Which planet is closest to Earth in size gravitational strength and composition?

The planet Venus is sometimes called "Earth's Twin" or the "failed Earth" because it apparently began very much like Earth although it is only two-thirds as far from the Sun. Venus has a diameter that is 95% that of Earth, a gravity that is 90.4% of Earth's at its surface, and a similar composition in elements.
However, owing to its closer orbit, and to a runaway greenhouse effect, practically all of the water is gone from Venus, and as a result almost all of its primordial hydrogen. The majority of the oxygen in the atmosphere exists as carbon dioxide.

What planet in known has ''earth's twin''?
The Planet Venus, since it is of a similar size and composition. It is also the planet which comes closest to earth.
What planet is closest to earth in gravitational strength?
That is Saturn. For example, if you weigh 100 pounds on Earth, you would weigh 106.4 pounds on Saturn.
What 2 factors would affect how thick a planet's atmosphere is?
The strength of the planet's gravitational field and exposure to solar wind.
When will a planet travel fastest in its orbit?
The earth is moving fastest in its orbit at the moment of perihelion, when it is closest to the sun. the happens around January 3.
How do planets orbit closest to sun?
it uses gravity. The sun has a gravitational pull, so it keeps the closest planet close to it. the farther away a planet is, the weaker the gravitational pull. Without it the planets would "drift" off from the sun. Plus all the moons wouldn't orbit us anymore. -----CMH
What does the gravitational field strength on a planet depend on?
It can be calculated on the basis of the planet's mass and its radius.
What planet is Jupiter's chemical composition closest to?

What is the relationship between the mass of the planet and the relative strenghth of its gravitational pull?
The relative strength of its gravitational pull is directly proportional to the planet's mass.
Why there will be a point between the earth and the moon at which the gravitational field strength will be zero?
There is a point where the gravitational field strength of both planet or object is equal, hence they cancel off each other, resulting in zero net gravitational field strength.

Does planet mars have gravitational pull?
Yes. It's about 38% of the strength of Earth's gravity.

What is the gravitional field strength of the earth at its surface?
The gravitational field strength of a planet multiplied by an objects mass gives us the weight of that object, and that the gravitational field strength, g of Earth is equal to the acceleration of free fall at its surface, 9.81ms − 2.

What is the value of gravitational field strength on a planet with half Earth's mass and half its radius?
i guess it 's 39.2n.kg
