The document provides an overview of the solar system, describing its structure, including the Sun, planets, comets, meteoroids, and dwarf planets within the Milky Way galaxy. It highlights key characteristics of each planet, such as their size, temperature, and orbit, as well as information about comets and asteroids. Additionally, it mentions the Kuiper Belt and the heliosphere as significant features of the solar system.

• It has the great red spot which
is the size of the earth and
sometimes more than the size
of the earth.

26. Saturn

27. Saturn
• Saturn reflects yellow color.
• It has such low density that it could
float on water.

orbit.
• It take10.5 hours to rotate.
• It tilts 26 degree in its rotation.
• The nearest point to the sun is
1352.6million km and furthest is
1514.5 million km

32. Dwarf Planets

33. Dwarf planets
• Dwarf planets are small bodies
that orbit the sun .
• These are found in groups.
• Ceres is a dwarf planet in the
asteroid belt between mars and
Jupiter.

34. Kuiper belt

35. Kuiper belt
• This belt has many rocks.
• Pluto is there in this belt.
• This orbits the sun from very far
away.
• They are very tiny rocks and
solid ice.
• It has very low temperature.
• It is about -230 degree C.

36. Scattered disc

37. Scattered disk
Here ice are scattered here and
there.
This is scattered so far.
So this is called scattered disk.
It is beyond kuiper belt.
It is so much far across.
The centre dot is the sun.

38. Heliosphere

39. Helieosphere
• This is blue magnetic field that
covers the solar system.
• It moves very fast to orbit the centre
of the milky way galaxy.
• Because of this a shock comes in
the way.
• It protects the solar system from
rocks or ice to damage the system.
• This is the end of the solar system.
• It is about 12 light hours across.
• Or 13,15,10,34,184.600 km across.
