What is the value of gravitational field strength on a planet with half Earth's mass and half its radius?
The value of the gravitational field strength on a planet with half the mass and half the radius of Earth would be the same as Earth's gravitational field strength. This is because the gravitational field strength depends only on the mass of the planet and the distance from the center, not on the size or density of the planet.
Which planet is closest in mass to the size of planet Earth?
Venus is the planet closest in mass to Earth, with a mass about 81% that of Earth.
Which planet most like earth in size and mass?
Venus is closest to the Earth in size and mass. Its diameter is around 95% of Earths, while its mass is around 81.5% of Earths.
What planet is 300 times size of earth?
No planet is. Jupiter, however, is 318 times the mass of Earth.
Which planet is most like earth in size and mass?
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.
What is the planet in the solar system that is half the size of earth?
Mercury
What planet similar to each other in size and mass?
venus and earth
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.
Is the moon half the size if the earth?
The moon is not half the size of the earth. the earth has a mass of 3.98 X 1024 kg, and the moon only has a mass of 7.34 X 1022 kg, which is only about 0.012300 Earth masses.
Is mars a large and gaseous planet?
No, Mars is only about half the size of Earth and it is a solid, rocky planet.
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 planet is most similar to the earth in size volume mass density?
Venus is the planet most similar to Earth in size, mass, volume, and density. It is often referred to as Earth's "sister planet" due to these similarities despite having a very different atmosphere and surface conditions.
