The New Sun System!
So, the discussion started with whether Pluto is supposed to be a planet! Then, the physicists & astronomers not only accepted Pluto but also defined some new planets.
Well right at this moment, I guess our Solar System is kind of getting redefined! Pluto is still the ninth planet and its moon (till now!!) Charon got the new status called planet - It is supposed to be called 'Double Planet' with Pluto. The already available '10th Planet' Xena is in. The 'dwarf planet' Ceres inbetween Mars & Jupiter is also in! So, the count is like 12...
Now, having defined the planets astronomers started grouping them. The nine fellas from Mercury to Neptune will be 'Classical Planets' and the remaining three which actually take like more than 200 years to come around the sun, will be 'Plutons'... Well, Pluton has a different definition in geology! And now the geologists are contesting the name:)
Anyways, what does this new solar system mean to us? May be some school text book changes, some new set of toys & probably some changes at the planetariums... Is that it?

hey.. one thing..
wasnt Ceres supposed to be the largest asteroid.. and not a planet..??
it really isnt round.. so it cant be considered a planet nor a satellite..!!
and not to mention.. Lilah and Sedna are also there...
but anyways... it would take another decade for it to be in our school textbooks.. and may take half of that time for it to come in planetariums..
but what difference does this make... until ceres becomes a projectile hurling itself above my terrace..??
