What planet has almost the same density as earth?
it is mars it has water
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.
How is the planet Mercury like Earth?
They both have an iron core, and they have the same density.
What is the density of the planet Saturn compared to the planet Earth?
Earth's density: 5520 kg/m3 Saturn's density: 690 kg/m³
Why cant the same planet have lots of mass and density?
We think it can. The earth's average density is more than 5.5 times the density of water, which we think qualifies as "lots of density". Also, the earth has a mass of 5,970,000,000,000,000,000,000,000 kilograms, which we really think is lots of mass.
The Moon's average density is about the same as the density of which of the Earth's layers?
The moon's average density is about the same as the density of mantle of the Earth.
Which inner planet has the greatest density?
The Earth has the greatest average density, of all the planets.
What planet is the same as the planet earth?
no planet
The Moon's average density is about the same as the density of earth's layers?
You are correct! This is the reason why many scientists believe that the moon was once long ago part of the earth, that an asteroid possibly dislodged, or the roation of the earth spun off a piece of the planet.
If a planet has 4 times the density but half the diameter of earth is it's gravity stronger or less?
No, the gravity of this planet will not be greater than that of earth. If the new planet has a mass equal to that of earth, its total gravity will be the same. There is a little ambiguity regarding 4 times earth density and half the earth's diameter if the idea is to keep the mass of this proposed planet the same as the earth. But setting that aside and assuming that the mass of the new planet is the same as earth's, the gravimetric field will be the same. Gravity is proportional to mass, and identical mass yields identical gravity. Now to the good part! The surface gravity of the new planet will be considerably higher than the surface gravity of earth. Both planets have the same mass and the same gravity, but a person standing on the surface of the new planet will be experiencing a whole lot more force pulling on him. All the mass of the new planet is beneath this person, but he's a lot closer to the center of gravityand will weigh a whole lot more.
What planet is most dense Mercury Venus or earth?
Earth, with a density of 5.515 gr/cm3, it is the densest planet in the solar system.
Does the moon have the same density than the earth?
no it is about 1/6 the density of the earth
