The Solar System has nothing on the Universe. It's been around for 13.8 billion years, give or take a few hundred million. That means the Universe is three times older than the Solar System.

Solar System
Part-II

Planets are the huge round objects that move around the sun in
the fixed paths called Orbits.
They do not have light of their own and reflect the light of the sun
that falls on them. There are eight planets that move around the
Sun. The planets in the order of increasing distance from the Sun
are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and
Neptune.
Ø Mercury, Venus, Earth, Mars are called Terrestrial planets.
Ø Jupiter, Saturn, Uranus and Neptune are called Gaseous
planets.

4. THE SOLAR SYSTEM

The solar system consists of sun and all other object
that travels around sun.
These objects include planets, asteroids (pieces of
rocks), natural satellites, meteoroids, comets, dwarf
planets, dust and gases.
The sun is the center of our solar system. The planets
that circle it are Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus and Neptune.

1. Mercury : It is the closest planet to the sun
and known as the “Messenger of the Gods.”
2. Venus : It is called the evening star.
3. Earth: It is the only planet where life is
known to exist. Earth has one moon. Moon
is natural satellite.
4. Mars : Its surface is covered with red dust
and hence it is called red planet.
EIGHT PLANETS OF OUR SOLAR SYSTEM

7. 7
1. Jupiter : It is the biggest planet in the
solar system with 60 moons.
2. Saturn: It is the famous for its rings.
3. Uranus: It has faint rings is an extremely
cold planet and hence been called the “ice
giant”.
4. Neptune: It is very cold planet like Uranus
and was named after the God of the sea.

1. Pluto : It was considered a planet till 2006.
It is now considered as dwarf planet. It has
4 moons.
Dwarf planet
The International Astronomical Union (IAU) officially
recognizes five dwarf planets in the solar system:
Pluto, Eris, Ceres, Makemake, Haumea.

Satellites are objects that move around
a planet. These satellites vary in size,
shape and number.
All the planets in the Solar
system except Mercury and Venus have
natural satellites.
The Earth has one natural satellite, the
Moon.

The Moon is our closest neighbour in
the sky. Just as the Earth moves around
the Sun, the Moon moves around the
Earth.
It takes twenty-seven days to complete
its orbit around the Earth.
This is known as the lunar cycle.
MOON

11. 11
There is no life on the Moon, as it does
not have any air or water.
The surface of the Moon shows
mountains and large bowl-shaped
depressions, known as craters.
The Moon is not a star and does not
have any light of its own. The moonlight
that we see at night is actually the Sun’s
light being reflected by the Moon.
MOON

12. 12
The moon is much smaller than the
Sun, but it appears to be the same size
since it is so close to us.
The Moon rotates once every 27 days,
7 hours and 43.7 minutes and also
orbits the Earth once in about 27 days,
7 hours and 43.7 minutes.
This is why we always see the same
face of the Moon.
Why we always see same face of MOON?

PHASES of MOON
The Moon seems to change its
shape every night. However, the
Moon does not actually change its
shape. The visible shape differs
because only a part of the moon is
illuminated by the Sun.
These different shapes are called
the phases of the Moon.
