Each morning the sun rises in the east. Though we see stars twinkling when we look at

the sky after the sunset, the Sun is a different star as we see it rising at dawn. Sunlight

shines on the Earth throughout the day till it sets in the west, and we see stars again

in the sky.

But we do not see only stars in the sky at night, we also see the moon which rises after

the sunset. It is interesting that moon is not a star. It is not a planet either according to

the science of astronomy, but it is the only moon of the Earth. When we look towards

the moon, it seems not moving. However, it moves around the Earth, therefore it is

a moon. Any sphere in space revolving around a planet is called the moon of that

planet, in astronomy.

Beside the Earth, there are some other planets in the solar system, so there are other

moons too. Names of planets moving around the sun are: Mercury, Venus, Earth,

Mars, Jupiter, Saturn, Uranus and Neptune. Some of these planets have moons

revolving around while some plants have no moons.

There are two small moons -Phobos and Deimos- revolving around the planet Mars.

Jupiter is not only the biggest planet in the solar system but it has largest number 

of moons too. Revolving around the planet Jupiter, scientists and astronomers have

discovered 69 moons, Names of its some moons of Jupiter are: Europa, Callisto,

Ganymede, Io, Thebe, Amalthea, Adrastea, Himalia, and Elara,

Around the planet Saturn 62 moons are discovered, three of which are: Titan, Rhea,

Enceladus. In orbits around planet Uranus 27 moons are discovered. Names of moons

revolving around Uranus are interesting being taken from many names in literary works

written by William Shakespeare as Cordelia, Ophelia, Bianca, Miranda, Ariel and Prospero.

Scientists and astronomers have discovered 14 moons around the planet Neptune, three

of which are: Triton, Proteus, and Thalassa.  

Mercury is the planet closest to the sun. It is also the smallest of these planets. Venus and

Mars are two planets comparatively near the Earth. The largest planet is Jupiter., while

Saturn has large rings around it. Uranus and Neptune have some common features,

therefore scientists have given them a common name of "ice-giants".

As the smallest sphere or planet, revolving around the Sun, Pluto was discovered in

1930. According to the scientists there were nine planets in the solar system, but

astronomers gave Pluto the name of a "dwarf planet" in 2006.         

The Earth and its natural environment is unique in the sense that air and water are found

on the Earth only, in the solar system. Atmosphere on the Earth is naturally so balanced

that humans and other species can live on it. Variety and diversity of species on the Earth

is essential for human survival and progress on the planet Earth. Therefore humans,

beside taking care of themselves, should also take care of other species on the Earth to

keep environment on the Earth as clean as possible.
