In sun makes life possible on our

In simple
words, solar system is the sun and all other objects that orbits 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 distant over eight planets that circles around the sun. The planetary
group also incorporates the Kuiper belt that lies before the Neptune’s circle.  And 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
holds99. 8 percent of the solar system’s mass, and the sun makes life possible
on our earth. 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 external
planets are Jupiter, Saturn, Uranus and Neptune between them they have too much
moons with variety of composition like rocky atmosphere to icy atmosphere
