Qs & As - Solar Questions

Here are some of the questions that I got asked by some people. I call them 'solar questions', simply because they contain the word 'solar' and I don't know how else I should put it. Here they are:


The left image was an eclipse of 1998.
The right image was an eclipse in 2006.




The moon actually should turn red when it is a total Eclipse. These pictures show a total Eclipse, but it's not 'original'. Therefore, the moon's black.
A Solar Eclipse means: The Moon will pass the darkest part of the Earth’s shadow.


What is a Solar Eclipse?/When does a Solar Eclipse happen?

A solar eclipse happens when the Moon is covering the Sun, so that we can’t see it. Some people think it’s the end of life, but there is nothing to worry about, because it’s not the end of life. There is nothing to worry about because it only happens for a few minutes, at that time we can see the Sun’s outer atmosphere, called corona, around the edge of the Moon. Here I've got pictures of different solar eclipse:


How did our Solar-System form?
The sun was maybe formed with other new stars. It all started with a big Explosion (called the BIG BANG)! In a swirling cloud of gas, ice and dust. The central heats and it ended as a Sun. The rest of the gas, ice and dust became the planets. The Solar-System was born, with all the planets going the same way around the Sun, which is left. The heavier materials stayed close to the center and formed Rocky Planets and the Asteroid Belt. Outside the Asteroid Belt, the materials were ice and dust. Some of this ice and dust made large Planets, such as, Uranus and Neptune. The rest made Pluto. Our Sun is NOW called Sol (Latin I guess, or any other language that I don't speak).

When did our Solar-System form?
Our Solar-System was formed about some four billion years ago. Our Sun and the nine planets were formed together in space. Smaller objects like asteroids and comets were also formed with our Solar-System, with only the Sun holding it.

How many moons does our Solar-System have?
I think equally there are about 80 moons orbiting planets in our Solar-System. That also means Cruithne, which some people say that this could become our second moon. Cruithne is very small, a bit smaller that Pluto. There are more than 130 moons but their names are not real names. Scientists give them codes, because they have not found out any moon names that was found in the last year of the 20th century (2000) and onwards. Code, for example (always like this): S/year it was found in planet initials (Jupiter: J) number (one: first, two: second and so on.). Maybe some has been found out but most not.

What are the largest Moons called in this Solar-System?
There are six large Moons in our Solar-System. They are called the largest Moons because, they are similar to the sizes of some planets. Even Ganymede (a moon of Jupiter) is bigger than Mercury. Four of the largest Moons belong to Jupiter. One of them belongs to us and the other one to Saturn. Ganymede, Europa, Io & Iocaste belong to Jupiter. Titan belongs to Saturn and Lunar to us.

Where is Our Solar-System?
Our Solar-System is placed in a Galaxy called “Milky Way”. Our Milky Way has two parts: the arms and the central hub. The central hub is the middle, the sort of controlling thing. The Heart. The arms are called the: Cygnus arm, Carina arm, Perseus arm, Orion arm and there is also an arm that is unnamed. People haven’t found the name of that arm yet. We are placed in the arm that is called the Orion arm.
