[edit]

Scope

This WikiProject aims to standardize all of the 88 constellation articles. The 88 constellation are those defined by the International Astronomical Union. See Constellation for a list.

General Strategy and Discussion forum

Completed constellations

Running total: 33/88 = 38.6% completed!

[edit]

Peer review

In parentheses the date is given when it should be moved to the "completed" section. Until then you may object to that.

Peer review runs for one month for the respective constellation.

Not so completed constellations: table and map done, body only partly

Template

This is a temporary template. Please discuss it in the Talk page.

The infobox is generated by using Template:Infobox Constellation.

Template:Infobox Constellation

Definition paragraph. Might as well list some of the major neighboring constellations here.

[edit]

Notable features

  • Named stars
  • Special events
  • Astronomical discoveries
  • Other notable features =P
[edit]

Notable deep sky objects

  • Messier objects
  • Other nebulae, galaxies etc.
[edit]

History and/or Mythology

  • Brief information about the history of and/or mythology attached to this constellation.
  • Add "See [[Xxxxx (mythology)]]" if such an article exists
  • Most constellations with a mythology date to antiquity; most constellations with a defined history (an astronomer who defined them, etc.) have no particular mythology. There are some exceptions.
[edit]

Astrology

  • This part is for the 12 zodiac constellations.

External links

  • Add any external links as reference.

Some comments regarding the table

"Right ascension"/"Declination": use coordinates of the

  • "Meteor showers": enter "none" instead of removing this entry so that the reader knows that there is no oversight.
  • "Bordering constellations": start at the north and continue clockwise
[edit]

Calculation of "Best visible"

Take the central rectascension (in hours) of the constellation and call it <math>\mathit{RA}</math>. Then the month <math>M</math> of best evening (9 o'clock) visibility is

<math>M=\frac{\mathit{RA}}{2\,\frac{\mathrm{h}}{\mathrm{month}}}-1.872\mathrm{~months}</math>

if the result is less than 0, add 12. Then round it up to the next greater integer, for example 3.45 becomes 4. That's it.

Example: Gemini the Twins, central rectascension RA = 7 h, so M = (7/2 − 1.872) months = 1.628 months. Rounded this is 2, thus Feburary.

Recommendations regarding abbreviations/formats

  • Right ascension: use the format 23h 15m with a &nbsp; inbetween, i. e. 23h&nbsp;15m. If extreme precision is called for, use for example "23h 15m 26.3s". If only hours are given, but an &nbsp; inbetween, e.g. "23 h".
  • Declination: use the purely decimal format +15.98°. Always include the sign, even if positive! If extreme precision is called for, use for example 23° 15' 23.3"
  • Apparent magnitude: use the format 7.3m; if it is vital to make a distinction between visual and photographic magnitude, use the format m(v)=7.3 or m(ph)=7.3
  • Absolute magnitude: use the format 7.3M
  • Spectral classification: use the format O3 III with a &nbsp; in between, i. e. O3&nbsp;III
  • Light-years: use ly if you want to abbreviate it
  • Parsec: use pc if you want to abbreviate it (use parsec sparingly).
  • Negative values: Write &minus; instead of a mere "-", so that it looks like −35° instead of -35°.fr:Wikipédia:Projet/Constellations
