It is important because if there's know land there they might land and a dangerous place.
because
The Jovian planets are gas giants and have no surface.
The inner planets' surface materials differ from the outer planets because the inner planets have rocky surfaces and the outer planets have gas surfaces.
the surface is solid
The inner planets are all considered rocky planets in that under atmospheric layers, they have a rocky surface. The outer planets are made of gas and liquid, and are called gas giants. They have no solid surface. Also, all the outer planets have rings while the inner planets do not.
The inner planets, except earth, are made up of rocks. They have a hard surface. The earth would be one of these except we have water. The outer planets are gas giants and do not have a solid surface.
The Jovian planets are gas giants and have no surface.

There are two primary outcomes from the Apollo 11 mission. The first, and most important, was that man could travel to the moon, land on its surface, get out and walk around on its surface without sinking under the soil (a real concern many held prior to launch), get back into the spacecraft, rendezvous with the orbiting Command Module, and return safely to Earth. That was the primary, and most important goal, of the Apollo 11 mission. Less important, at least for this mission, was the return of samples and pictures and the placement and execution of some small science experiments on the lunar surface. These were all performed, and the science was important, but it was not the primary goal of the mission.
the surface is solid
Jovian Planets do not have a solid surface to stand on.
Of all the planets the surface of Mars is closest to being like Earth.
None of them do. All the outer planets are gas planets while all the inner planets are rocky. You might be thinking of Pluto. It has a solid surface, but it is no longer considered a planet.

The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.
ans2, There are as many atmospheric and surface compositions as there are planets with atmosphere or surface.You'll have to be more specific if you want useful data.
