Gaseous
Saturn is gaseous.
It is terrestrial.
It's a terrestrial planet
Jupiter is the first of the gaseous (Jovian) planets and Mars is the last terrestrial one.
The Earth is terrestrial rather than gaseous. There are several planets in the solar system that are considered to be gaseous but the Earth and Mars and even Pluto are terrestrial.
Venus is a terrestrial planet.
Gaseous planets include Jupiter and Saturn, while terrestrial planets include Mercury, Venus, Earth, and Mars. Gaseous planets are primarily composed of hydrogen and helium, with no solid surface, whereas terrestrial planets are rocky, with a solid surface.
Neptune is a Jovian planet. Which means it is a gas giant.
The "terrestrial planets" are rocky and the "gas giant planets" are gaseous.
It is terrestrial. The terrestrial plants are: Mercury Venus Earth Mars Pluto (if you still pretend it's planet. I do!) The gaseous are: Saturn Jupiter Neptune Uranus
I'm assuming you mean "Is Jupiter a terrestrial or gas planet?" It is a gaseous planet.
