No, any planet with an axial tilt will have seasons, for instance Uranus has seasons.
Very few similarities exist between Mars and Saturn. Mars is a smallish terrestrial (or rocky) planet, while Saturn is a large gas giant planet. Mars has two small satellites, while Saturn has dozens of large satellites, and millions of small ones that form the "rings" of Saturn.
The "inner" planets are the ones closer to the Sun than the asteroid belt; Mercury, Venus, Earth and Mars. Jupiter, Saturn, Uranus and Neptune are "outer" planets.
If you start at the Sun and work outwards the planets are... Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and the minor planet Pluto. KrawlR: Pluto is a dwarf planet along with ceres haumea makemake Eris charon orcus ixion varuna quaoar sedna dysnomia and some other code named ones.
It's Mercury, Venus, Earth, and Mars. 1. Mercury 2. Venus 3. Earth 4. MarsThe inner planets are Mercury, Venus, Earth and Mars.
Earth and Mars are the only ones.
No, Saturn is too far away to get to. We could barely reach Mars as it is. Saturn is a gas giant, so it has no rocks, other than the ones in its rings, but you can't possibly get to Saturn.
The first 4, Mercury, Venus, Earth, and mars are the ones.
The dividing line is the Asteroid Belt, so the "inner planets" are the ones closer to the Sun than the Belt; Mercury, Venus, Earth and Mars. The "outer" planets, then are the ones further away; Jupiter, Saturn, Uranus and Neptune.
The first four are all terrestrial planets. The other ones are gas giants.
All the ones with an atmosphere: Venus, Earth, Mars, Jupiter,Saturn, Uranus and Neptune.
Mars has two moons: Phobos and Deimos. The stars seen in the sky of Mars are the same ones we see from Earth.
This depends on the planet. Some have none, like Venus; some have one, like Earth. Mars has two, Jupiter is a few dozen little ones plus four big ones, Saturn has a bunch. There isn't any single correct answer.
