inner planets are small and outer planets are big and cold and gas giants.
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.
they are small
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.
The sizes of inner planets are generally smaller compared to the sizes of the gas giants. The inner planets are Mercury, Venus, Earth and Mars. The gas giants are Jupiter, Saturn, Uranus and Neptune.
The average terrestrial planet has only about 10.3% of the diameter and 0.4% of the mass of the average gas giant.
they are all different sizes
The inner planets, which include Mercury, Venus, Earth, and Mars, are significantly smaller and rockier compared to the outer planets. The outer planets—Jupiter, Saturn, Uranus, and Neptune—are much larger and predominantly composed of gases and ices. For instance, Jupiter, the largest planet in the solar system, is more than 11 times the diameter of Earth, showcasing the stark contrast in sizes between the two groups. Overall, the inner planets are termed terrestrial, while the outer planets are known as gas giants or ice giants.
The inner planets (Mercury, Venus, Earth, Mars) have more in common with each other compared to the outer planets (Jupiter, Saturn, Uranus, Neptune). The inner planets are often referred to as terrestrial planets and are characterized by their solid surfaces and relatively small sizes, while the outer planets are gas giants with no solid surface and much larger sizes.
The Inner Planets are also known as the terrestrial planets or rocky planets. They include Mercury, Venus, Earth, and Mars, and are characterized by their solid surfaces and relatively small sizes compared to the outer gas giants.
The inner and outer planets are alike in that they are all part of our solar system and orbit around the Sun. They also have varying sizes and compositions, with the inner planets being smaller and rocky while the outer planets are larger and gaseous. Additionally, they all have moons, but the outer planets tend to have more and larger moons compared to the inner planets.
Shape, rotation-direction, and orbit-direction.
The giant planets are primarily composed of hydrogen, helium, and other gases. This composition gives the planets their low densities and large sizes compared to terrestrial planets. Additionally, these planets may have a small rocky core at the center, surrounded by layers of gas.
