no hard surface to stand on
The planet with a surface covered three fourths in water and ice is Earth.
No, there is not enough water on Earth to cover the entire planet. The Earth's surface is about 70 water, but most of it is in the oceans, which only cover about 71 of the planet's surface.
The Earth is considered a rocky planet.
