The outer planets are gas giants, made mostly or entirely of gas, so either there is no surface to land on, or even if there is, it lies underneath such a large amount of atmosphere that the atmospheric pressure would crush any spaceship that tried to land there. However, the outer planets also have lots of moons, which would be very suitable places for spacecraft to land.
It would be a list of the outer planets.
I think you mean closeST to the Sun! Inner planets- these in our own solar system would include Mercury, Venus, our own Earth, and Mars.
I guess that would be Mars, which has an orbit outside the Earth's orbit. The first four planets have solid cores, while the four outer planets are gas giants.
In order to land on a planet, it has to have a solid outer crust. The only planets in the solar system with a solid outer core are the 4 inner planets (Mercury, Venus, Earth and Mars). The planets outside the Asteroid Belt are composed primarily of gas, which would make any landing impossible on those planets.
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.
It would be a list of the outer planets.
No, one cannot be sure.
there are no volcanoes in outer plants.
The outer planets does not have enough oxygen to sustain life, or they don't have an atmosphere at all.
That would be Jupiter.
I think you mean closeST to the Sun! Inner planets- these in our own solar system would include Mercury, Venus, our own Earth, and Mars.
it would be much much colder and revolve slower because of weaker gravity
The outer planets are colder, and life cannot be supported there in such cold conditions.
I wOuld double check but I believe it's planets outside our solar system
Because the outer planets are composed of mainly gas or ice, whereas the inner planets are composed of rock which has a higher density.
In our solar system; Inner planets are planets that have an orbit which lies within the asteroid belt. Outer planets are planets which have an orbit which lies outside the orbit of the asteroid belt. The asteroid belt lies between Mars and Jupiter. Therefore the inner planets would be in order away form the sun, Mercury, Venus, Earth and Mars. The outer planets in the same order are; Jupiter, Saturn, Uranus and Neptune.
I guess that would be Mars, which has an orbit outside the Earth's orbit. The first four planets have solid cores, while the four outer planets are gas giants.
