The best answer to the question as stated is "no".

Until recently, in the only planetary system we had any knowledge the inner planets as rocky, and that led to the conjecture that proximity to the central star would drive away most of the gas and prevent gas giants from forming there.

We now know that "hot Jupiters" are surprisingly common, and it may just be a coincidence that, in the Solar system, the inner planets happen to be rocky.

However, while the inner planets in the Solar system are rocky, they are not "large"; the largest of the inner planets is 5th in a system of 8 ... and it's not a close 5th, either. The smallest of the outer planets is many times larger than the largest of the inner planets.

Do inner planets have rocky surfaces?

Yes, inner planets like Mercury, Venus, Earth, and Mars have rocky surfaces. These planets are primarily composed of silicate rocks and metals, with solid surfaces that are differentiated into crusts, mantles, and cores. The rocky surfaces of these inner planets differ in terms of composition, age, and geologic processes that have shaped them over time.

Are the inner planets rocky or gassy?

The inner planets (Mercury, Venus, Earth and Mars) are rocky. It is the outer planets (Jupiter, Saturn, Uranus and Neptune) that are gas planets.


How do the surface materials of the inner and outer planets differ?

The inner planets (Mercury, Venus, Earth, Mars) have rocky surfaces composed of silicate minerals and metals. The outer planets (Jupiter, Saturn, Uranus, Neptune) have gas surfaces, primarily composed of hydrogen and helium. Additionally, outer planets may have icy surfaces due to the presence of water and other ices.
