Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter

Venus' diameter = 12104km or 0.9488 x Earths

Earth's diameter = 12756km

Mars' diameter = 6794km or 0.5323 x Earths The inner planets are all much smaller than the outer gas planets; Jupiter's diameter = 142,984km or 11.21 x Earths

Why do you compare outer planets to inner planets?

Outer planets and inner planets are compared because they have distinct differences in size, composition, and characteristics. Inner planets are smaller, rocky, and denser, while outer planets are larger, gaseous, and have thick atmospheres. Studying these differences helps scientists understand how planets form and evolve in our solar system.


How do the sizes of the inner planets compare to the sizes of the gas giant planets?

How do the sizes of the inner planets compare to the sizes of the gas giant planet?

The inner planets (Mercury, Venus, Earth, Mars) are much smaller in size compared to the gas giant planets (Jupiter, Saturn, Uranus, Neptune). Gas giants are significantly larger in size because they are primarily made up of gases and have thick atmospheres, whereas the inner planets have rocky surfaces and smaller overall volumes.


How do inner planets compare size?

The inner planets, comprising Mercury, Venus, Earth, and Mars, are relatively small compared to the outer planets. Mercury is the smallest, with a diameter of about 4,880 kilometers, while Earth is the largest of the inner planets at about 12,742 kilometers. Venus is slightly smaller than Earth, and Mars is about half the size of Earth. Overall, these planets are rocky and have solid surfaces, distinguishing them from the larger gas giants beyond the asteroid belt.


Which is not true in the inner planets?

The inner planets are closer to the Sun compared to the outer planets, have solid rocky surfaces, and are smaller in size compared to the outer planets.


How the sizes of the inner planets compare to the sizes of the gas giant planets?

The inner planets (Mercury, Venus, Earth, Mars) are smaller in size compared to the gas giant planets (Jupiter, Saturn, Uranus, Neptune). The gas giants are much larger because they are primarily composed of gas and have thick atmospheres, while the inner planets are rocky and have thinner atmospheres. Jupiter is the largest planet in our solar system.
