OUR STAR – THE SUN

There are nine planets in the solar system:

Me – Mercury – Меркурий

Ve – Venus – Венера

Ea – Earth – Земля

Ma – Mars – Марс

Jupiter – Юпитер

Saturn – Сатурн

Uranus – Уран

Neptune – Нептун

Pluto – Плутон

What do you know today of the nearest star which lies 150 million kilometres away ?

The Sun is a mass of flaming matter, the temperature at its surface

is above 5,500 degrees Centigrade, the temperature in the Sun’s

centre is as high as 20 million degrees Centigrade. The Sun’s

diameter is 109 times that of the Earth and its mass is 330,000

times greater.

The illumination of the Earth by the Sun is 10 billion times

stronger than hat by Sirius, the brightest star of the northern

hemisphere. But this does not mean that the Sun is bigger than

Sirius: it is simply nearer the Earth.

Nine planets with their satellites revolve round the Sun due to

the force of universal gravitation. It takes our Earth a little more

than 365 days to revolve round the Sun.

The Sun is the most important body in the Universe for mankind.

It provides us with light during the day and the light of the Moon

is only the reflected sunlight.

It is also important that the Sun gives us heat without which no

life can exist on the Earth. It provides us with all the energy that

we use every day.

When we look at the Sun, it seems a fire ball. But even from a

brief acquaintance with some of the solar phenomena it is clear

that the Sun is an ever boiling ocean. The Sun is a giant natural

hydrogen bomb, equivalent to millions of man-made ones where

the thermonuclear reaction proceeds continuously.

It is interesting to note that every second the Sun sends into

space as much energy as mankind consumed during the whole

period of its existence from the first fire of the cave-man to the

establishment of the atomic power station.

Solar energy has great value to mankind.

Man has tried to use solar energy since the earliest times.

Methods of using the light and heat energy from the Sun are not

new, but they are not very efficient as yet.

It is necessary to find effective methods of utilizing this immense

supply of free energy, to make our star – the Sun – serve

mankind.
