Really none, there is no actual planet that has the exact same gravity, some can be close, like saying it Gforce was 2000, and another was 2000, but actually its like 2000.01010203053232 and 2000.21020103020310.
Mars and Venus are roughly the same size as earth (and thus have about the same gravity), but I don't think any planet in our solar system is exactly the same as earth. Gravity is determined by mass; the planet in our solar system with a mass closest to earth is Venus.
Venus' gravity is 8.87 ms-2 whereas the Earth's gravity is 9.86 ms-2. Mars's gravity is 3.71 ms-2.
No, the force of gravity depends on the mass of the planet and also on how far you are from its centre. The force is proportional to the mass and inversely proportional to the distance-squared.
Because gravity is based on mass, a planet that has similar to Earth's would be one that has about the same mass as Earth, like Mars or Venus.
The closest would be Venus. Earth has an equatorial surface gravity of 0.99732g whilst Venus has 0.904g
The earth is the most dense planet at 5.515 g/cm3, but Mercury comes close at 5.43 g/cm3
No known planet has the exact same gravity as Earth does, but Venus comes pretty close. Its gravity is about 90% what it is at Earth's surface.
The Sun's gravity keeps the planets orbiting the Sun.
Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.
The actual number of planets similar to the earth will likely never be known. The universe is simply too vast. However, it is likely that there are millions of similar planets.
Earth technically has a weak gravity because it is one of the smallest planets compared to the others. The greater the size or mass the more gravitational pull it has.
gravity is something that can affect the planets.
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
The Sun's gravity keeps the planets orbiting the Sun.
Neptune and Jupiter
the suns gravity pull creates the earths movement as well as the other planets
About 0.183g, where one g is the earths gravity, so about one fifth of the earths gravity. It is similar to our own moons surface gravity.
No.
earths rotation around the sun
Of the four inner, rocky planets, Earth is the largest and most massive. As a consequence, it has the highest surface gravity of the four inner planets. The gravity for Venus is around 90% of Earths, while for Mars and Mercury the surface gravity is around 38% of Earths.
Generally gravity of other planets, moons, ext is compared relatively to Earth's (with Earth's being 1).
Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.
Mars has a very similar angle of axial tilt to Earth.
Planets with a smaller surfae gravity than Earth are Mercury, Venus, Mars, and Uranus.
