Is titan larger or smaller than earth?
Titan is the largest moon of Saturn. Smaller than the earth it is, however, larger than the planet Mercury though has less mass
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.
Which of these planets is closest insize to earth?
The planet Venus is closest in size and mass to planet Earth. It is only slightly smaller and roughly four-fifths of Earth's mass; for this reason it is sometimes referred to as Earth's twin or sister planet.
How much does Mercury weigh?
The planet Mercury has no weight, as this would be expressed within a gravitational field. The mass of Mercury is estimated as 3.3 ×10²³ kilograms (only about 5.5% of Earth's mass).The element Mercury has a density of 13.5 grams/ml (13.5 grams/cm3).
Does mercury have more gravity than earth?
Gravity behaves exactly the same on Mercury as it does on Earth. The forces between Mercury and any other mass are proportional to the product of Mercury's mass and the other mass, and inversely proportional to the square of the distance between Mercury's center and the other object's center. Mercury's size is about 38% as big as the Earth's size, which would place the center of an object on its surface closer to the planet's center, and cause a greater gravitational force. But its mass is only 5.5% of Earth's mass. So the force of gravity between Mercury and an object on its surface winds up being only about 37% of the gravitational force on the same object when it's on Earth's surface. That means that a person who weighs 100 pounds on Earth would weigh 37 pounds on Mercury.
Which planet is smaller than Ganymede?
Ganymede is largerthan Mercury, but has a smaller mass.
Is titan larger or smaller than earth?
Titan is the largest moon of Saturn. Smaller than the earth it is, however, larger than the planet Mercury though has less mass
Which planet is 5.5 percent of Earth's mass and has no moon?
Mercury
Which planet is the lighest weight?
Mercury is the lightest planet, with a mass of 0.055 that of Earth.
How much bigger is mercurys mass than earth?
Mercury has a mass of 0.33x1024kg, and Earth has a mass of 5.97x1024kg. Thus, Mercury has a smaller mass than earth (or, in other words, Earth has a mass that's about 18x greater than that of Mercury).
Which planet is 5.5 percent of Earth and mass and has no moon?
Mercury

What planets have a mass smaller than earth?

Which planet has a mass about half the size of earth?
None in our solar system. Mars and mercury are much smaller and Venus is about the same size - a bit smaller. The four gas giants are all much bigger.
Which of these planets is closest insize to earth?
The planet Venus is closest in size and mass to planet Earth. It is only slightly smaller and roughly four-fifths of Earth's mass; for this reason it is sometimes referred to as Earth's twin or sister planet.
Which planet has a larger mass than earth?
All of them except Mercury, Venus, and Mars.
