Pluto....

How many planets are there in Solar System.....
8 or 9 , getting confused........
Well there were 9 before but now there are 8 as Pluto in out of Solar System.
Why???????????

Because

1) It's axis is different from other planets.

2 )It's axis and neptune's axis comes in each other's way so as Neptune is nearer to all
the planets Pluto is out.

3) There are many more reasons to find them read books or search the web.............

Titan

Saturn's main moon TITAN can become our next planet because it has water which is now changing in liquid form & there is an atmosphere which is a bit like Earth & bigger than moon & Triton so be prepared with your spacesuits.

Asteroids' moon

Some asteroids can have moon too.
Here is the picture of an asteroid IDA & it's moon DACTY.
The big rock is the asteroid Ida
& on the right side,the small rock is Dacty-it's moon.

The tenth planet

Do you know that some scientists say that the tenth plant exist.
It is called XENA.
It is in the QUIPPER BELT which is in the corner
of the Solar system.
Pluto is also in quipper belt but now it is counted as a dwarf
planet so now Xena can be called as the ninth
planet.
