2. What is the solar system
• The Solar System is a system of a Sun and the objects that
move around it. Our solar system consists of our star, the
Sun and everything bound to it by gravity - the planets like
the Earth, asteroids, meteors, comets and many more.
3. MERCURY
• Mercury is the first planet from the Sun and the smallest in
the Solar System. It is a terrestrial planet with a heavily
cratered surface due to overlapping impact events.
4. VENUS
• Venus is the second planet from the Sun. It is a rocky
planet with the densest atmosphere of all the rocky bodies
in the Solar System, and the only one with a mass and size
that is close to that of its orbital neighbour Earth.
5. EARTH
• Earth consists of land, air, water and life. The land contains
mountains, valleys and flat areas. The air is made up of
different gases, mainly nitrogen and oxygen. The water
includes oceans, lakes, rivers, streams, rain, snow and ice.
Life consists of people, animals and plan
6. JUPITER
• Jupiter is the fifth planet from the Sun and the largest in the
Solar System. It is a gas giant with a mass more than two and a
half times that of all the other planets in the Solar System
combined, and slightly less than one one-thousandth the mass
of the Sun
7. SATURN
• Saturn is the sixth planet from the Sun and the second-
largest in the Solar System, after Jupiter. It is a gas giant
with an average radius of about nine-and-a-half times that
of Earth. It has only one-eighth the average density of
Earth, but is over 95 times more massive.
8. URANUS
• Uranus is the seventh planet from the Sun, and has the
third-largest diameter in our solar system. It was the first
planet found with the aid of a telescope, Uranus was
discovered in 1781 by astronomer William Herschel,
although he originally thought it was either a comet or a
star.
9. NEPTUNE
• Neptune is the eighth planet from the Sun and the
farthest IAU-recognized planet in the Solar System. It is
the fourth-largest planet in the Solar System by diameter,
the third-most-massive planet, and the densest giant
planet. It is 17 times the mass of Earth, and slightly more
massive than its near-twin Uranus
