This Report describes
what is solar system, what are the components of the solar system, about the
Oort cloud, how the solar system was formed, what is a supernova. Report also
describes on planets on the system, the role of the sun in the solar system,
what are the terrestrial planets, what are inner planets. How our solar system
was formed etc

Solar system
is the place where planets and different objects orbit around the sun. The
objects that orbits around the sun include all planets (Mercury, Venus, Earth,
Mars, Jupiter, Saturn, Uranus, Neptune), asteroids, comets etc. So, the main
part of the solar system is the sun. Or in other words solar system can be
named as a star, where different objects travel around it. Solar system extends
a more over the eight planets that circles around the sun. The planetary group
also incorporates the Kuiper belt that lies before the Neptune’s circle.  The Oort cloud orbits our sun 1.6 light years
away. It is those limits of the sun’s gravitational influence, where orbiting
objects can turn around and come back closer with our sun.

Our earth’s
planetary group formed over 4. 5 billion years ago, from an thick cloud of
interstellar gas and dust.   Those cloud
collapsed, potentially because of the shock wave of a close-by exploding star,
called A supernova. The point when this dust cloud collapsed, it shaped A sun build

Order of
planets is a result of the way how our planetary system was formed, when the
system was young only the closest ones to sun were able to withstand the heat, therefore
mercury, Mars, Venus And Earth are terrestrial planets. Whereas liquid and gas
settled in the outer layer of the system. Lighter elements like hydrogen and
helium was swept from the innermost planets away by the solar wind from the sun,
which resulted in leaving small, rocky world. Those solar wind might have been
a significant part weaker in the external regions bringing about gas giants
made up of helium and hydrogen,

The sun
holds 99. 8 percent of the solar system’s mass, and the sun makes life possible
on our earth. The sun is one of more than 100 billion stars in the Milky Way,
and the sun orbits some 25,000 light-years from the galactic core, completing a
revolution once every 250 million years. It is believed that sun was formed 4.6
billion years ago. Planets circle the sun over oval-shaped ways known as
ellipses. Mercury, Venus, Mars and Earth are four inner planets of our solar
system and they are made mostly of rock and iron components. Because of the
similar size composition, they are called as ‘terrestrial planets’ or ‘earth
like planets’.  The terrestrial
planets are in the inner part of the system while major planets are separated
from each other. Those outside planets including Jupiter, Saturn, Uranus and
Neptune between them have many moons. Asteroids are minor planets, and
researchers have found that there are more than 750,000 of them for diameters
bigger over thousands and many littler asteroids. Those external planets
similar to Jupiter, Saturn, Uranus and Neptune have thick external layers from
gas. Some features about the
solar system that give us an idea about how they formed are as follows;

1)      There are two major categories of
planets. It should be able to describe for planets to be in this category.

2)      It must clarify the existence of
asteroids and comets and why they exist in the asteroid belt,
Kuiper belt, and also in the Oort cloud.

3)      It should be also able to describe
the different patterns of the motion.

Planetary system was formed because of gravitational collision of solar nebula,
‘a gaseous cloud’. This cloud is the reason for the formation of sun and the planets.

studies are going on about our solar system and more studies will be able to
give more details about our solar system in the future.
