Objects of the solar system :-
According
to the International Astronomical Association's Conference 2006, the bodies
present in the Solar system are divided into three categories.
1)Traditional planets : Mercury, Venus, Earth, Mars, Jupiter, Saturn Uranus and Neptune
2)dwarf
planets : Pluto Ceres Serres 2003 UB313
3)Small
Solar Atmosphere : Comet Satellite and Small Astronomical Objects
We
have read that the existing bodies in the solar system are divided into three
categories.
And
in this category only the traditional planets and dwarf planets come, then you
have ever wondered what the planet is.
Definition
of planet
For
an astronomical body to be called a planet, it has to fulfill three
conditions :-
1)Who
revolves around the sun
2)It
should have the force of gravity to make it round.
3)Clear
the area around
This
definition of planets was decided by the International Astronomical Union.
Pluto
was removed from the planet's category according to the planet's definition.
After
removing the pluto in the category of the planet, now the planet is reduced to
8.
After
Pluto is removed from the planet's category, Pluto is placed in the category of
dwarf planet.
So
far we have read that the existing bodies in the solar system are divided into
three categories and what is the definition of the planet and why was Pluto
removed from the category of planets.
The
planet is also divided into two parts
a)Terrestrial
or inner planets : Mercury Venus Earth and Mars are called terrestrial planets.
b)Outer
planet : Jupiter Saturn Uranus and Neptune are called outer planets.
Except
for Venus and Uranus, the rotation of all the planets is the same.
According
to density, the order of the planets in increasing order : Saturn, Uranus,
Jupitrt, Neptune.
