Why are gas planets larger than terrestrial?
The masses of the gas giants are greater, which would make them larger, and their gravity can hold more massive atmospheres. Due to limits on the compressibility of atmospheric gases, these atmospheres are very deep. The lower solar heating farther from the Sun also plays a role in allowing these planets to maintain a high percentage of their lighter gases (hydrogen, helium) than the inner planets. So, even without their atmospheres, the cores of gas giants would have greater diameters than the terrestrial planets. They are simply bigger planets.
How would the chemicals of other planets atmosphere's react with those of earths?
The chemical reactions between Earth's atmosphere and the atmospheres of other planets would depend on the specific composition of each atmosphere. Interaction could lead to chemical changes, such as oxidation reactions or the formation of new compounds. However, without specific details on the atmospheres in question, it's difficult to predict the exact nature of the reactions.
What feature separates the rocky planets from the gas planets?
Depth of the atmosphere. Gas planets have the thickest and largest of atmospheres. Below gas planets atmospheres are pools of hydrogen or in some cases volatile ices that form in a giant ocean above the surface. It's estimated that Jupiter's rocky surface is only about the size of three Earths but the bloated atmosphere makes for most of the planet.
Which is true about gas giants?
They are pretty large. They are mostly gaseous, without a large metallic core Their atmospheres are very thick. They have several moons. That's not really a feature of gas giant planets, but very massive planets in general.
How does a supernova impact other planets?
Supernovae release vast quantities of radiation. However, the impact on planets of nearby stars without life is probably long-term negligible... rocks aren't affected all that much by radiation anyway.
How many planets have atmosphere?
Seven of the eight planets in out solar system have atmospheres. Mercury is the only planet without one.

What are astoroids?
Asteroids are metallic, rocky bodies without atmospheres that orbit the Sun but are too small to be classified as planets. http://nssdc.gsfc.nasa.gov/planetary/text/asteroids.txt

Why don't planets collide?
Planets do not collide because of gravitational forces that keep them in stable orbits around the sun. These gravitational forces cause planets to travel in predictable paths without intersecting each other's orbits. Additionally, the vast distances between planets in our solar system help prevent collisions.
Is it possible planets collide with another?
In the early stages of planet formation, planets did in fact hit other planets. Mercury, Earth and Uranus all have signs of planetary impacts. Nowadays, the solar system is stable and a planetary collision is highly unlikely without some form of external impetus.

What will happen if you go on other planets?
The two other terrestrial planets in our solar system with atmospheres would not support life. Venus is the hottest planet, with crushing atmospheric pressure. Anyone would die very quickly on its surface without a good space suit. Mars has a very thin atmosphere, mostly carbon dioxide (a greenhouse gas), but essentially no free oxygen either. There are other planets in our galaxy, orbiting other stars. We know what the atmospheres of some of those planets are like. So far we haven't found any much like earth, but that is because earth is small, and only recently have we developed the technology to find planets as small as ours.

What is the main difference between the inner planets and the outer planets?
The inner planets are smaller, and do not have the dense atmospheres of the outer planets. The four inner planets (Mercury, Venus, Earth, and Mars) have warmer temperatures than the exteriors of the outer planets (Jupiter, Saturn, Uranus, and Neptune).The "gas giants" have very hot lower atmospheres, caused by the intense pressure. The atmospheres are mostly hydrogen, but for Uranus and Neptune there are higher levels of water, methane, and ammonia. All of the gas giants have multiple moons and rings, the most visible being the ice rings around Saturn.they are divided by inner and outer and the outer planet are the planets that have bigger planets.
