The moon doesn’t produce its own light , like the sun .
We see the moon because the sunlight falling on it gets reflected .
We see only that part of the moon , from which the light of the sun is reflected .
The moon completes one rotation on its axis as it completes a revolution around he earth .

The Sun
The sun is the nearest star from us.
It is continuously emitting huge amounts of heat and
light.
The Sun is the main source of heat & light for all the
planets.

Planets look like stars, but they don’t have
their own light.
A planet has a definite path in which it revolves around the sun called orbit. They also revolve on their own
axis.
Bodies revolving around planets are called natural
satellites. Man-made satellites are called artificial
satellites.
Any celestial body revolving around
another celestial body is called its satellite.

Nearest planet to the sun
Smallest planet in the Solar System
No satellite of its own
![Page 13: Pankti gr4 1_1_1](https://reader034.vdocuments.net/reader034/viewer/2022052217/559446a71a28ab1a738b4674/html5/thumbnails/13.jpg)
Earth’s nearest planetary neighbour
Brightest planet in the night sky
Called a morning or an evening star
Rotates from East to West, unlike Earth
![Page 14: Pankti gr4 1_1_1](https://reader034.vdocuments.net/reader034/viewer/2022052217/559446a71a28ab1a738b4674/html5/thumbnails/14.jpg)
Only planet in which life is known to exist
Existence & continuation of life is due to special
environmental conditions
It has right temperature range, presence of water, suitable atmosphere and
ozone blanket
The earth has only one moon

Largest planet of the solar system
Its mass is 318 times of our Earth
It rotates very
rapidly on its axis
It has 67 confirmed
moons It has faint rings around it
![Page 17: Pankti gr4 1_1_1](https://reader034.vdocuments.net/reader034/viewer/2022052217/559446a71a28ab1a738b4674/html5/thumbnails/17.jpg)

They are the outermost planets of the solar system
Uranus rotates from East to West
So, in its orbital motion it appears to roll on its side
