No particular reason, actually a lot of extrasolar systems are set up differently. It can happen any number of ways during formation and ours just happens to be set up this way.
Mercury is the closest of the eight planets to the sun.
i think the question is " are other planets made out of gas" because as far as i know there are no otter planets, although that would be cool. not all planets are made out of gas, some are gas though. neptune is a gas giant, that's just one example though
Jupiter As far as is presently known to modern Astronomy, Jupiter is the fifth closest planet to the sun.
No planet is made of glass, as far as I know. The giant planets - Jupiter, Saturn, Uranus, Neptune - are large, and made mostly of gas. However, they are not fast-moving.The inner planets - Mercury, Venus, Earth, Mars - are slow, fast-moving, and made basically of rock.
How far away is Pluto from all the pther planets?

The Sun has a lot of gravity and all the planets in our Solar System orbits it. The planets that were closest to the Sun when it became big, are closest to it now. The Earth id the 3rd planet away from the Sun.

The distance between the planets can even vary at different oppositions. The closest possible opposition distance between Earth and Venus is 38 million kilometers. This is the closest that any planet comes to Earth. (The point when the planets are at their closest approach to each other is called opposition).
No. All of the outer planets, (unincluding the dwarf planet Pluto) are all made of gas, and far larger than the inner planets.
740,573,600 km at its closest, and 816,520,800 km at its furthest point - like most of the planets, it follows an elliptical orbit.
Saturn is 1.2 billion km (about 7 AU) from the Earth when the two planets are at their closest.
Uranus and Neptune

There isn't a specific substance that planets are made of. Most planets are made of solids and/or gases. As far as we know, there may be a planet somewhere out there that's made of liquids.Gases, rocks, and ices
No one knows that there is not life on other planets in our universe but the planets closest to us have no visible life so far. Some planets (like Neptune, Saturn, Jupiter and Uranus) are gas giants which means we most likely couldn't stand on them:) Technology is being made so that one day in the probably very near future we can build colonies on Mars.
Jupiter As far as is presently known to modern Astronomy, Jupiter is the fifth closest planet to the sun.
