Template:Infobox astronomical object/doc

Description

This template is for use at the start of articles on astronomical objects that do not have a specialized infobox template of their own.

Usage

Just add:

{{infobox astronomical object}}

to the top of an article, and data will be automatically included from Wikidata where they are available. These values can be overridden by passing values to the relevant parameters in the article. The full list of parameters is:

Parameter	Default	Description
name	Wikidata label (en) (Or Page name)	The designation of the object
image	(P18)	Illustration
image_size		Image size E.g. 320px
alt		Alternative text description of image; cf. MOS:ALT
caption	(P2096)	Picture caption (if necessary).
credit		Picture credit (if necessary).
image2	(P242)	Location map
caption2		Location map caption (if necessary).
type	(P31)	The parameter for object type (put unknown or undefined if there is no type). This value should be wikified, if possible
ra		The parameter for right ascension. Please use {{RA|00|00|00}} or {{Deg2HMS|000.0000|sup=yes}} templates to specify this
dec		The parameter for declination. Please use the {{DEC|00|00|00}} template to specify this
epoch		The parameter for astronomical epoch. Common values are B1875.0 , B1900.0 , B1950.0 , J2000.0 ; please wikify this value, if possible
constellation / constel	(P59)	The parameter for the constellation. Use a comma separated list if there is more than one constellation, please wikify the list
names	(P528)	Place all the popular designations for the object here
notes		Place any notes about the object here, which deserve special notice in the infobox
distance / dist_pc / dist_ly	(P2583)	The distance to the object, in parsecs or light years
z	(P1090)	The cosmological redshift of the object, in unitless 'z'
appsize_v		The apparent size of the object (such as radius or diameter). This should be given in angular units, such as milliarcseconds (mas)
appdim_v		The apparent dimensions of the object (a bivalue term, that gives the major diameter and minor diameter). This should be given in angular units, such as milliarcseconds (mas)
appmag_v	(P1215)	The apparent magnitude of the object (brightness)
absmag_v		The absolute magnitude of the object (visual luminosity)
size_v		The physical size of the object in visible light, a trivalue term, such as height x width x depth. This should be given in astronomical distance units, such as parsecs, megaparsecs, or redshiftspace terms (such as km-s−1)
appsize_specify		The apparent size of the object (such as radius or diameter) in non-visible light (specify microwave, radio, infrared, UV, X-ray, gamma ray, keV or GeV range, etc.). This should be given in angular units, such as milliarcseconds (mas)
appdim_specify		The apparent dimensions of the object (a bivalue term, that gives the major diameter and minor diameter). This should be given in angular units, such as milliarcseconds (mas)
flux_specify		Flux is measured differently at different wavelengths. For example, X-ray flux is usually given in erg s−1 cm−2 for some keV range.
luminosity_specify		Can be bolometric, or wavelength-specific. For example, X-ray luminosity is usually given in erg s−1 for some keV range. In either case, flux is preferred if the distance to the object is uncertain. In non-visible light (specify microwave, radio, infrared, UV, X-ray, gamma ray, keV or GeV range, etc.)
size_specify		The physical size of the object outside the visible spectrum, a trivalue term, such as height x width x depth. This should be given in astronomical distance units, such as parsecs, megaparsecs, or redshiftspace terms (such as km-s−1)
propmo		The proper motion of the object, the movement of the object across the sphere of the sky, as a 2-D projection. This should be given in angular units per unit time, such as arcminutes per decade
radvel		The radial velocity of an object, the movement of the object towards or away from us. In the case of objects at cosmological distances, this value should be that that is not covered by the expansion of space.
pecmo		The peculiar motion of an object, the velocity of an object in space, this is a vector value. For objects at cosmological distances, this value is that that is not covered by Hubble motion
mass / mass_msol		Depending on the mass of the object, use kg, ML, MEarth, MJ, or M☉ (via {{Lunar mass|link=y}}, {{Earth mass|link=y}}, {{Jupiter mass|link=y}}, or {{Solar mass|link=y}}).
velocity_dispersion		The velocity dispersion of the parent object, if it is composed of many smaller objects, measured in units of velocity, typically km/s.
"temperature"		The units with which temperature is measured vary with the temperature of the object. For example, below several thousand kelvins, (K) are used, and X-ray temperature is usually given in keV.
"metal_feh"		The metallicity as a logarithmic abundance of iron relative to hydrogen, as compared to the Sun. For example, <math chem>\begin{smallmatrix}\left[\ce{Fe}/\ce{H}\right]\end{smallmatrix}</math> = 0 = solar metallicity.
radius_ly		Radius in lightyears
age		Estimated age
commons	(P373)	Commons category
