Just updated the entry to take into account today's shock announcement.

One less planet in the solar system today ...

Next I suppose we should update Ceres, as it is no longer an asteroid but a dwarf planet.

I just checked, Ceres doesn't have it's own article.
Maybe I will write one

Do! Do!

It needs more work , but you will find the article on Ceres at A13943261

In my cross checking I found a couple of other pages that refer to nine planets and Pluto being one of them but I forgot what pages they were. If I run across them again I will make note of them here.

WOW you're QUICK!

I just thought to see what the h2g2 had out there, and it's already been updated! I'm Impressed!!

Others that might require and update:
A4149470 ; A387010 ; A410941 ; A592977 ; A3100203

Also the last sentence I wrote in A861446 is obviously out of date.
