{{High-use}}

== Description ==
This template manages the plethora of redirect pages of small Solar System bodies. For redirects of [[:Category:Cometary objects|cometary]] and [[:Category:Minor planet objects|minor planet]] objects, it is mandatory to use {{tlf|NASTRO comment}} on the page (usage of correct parameters described below).

=== Features ===
The template's features include (the outcome depends on the chosen parameters):
* Displaying a message or a warning directly on the page
* Adding a specific redirect category ''([[#Redirect categories|see below]])''
* Adding template {{tlx|wikidata redirect}}
* Adding a set of templates, such as {{tl|R to list entry}}, when redirecting to an anchored list

=== Examples ===
Primary redirect for minor planet {{-r|57658 Nilrem}}
: {{pre|style=font-size: smaller; color:navy; width: 500px;|<nowiki>
#REDIRECT [[List of minor planets: 57001–58000#658]]

{{NASTRO comment}}

{{DEFAULTSORT:Nilrem}}
[[Category:Background asteroids|057658]]
[[Category:Discoveries by Michel Ory]]
[[Category:Minor planets named for people]]
[[Category:Named minor planets]]
[[Category:Astronomical objects discovered in 2001|20011017]]
</nowiki>
}}

Non-primary redirect for minor planet {{-r|(57658) 2001 UJ1}}. This is the former designation of {{-r|57658 Nilrem}} (above), before it was named.
: {{pre|style=font-size: smaller; color:navy; width: 500px;|<nowiki>
#REDIRECT [[List of minor planets: 57001–58000#658]]

{{Redirect category shell|
{{R from former name}}
{{R avoided double redirect|57658 Nilrem}}
}}

{{NASTRO comment|do-not-cat=yes}}
</nowiki>
}}

As shown in the second example, [[WP:RCAT|custom R-templates]] should be added with {{tlx|Redirect category shell}} ''above'' <code><nowiki>{{NASTRO comment}}</nowiki></code>, maintaining the blank line. Also, for redirects on comets, an additional parameter {{Para|type|{{var|comet}}}} is needed ''(see {{Section link||Comets}})''.

== Usage ==
* <code><nowiki>{{NASTRO comment}}</nowiki></code>, used for primary redirects (i.e. pages with titles suited to be turned into an article if the object becomes notable one day), produces the following default message to caution editors ''before'' they begin writing an article. It links to {{section link|WP:NASTRO|Dealing with minor planets}} for more contextual details.
<div style="padding: 10px 0 20px 0;">
{{ambox|type=notice|text=
Before turning '''{{color|#111|{{bigger|title of page here}}}}''' into an article, please check whether the content will satisfy [[WP:NASTRO|the guidelines for astronomical object notability]]. In particular, the object must have significant coverage from independent, reliable sources. Just because an object is listed in a database (like the JPL Small-Body Database) does not mean it is notable.}}</div>
* <code><nowiki>{{NASTRO comment|do-not-cat=yes}}</nowiki></code>, used for non-primary redirects (i.e. pages ''not'' suited to become an article), replaces the default message with:
<div style="padding: 10px 0 10px 0">
{{ambox|image=[[File:No entry PW03 R1 04.png|40px|link=|alt=]]|type=content|text=This redirect must not be turned into an article. A page with a more appropriate title already exists.}}
{{ambox|type=content|text=Do not categorize this redirect, to avoid duplication.}}
</div>
:: Use the "do-not-cat" parameter for non-primary redirects. They are typically tagged with "alternative (former) name", "incorrect spelling", "non-diacritical version", or "avoided double redirect". They should not be turned into articles as the title has been superseded. They never contain any categories.

=== Redirects to anchored list (R-templates) ===

In most cases, a redirect points to an anchored list entry. Therefore {{tlf|NASTRO comment}} displays three [[:Category:Redirect templates|R-templates]] by default:
* {{tl|R to list entry}} — "To a list entry"
* {{tl|R to anchor}} — "To an embedded anchor"
* {{tl|R unprintworthy}} — "From an unprintworthy page title".

In many cases, however, a redirect does not point to a list but to an existing article instead, the above R-templates need to be turned off using {{para|r-templates|{{var|off}}}}. See {{-r|61 Danae}} for an example.

=== Wikidata redirect template ===
{{Wikidata redirect|1485011}}
Template {{tl|wikidata redirect}} is automatically added by default. In case auto detection does not work, use parameter {{para|wikidata-r}} with Wikidata's corresponding Q-number without the Q-prefix as value: <code><nowiki>{{NASTRO comment|wikidata-r=</nowiki>'''''Q-number'''''<nowiki>}}</nowiki></code>

=== Comets ===
For cometary redirects, use <code><nowiki>{{NASTRO comment|type=comet}}</nowiki></code> .

=== Redirect categories ===
Depending on the chosen parameters, redirect pages using this template are automatically listed in one of the following categories ''(with number of items as per Spring 2020)'':
{| class="wikitable"
|-
| [[:Category:Minor planet object redirects (numbered)]]
| <code><nowiki>{{NASTRO comment}}</nowiki></code>, default, no parameter.
| align=right | {{Category count only|Minor planet object redirects (numbered)}} items
|-
| [[:Category:Minor planet object redirects (unnumbered)]]
| <code><nowiki>{{NASTRO comment|primary-unnumbered=yes}}</nowiki></code>
| align=right | {{Category count only|Minor planet object redirects (unnumbered)}} items
|-
| [[:Category:Minor planet object redirects (non-primary)]]
| <code><nowiki>{{NASTRO comment|do-not-cat=yes}}</nowiki></code>
| align=right | {{Category count only|Minor planet object redirects (non-primary)}} items
|-
| [[:Category:Cometary object redirects (primary)‎]]
| <code><nowiki>{{NASTRO comment|type=comet}}</nowiki></code>
| align=right | {{Category count only|Cometary object redirects (primary)}} items
|-
| [[:Category:Cometary object redirects (non-primary)]]‎
| <code><nowiki>{{NASTRO comment|do-not-cat=yes|type=comet}}</nowiki></code>
| align=right | {{Category count only|Cometary object redirects (non-primary)}} items
|}
