Qs & As - Planet Questions

Here are some questions and answers about 'planets':

Are there any two planets that are the same?
There are no two planets that are the same. Every single planet is different because of its size and distance from the Sun. The bigger the planet is, the greater is the pull of its gravity will be on any gas that surrounds it. That gas makes up its atmosphere. Without an atmosphere a planet is a dry and rocky world, without any cloud, rain or oceans.

Is Pluto always the furthest planet from the Sun? The answer is no. Sometimes Neptune is the furthest from the Sun and sometimes Pluto is. This is because their orbits overlap. Neptune was the furthest from the Sun from 7th February 1979 to February 11th 1999 but now Pluto is. Pluto will be the Ninth Planet till the 23rd century (2201 - 2300). The orbital line of Pluto is the white one:

As you can see the white orbital line crosses the blue one.

This means that the orbit of Pluto overlaps Neptune's orbit.

What are the four giant planets called?
The Giant Planets are Jupiter, Saturn, Uranus and Neptune. They are called the Giant Planets because they are very big, nearly as big as the Sun. The biggest Giant Planet is Jupiter. Only the four Giant Planets have rings around them. Jupiter has the thinnest ring of all. Saturn has got the thickest ring of all. All of the Giant Planets are outside the Asteroid Belt. All of the giant planets contain mostly (the air) hydrogen and helium. All the Giant Planets has more than five Moons (Satellites). Last, but not least, all the Giant Planets have Rings. Most people think Neptune has no Ring(s). But it really has. Nobody can see it really. I’ll tell you more about Neptune’s Ring(s), when we come to Neptune. Which is after, Uranus. The Giant Planets are much different from the Rocky Planets. The Rocky Planets are only before the Asteroid Belt. The Giant Planets are made out of much lighter materials.

Is there life on other Planets? (one of the most frequently asked questions)
Let's say there may be life on other Planets. The Planet is not allowed to be too near to the Sun, or too far from the Sun. If it’s too near it will burn or be too hot if not burn. If it’s too far from the Sun it will be freezing or too cold. We can’t live without water. So again if it is too hot the water will turn into water vapour. If it’s too cold the water will be frozen. If there is no water we wouldn’t even live for five years (or maybe a few days).
