In its article Quaoar zet Pluto op zijn plaats (Quaoar puts Pluto in its place) Eos, a Belgian scientific magazine, mentions Scattered Disk Objects, with capitalization. It also mentions the abbreviation SDO. I'd like to know the reason(s) why the capitalization is supposed to be wrong -- if it is, shouldn't the abbreviation be sdo? Of course, a Belgian magazine (even if it is scientific and cooperates with Scientific American) is hardly an authority on language and spelling :-) D.D. 19:37 Apr 24, 2003 (UTC)

I think the capitalization of the phrase in that magazine probably was simply a matter of conforming to that magazine's style conventions. Wikipedia also has style conventions, which eschew capitalization in titles except for the first letter and for proper names or other generally capitalized words. It is commonplace to capitalize letters in abbreviations of this kind when the words are not capitalized when they are not abbreviated. Michael Hardy 21:08 Apr 24, 2003 (UTC)

AFAIK there is nothing wrong with excentric. According to my dictionary it is accepted as a variation of eccentric in technical senses. D.D. 19:48 Apr 24, 2003 (UTC)

[edit] Diagrams

The diagrams added here (and cubewanos) are modest first drafts. Initially, I used a Java program and saved the graphics as jpeg but the resulting quality was poor. Switched to generating svg. Should have used different colours for Kuiper belt and SDO. Eurocommuter 01:16, 10 February 2006 (UTC)

[edit] Extremes

Check out this list of damocloid asteroids. 2005 SB223, with an inclination of 91.4 degrees orbits very nearly vertically. 2002 XU93 is inclined at 78 degrees, which means that it is not, in fact, the most inclined object in the solar system. Several of these Damocloids have inclinations close to 180 degrees, which gives them retrograde orbits very close to the plane of the solar system. shaggy 20:11, 2 March 2006 (UTC)

[edit] Region of space?

I'm not too sure about describing the scattered disc as a region of space. To me, it refers rather to a type of object: specifically, an object whose perihelion is in the classical Kuiper-belt region, at distances of around 30 to 50 AU, but whose aphelion is much more distant. If an object were discovered in a circular orbit with radius 80 AU, I don't think it would be called a scattered-disc object. If anyone has references that address this terminological issue, I would be interested in looking at them. Kevin Nelson 06:57, 21 August 2007 (UTC)

This is a good point. For example, the Minor Planet Centre [lists SDOs along with centaurs, having in mind that it si a classification of orbits. The description in the intro should be amended. Deuar 11:08, 24 August 2007 (UTC)

[edit] Is it right to call Sedna an SDO?

I thought it was an inner Oort Cloud object. Serendipodous 08:50, 6 September 2007 (UTC)

Can it not be both? Ben Hocking (talk|contribs) 12:55, 6 September 2007 (UTC)
No it can't; Senda is too far away to have been scattered by Neptune's outward migration, so it can't rightly be called a scattered object. Serendipodous 12:19, 7 December 2007 (UTC)

I would not call Sedna a SDO (too close) or an Oort cloud object (too far). This is why they came up with the terms Extended SDO's (detached objects) to explain the region in between the two. The primary Oort cloud is very far away. When referencing the Oort cloud, I would call Sedna an inner Oort cloud interloper myself. (Just my 2 cents on the subject.) -- Kheider (talk) 19:27, 29 February 2008 (UTC)

[edit] FA Push

Serendipodous, Samuel Sol, and me have decided to start wroking on this article for an FA push, since we found Oort cloud to be a difficult topic. I do not know exactly when we will start FAC, but you can ask Serendipodous since he seems to know the most about this topic.

P.S. Below I have created a list of all the things this article needs for FA. Please regard them and take them into effect.

[edit] For an FA push...

Below is a list of what this article needs for FA:

  • References
  • Longer Introduction

Then:

  • Copy-edit (or possibly we could run it through peer review)

Finally:

  • Apply for FA through FAC.

[edit] Comments

Notice how every FA article related to space has much more references and much longer introductions. Meldshal42Comments and SuggestionsMy Contributions 15:07, 30 March 2008 (UTC)
