What planet is called earth's twin?
Venus because they are almost the same size!
What plane in our solar system is almost the same size as earth?
I assume you mean "planet". That would be Venus.
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.
Does the moon have the same density than the earth?
no it is about 1/6 the density of the earth
Which planet in our solar system has the greatest density?
Mercury. Whilst it is not the most dense (Earth being the most dense planet of the Solar System), without gravitation compression on the Earth, Mercury would be the most dense. So if Earth was the same size as Mercury, Mercury would be the densest planet. It is also the smallest planet.
What iner planet has same mass as earth?
Venus has almost the same mass as Earth.
What planet is almost the same size as Venus?
Earth.
What planet has the same density to earth?
Mercury is only slightly less dense than Earth.
What planet is twins with earth?
Venus because it is almost the same size as Earth.
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 has almost the same tilt axis as the earth?
Mars
How is the planet Mercury like Earth?
They both have an iron core, and they have the same density.
Which planet has a day almost the same length of time as earth?
mars
What planet is called earth's twin?
Venus because they are almost the same size!
What planet has the greater amount of gravitational force mercury or earth?
it's almost the same ... but earth's is a little bit more
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.
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.
