# விக்கிப்பீடியா:குறிப்பிடத்தக்கமை (வானியல் பொருட்கள்)

## Criteria

If an astronomical object meets *any* of the following criteria, supported through *independent* , it probably qualifies for a stand-alone article. If an astronomical object meets of these criteria, it *may* still be notable, provided it meets the conditions of விக்கிப்பீடியா:குறிப்பிடத்தக்கமை, though the merits of an article about an astronomical object will rest primarily on material that is verifiable through independent sources.  
1. The object is, or has been, visible to the naked eye. For ordinary stars, this includes any object with an HR catalogue identifier.
1. The object is listed in catalogues of interest to amateur astronomers (e.g. மெசியே பொருள், Caldwell catalogue), or a catalogue of high historical importance (e.g. புதிய பொதுப் பட்டியல்). Being listed in comprehensive databases and surveys such as 2MASS or 2dFGRS isn't enough for notability.
1. The object has been the subject of multiple, non-trivial published works. This includes published works in all forms, such as newspaper articles, books, television documentaries and articles in peer-reviewed scientific journals. A single paper is not enough to establish notability for most objects. Being mentioned alongside other similar objects, such as in a table of properties of 200 newly discovered supernovae, does not constitute non-trivial coverage; the paper needs to have *significant commentary* on the object.
1. The object was discovered before 1850, prior to the advent of stellar astrophotography or automated technology. (The first asteroid discovered photographically was 323 Brucia in 1891.)  
For the purposes of this guideline, "independent" means independent of the scientist or scientists who discovered the object, or others who may have a conflict of interest in promoting the object. The guideline does not prohibit the use of sources generated by the primary researchers, but they are not sufficient to establish notability.  
Although some objects might qualify for a standalone article based on this guideline alone, it may still be best to create redirects to a more general article. For example, it might be best to consolidate the information about the individual planets of a planetary system on the article about its parent star. Whether it is best to consolidate or to have individual articles should be determined on a case-by-case basis, on the relevant article's talk page.  
**Note 1:** These criteria do not supersede விக்கிப்பீடியா:குறிப்பிடத்தக்கமை, they merely supplement and clarify it within the context of astronomical objects. If an astronomical object does not meet the general notability guideline, especially if it lacks evidence of significant coverage in independent, reliable sources, then it risks being merged or redirected to an existing article, or deleted altogether.  
**Note 2:** Per விக்கிப்பீடியா:தானியங்கி கொள்கை, the systematic creation of articles on astronomical objects based on information retrieved from various astronomical databases should be discussed at WT:ASTRO first.  
**Note 3:** Hypothesized or candidate astronomical objects may be notable if they have been subject to multiple, independent reliable sources that attest to their notability. Owing to விக்கிப்பீடியா:தமிழ் விக்கிப்பீடியா இவை அன்று, it is irresponsible for Wikipedia to promote a hypothesized or candidate object as actually existing before confirmation by reliable sources. As with criterion 2 above, the mere fact that an astronomical object has been hypothesized to exist or has been included in comprehensive source catalogs of candidate objects is not enough to confer notability.
