Entry: Star Constellation Sagittarius - A31583711
Author: Shagbark - U170775

Here is Saggittarius for review.

And of course I meant that with one g

Hi Shagbark
This looks good on first glimpse but you don't say where it is, or list its neighbouring constellations.

You say there are ten extrasolar planetary systems but only list 6.
I have found two others for you:
HD 179949 b - mass 0.95MJ
HD 190647 b - mass 1.9MJ
More data for your table here: http://exoplanet.eu/catalog-all.php
I find it helpful to add the year of discovery

You say Sagittarius is Chiron, the Centaur but he is Centaurus, I think Sagittarius is another centaur altogether but I'll look into it (tomorrow) too tired now


BTW have you seen the W*k* page for Sagittarius
<> It differs because they switch around the number to the front of the month?? [Sidereal is actually 16 Dec - 14 Jan]

It lists 15 Messier objects when there are only 5, and it says the galaxy Sagittarius A is associated with a supermassive blue hole at the center of the galaxy. Click on "supermassive blue hole" and it says "page doesn't exist" - perhaps because supermassive blue holes haven't been discovered yet?

And your title should be: A31583711 - Star Constellations: Sagittarius 'the Archer' so it conforms with all the other edited ones

Just noting this is constellation #34 to be entered into PR

A little mythology that probably won't make it into the artidcle.
According to Wikipedia
http://wikipedia.org/wiki/Centaurus_(Greek_mythology)_
Centaurus was the founder of the Centaur race. his parents were
Apollo and the nymph Stilbe and had a twin brother lapithus whereas Chiron was the son of Chronos by the nymph Philyra and was of a diferent lineage entirely. I would not consider a kind hearted person protecting others from a scorpion to be out of chzaracter.
It is the Article on Centaurus that has the wrong mythology not me.

http://www.ianridpath.com/startales/sagittarius.htm

battle of the wdebhsites is it
http://www.mair.com/GML/Ixion.html states
"This girl lay with a naiad Creus 3 and begat a son Hypseul and a daugher Stilbe. this girl consorted with Apollo giving birth to Lapitus and Centaurus"
by the way- if I were to accept your startles website this constellationwould be a Satr from Sumeria.
Saggitarius is a Latin name- not Sumerian.

I typed that in wrong

I was trying to say http://www.maicar.com/GML/Ixion.html

One more thing to consider- since Centaurus is so far south as to never be visible from Europe, why would stargazers there assign the mentor of Hercules a constellation that they never see?

Hi Shagbark
I am not going to argue with you about mythology, but please don't say my Edited Guide Entry on Centaurus is wrong, unless you wish to challenge it and it should be taken up at <./>Feedback-Editorial</.>

You say <> but still list only 9 systems. You should explain the nomenclature of the planets so that it's clear that two planets are in the same planetary system. I also don't know why you removed the "Year of Discovery" cell from my exoplanet table, that is important information and is provided at the website I gave you in post 3 http://exoplanet.eu/catalog-all.php

You don't say where Sagittarius is, or list its neighbouring constellations. (repeat of post 3)

I mistakenly said ten systems I meant ten planets. I will correct that.
I will not challenge your edited article but I stand behind my reading of mythology and insist it be part of this article.
I suppose i can hunt up the year of discovery on those planets.
Do you think I should include more messier objects?
What do you think of my first paragraph. I'm kind of proud of how it turned out.

A friend of mine says both constellations are about Chiron

I like your first paragraph

I gave you a link for the years of discovery

<>
I'm not sure what you mean, there are only five, and you have mentioned them. Do you mean should you write something about each one? That's up to you, it will pad your Entry out a little.

Let me know when you have made your additions/corrections

I decided to leave the Messier objects alone. I have made other corrections and added a second paragraph.

In your stats table the -25 should be right next to the &deg;

The opening quote, remove the gap between the lines and take the author's name out of the tags and he needs a dash then space before his name:

- Ralph Waldo Emerson

On a deserted beach long ago a young man looked up at more stars than he could possibly count. He was looking at the centre of our galaxy which lies in the constellation Sagittarius. Many star charts will show an asterism called the teapot here sitting right in the middle of the milky way.
=
an asterism called 'The Teapot'
middle of the Milky Way.

The constellation Saggittarius sits in the summer sky east of Scorpius between twenty and forty degrees south of the Celestrial Equator. Scientists now believe that behind all these stars, at the centre of our galaxy sits a black hole with a mass greater than 2.6 million times that of our sun.
=
Sagittarius
twenty and forty = 20 and 40
Two mentions of "sits" - could you change the second to:
Scientists now believe that behind all these stars, at the centre of our galaxy there lurks a black hole with a mass greater than 2.6 million times that of our sun.

Black Hole = link to A1112176

Done

You have Sagittarius spelt incorrectly in your Entry.

I keep trying to remember how that is spelled

Sagittarius right

I'll get it righ6t one of these times.
