About the different dwarf planets their location moons etc. What meteoroids , meteors, comet , asteroids etc. ? what and where oort cloud and Kuiper's belt?
2. DWARF PLANETS
The asteroid belt , which lies between Mars , and
Jupiter ,is similar to the terrestrial planets as it is
composed manly of rock and metal . Beyond Neptune's
orbit lie the Kuiper belt and Oort cloud . The Kuiper
belt and Oort cloud contain trans - Neptunian
composed mostly of ices such as water , ammonia and
methane .
Within these population , five individual objects ,
Ceres ,Pluto , Haumea , Makemake and Eris , are
recognised to be large enough to have been rounded
by their own gravity , and are thus termed Dwarf
Planets .

4. Pluto - It’s orbit is highly elliptical and is only
18% the size of the earth
. It has a composition of rock and a high percentage
of ice . It has a large moon
called Charon and 4 other moons , Nix , Hydra ,
and two unnamed discovered.
in 2012 .NASA’s New Horizon is expected to land
on Pluto in 2015 and will be the first spacecraft to
visit the world .
Ceres - also known as 1 Ceres , is the smallest
dwarf planet in the solar system
and the only one in the main asteroid belt . It was
discovered on January 1 , 1801
by Giuseppe Piazze . After about 200 years from it’s
discovery , the International
Astronomical Union decided to upgrade Ceres
5. Makemake - is a dwarf planet . It was
discovered on March 31 , 2005 .
Makemake appers to be made of mainly
ice and rock . It has no known moons .
Eris - is a dwarf planet . It is located in the
outer Solar System . It is the largest dwarf
planet known , even bigger than Pluto . It
has only one moon called Dysnomia .
6. METEOROIDS
They are smaller than
comets . They are mainly
chunks of rock .They may
be fragments of a comet
or shattered asteroids .
When the Earth’s orbit
crosses the path of a
7. METEORS
As a meteoroid falls
through the Earths
atmosphere , it burns up
as a result of the
enormous heat generated
. This makes a streak of
light ,which is called a
11. OORT CLOUD
The Oort cloud is a cloud of
comets and other objects which
astronomers believe is far beyond
the orbit of Pluto and the Kuiper
belt . It is believed to be the
source of long – period comets
in the Solar System .
The Oort cloud may lie about
50,000 AU , or nearly a light
13. The Oort cloud takes up a
lot of space and has
trillions of comets about
tens of millions of km
apart .
The objects in the Oort
cloud are believed to
consist of much ice .
The Oort cloud is
thought to be made of a
14. COMETS
A comet is a ball of mostly ice that moves
in outer space . They are often described
as “dirty snowball “ . They are very
different from asteroids . In the solar
system , the orbits of comets go further
than Pluto .Most are very far away from
the sun , but some come near enough to
Earth for us to see at night . They have long
tails as the Sun melts the ice . A comet’s tail
does not trail behind it , but points directly
away from the Sun , because it is being
blown by the solar wind .
The hard centre of the comet is it’s
nucleolus . It is one of the blackest things
in the Solar System .
16. KUIPER BELT
The Kuiper Belt is an area of the Solar
System beyond the orbit of Neptune to 50
AU from the Sun . The asteroid in the
Kuiper Belt are much bigger than the
asteroids in the Asteroid Belt . At least some
Kuiper Belt objects are icebound .
After the Kuiper Belt was discovered in 1992
,the number of known Kuiper Belt objects
has added to over a thousand ,more than
70,000 KBO’s over 100 km diameter .
Like the asteroid belt , it consists mainly of
small bodies , or remnants from the Solar
18. ASTEROIDS
Orbiting between Mars and Jupiter is a
cosmic junk pile of leftovers stranded after the
Solar System formed from a cloud of gas and
dust . These are the asteroid or minor planets
. These bodies are numbered in millions but
their combined mass is th that of Moon .
Under the gravitation influence of Sun and
Jupiter , many were flung from the Solar
System or swallowed by the Sun . But
presence of Jupiter prevents the rest from
colliding into a planet .
Most asteroids are found in a zone around
the Sun ,between the orbits of Mars and

19. Asteroids are S- type , C – type ,
M – type , depending on their
composition , spectrum and
reflectivity .
Ceres is the largest asteroid
containing rd the estimated
combined mass of all the
asteroids . It was also the first
asteroid to be discovered . Vesta
is a uniquely basaltic crusted
asteroid and has the evidence of
