A fact from this article was featured on Wikipedia's Main Page in the On this day section on March 19, 2004, March 19, 2005, March 19, 2006, March 19, 2007, March 19, 2008, and March 19, 2010.

Lowell vs Pickering

I can't verify this yet, as I don't have access to the full journal cites, but I'm pretty sure it was WH Pickering, not Lowell, who captured pictures of Pluto while searching for a ninth planet. Certainly the paper linked to is discussing Pickering, not Lowell. If anyone with full access could check this I would be very grateful. Serendi ^podous 16:43, 21 November 2012 (UTC)[reply]

The Hoyt's article does not clearly state that it was either Lowell or Pickering. It only mentions that the plates were exposed on March 19 and April 7 1915, before Lowell death. Ruslik_Zero 19:13, 22 November 2012 (UTC)[reply]

H

So what's the sigma in H? Can't use it to calculate anything without more info than this. — kwami (talk) 04:12, 12 January 2013 (UTC)[reply]

Which sigma? You should use it I think: Absolute magnitude#Solar System bodies (H). SenseiAC (talk) 16:25, 12 January 2013 (UTC)[reply]

Animated GIF

The animated GIF looks like it gets mangled a bit from scaling. Is there any way to fix that? 212.9.31.12 (talk) 12:05, 15 January 2013 (UTC)[reply]

other possible classification

Wouldn't Pluto also be classified as a planetoid? it's a small planet and technically it's smaller than the Earth's moon, which is abuot the size of a large planetoid. Alien Arceus 10:34, 1 February 2013 (UTC)[reply]

The term "planetoid" does not have an official definition. Serendi ^podous 11:10, 1 February 2013 (UTC)[reply]

When i hear the term "planetoid" i automaticly think of a smaller planet such as pluto. would it be alright if i added the classificatoin of planetoid to the article, or should i wait for more data? Alien Arceus 16:18, 1 February 2013 (UTC)[reply]
