Terrestrial planets are small because they are composed primarily of rock and metal, which limits their size and density. They formed closer to the Sun, where higher temperatures prevented the accumulation of lighter gases. In contrast, Jovian planets are large because they formed farther from the Sun, where cooler temperatures allowed them to capture and retain significant amounts of hydrogen, helium, and other gases, leading to their massive sizes and thick atmospheres. This distinction in composition and formation location accounts for the size differences between the two types of planets.

What are the small planets and big planets?
Small planets include Mercury, Venus, Earth, and Mars in our solar system, while big planets include Jupiter, Saturn, Uranus, and Neptune. The small planets are primarily rocky and terrestrial, while the big planets are gas giants composed mainly of hydrogen and helium.
Why have the Jovian planets retained their atmospheres?
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
Do Jovian planets have moons?
Yes a Jovian type planet in another star system can have a moon as big as Mars. As of June 2014, it is unknown if one exists.
Why are terrestrial planets rocky?
nobody really knows. some people think it was the big bang, others think god did it. but i think 2 or more meteors colliding form rocky and rough planets.
Is Pluto a big planet or small planet?
Pluto is relatively small as planets go; it is officially categorized as a dwarf planet.
How are inner planets differ from outer?
The Jovian planets (Jupiter, Saturn, Uranus and Neptune) are composed of gases and pressurized liquids. Whereas, the four terrestrial planets (Mercury, Venus, Earth and Mars) are composed of rock and iron.
Which is not a Jovian planet?
Pluto is the only "planet" that isn't a planet. Well I think that the IAU still have not answered the question WHAT MAKES A PLANET A PLANET? Is it a certain size or something? Comment : The IAU have defined a planet. The definition is mainly about size, but it's not simple: 1) The object must be big enough for gravity to have formed it into a (roughly) spherical shape. 2) The object must be by far the largest object in the neighbourhood of its orbit. Pluto qualifies on 1) but fails on 2). Also, Venus and Mercury are sometimes called "morning stars" or "evening stars", but they are planets.
What are the small planets and big planets?
Small planets include Mercury, Venus, Earth, and Mars in our solar system, while big planets include Jupiter, Saturn, Uranus, and Neptune. The small planets are primarily rocky and terrestrial, while the big planets are gas giants composed mainly of hydrogen and helium.
Why are the outer planets call the gas giants?
The outer planets (with the exception of the dwarf planet - Pluto) are called "gas giants" for two reasons - they are GIANT (in size/mass/gravity etc.) compared to Earth and the inner solar system "rocky" or "terrestrial" planets and are composed mainly of a gaseous atmosphere (with, its hypothesized, a small rocky core at the center).
Why is Pluto not a jovian planet?
It's not even a planet, but a dwarf planet. Jovian Planets are big and not solid.Pluto is a solid object with a relatively thin atmosphere.Pluto is small, smaller than any true planet in the solar system.Pluto is not a planet but a dwarf planet.
What are the 7 big crustal planets?
Solid or terrestrial planets are those whose primary mass is land. The terrestrial planets in the Earth's solar system include Earth, Mercury, Venus, and Mars.
Why have the Jovian planets retained their atmospheres?
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
Are dwarf planets small?
They are small compared to other planets but big compared to us.
Are the inner planets small or big?
Small, considering the rest of the planets. But in actuality they are large. As said before, in accordance with the rest of the planets in our Solar system, yes they are small.
Explain how the inner planets are different from the outer planets?
The inner planets, also called terrestrial planets, are closer to the Sun and have solid surfaces, while the outer planets, known as gas giants, are farther from the Sun and composed mostly of gas. Inner planets are smaller and have higher densities, while outer planets are much larger and have lower densities. Additionally, inner planets have few or no moons, while outer planets have numerous moons.
Which planet is not a terrestrial planet?
The planets that are not classified as terrestrial are Jupiter, Saturn, Uranus and Neptune. If you count Pluto as a planet then it would be a part of that list as well. Mercury, Venus, Earth and Mars are the terrestrial planets. Jupiter, Saturn, Uranus and Neptune are the gas giants. Pluto is a dwarf planet.
Do Jovian planets have moons?
Yes a Jovian type planet in another star system can have a moon as big as Mars. As of June 2014, it is unknown if one exists.
