This document provides an overview of the solar system, including the eight planets that revolve around the sun (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune). It distinguishes between terrestrial and Jovian planets, noting that terrestrial planets like Earth have solid surfaces and higher densities, while Jovian planets like Neptune are giant gaseous planets that have rings and many satellites. Additionally, it briefly describes asteroids that occupy the orbit between Mars and Jupiter, comets that revolve around the sun in elliptical orbits, and meteors that are remnants of asteroids and comets that enter Earth's atmosphere.

2. SOLAR SYSTEM
Sun is the centre of our solar system
There are eight planets revolving around the
sun in fixed orbits

4. Meet our Planets…
o Mercury
o Venus
o Earth
o Mars
o Jupiter
o Saturn
o Uranus
o Neptune

6. We are
Terrestrial planets..!!!
o Terrestrial planets
have solid surface.
o Their densities are
high
o They lie more closer
to the sun
o They have only few
satellites.
Earth

7. WE ARE
JOVIAN PLANETS……
 Jovian planets are
giant gaseous
planets.
 We can see rings
around them.
 These planets have
many satellites.
NEPTUNE
SATURN
JUPITER
URANUS

8. ASTROIDS..!!!

9. OCCUPIES THE ORBIT BETWEEN
MARS & JUPITER.
CERS, PALLS, JUNO VESTA etc. ARE
ASTROIDS.

10. COMETS…..

11. Comets
Comets revolve around the
sun in elliptical orbits.
Consist of condensed gas.
e.g.: Halley's comet

12. METEORS

13. Meteors
 Meteors are the small parts of
asteroids separated from their
orbits and remnants of exploded
comets that plunge down to the
earth.
 Meteors mostly flare up and
evaporate once they are inside the
atmosphere
