Do planets with same mass have same gravity?

Explanation: The gravity of a planet, or other body, is proportional to its mass. The density of the Earth is about 5.51 g/ cm3 . A planet with double the volume of the Earth would have to have half the density to have the same mass and hence the same gravity.

Do bigger or smaller planets have more gravity?

The heavier a planet is, the more gravity it has, and since all jovian planets have more mass than terrestrials, hence they have more gravity. The gravitational pull between two bodies is proportional to the mass of either body and inversely proportional to the square of the distance between them.

What two planets have the same mass?

Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity. However, your mass is the same everywhere!

Do smaller planets have more mass?

But a planet’s size is not necessarily proportional to its mass. So while a planet like Mercury may be smaller in size than Jupiter’s moon Ganymede or Saturn’s moon Titan, it is more than twice as massive than they are.

Which planet is almost of same size and mass of the Earth?

Venus is sometimes called Earth’s twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets. However, Venus and Earth are also very different.

Could a planet be smaller in size than Jupiter but greater in mass?

Yes, a planet could be smaller in size but greater in mass than Jupiter because the more gas that is added, its weight would compress the interior enough to make it smaller. Briefly describe the interior structure of Jupiter and why it is layered in this way.

Do small planets have less gravity?

According to certain laws of physics and the universe, all mass has a gravitational pull. Following that rule, then the answer is simple: Smaller planets have less gravity because they contain lesser amounts of mass [on average].

Can a smaller planet have higher gravity?

If the planet’s density is ρ, then its mass is proportional to ρr3, so the gravity at the surface is proportional to ρr. Therefore, if you want a smaller planet than Earth to have higher surface gravity, you’re going to need it to have higher density.

What planet has the smallest mass?

Mercury is the smallest planet in the solar system, named after an ancient Roman god, known for speed and commerce….The Smallest Planet In The Solar System – Mercury.

Equatorial Circumference	15,329 km
Mass	330,104,000,000,000 billion kg (That is 5.5\% of Earth)

How does the mass change on larger vs smaller planets?

The amount of gravity the have depends on their size. So, a small planet has less and larger planet has more gravity. Just like the planets, a person with more mass has more gravity and therefore weighs more.

Which planet has the smallest mass?

Which two planets are most alike in size mass and density?

Venus and Earth are often called twins because they are similar in size, mass, density, composition and gravity. Venus is actually only a little bit smaller than our home planet, with a mass about 80\% of Earth’s. The interior of Venus is made of a metallic iron core that’s roughly 2,400 miles (6,000 km) wide.

Do two planets with the same mass have the same gravity?

By this definition, a very sensible, useful, one, two objects with the same mass, whatever their density will bend space to the same degree and so gravity is the same. However, if two planets have the same mass but one is less dense than the other, the less dense one must be bigger.

What is the mass of a human on other planets?

Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity. However, your mass is the same everywhere!

What is the size of the other planets in the Solar System?

Planet Sizes. Mercury – 1,516mi (2,440km) radius; about 1/3 the size of Earth. Venus – 3,760mi (6,052km) radius; only slightly smaller than Earth. Earth – 3,959mi (6,371km) radius. Mars – 2,106mi (3,390km) radius; about half the size of Earth. Jupiter – 43,441mi (69,911km) radius; 11x Earth’s size.

How big is Saturn compared to other planets?

Saturn: However, it is significantly less massive than its Jovian cousin, with a mass of 569 x 10 24 kg (or 569,000,000,000 trillion metric tons). Still, this makes Saturn the second most-massive planet in the Solar System, with 95 times the mass of Earth.
