# Is Naming a Star Real? An Honest Guide to Commercial Star Naming

> The star is real and its coordinates check out. The official naming right does not exist. What the IAU, the AAS and the planetarium society actually say, and how to tell an honest service from hype.

Answer in three layers: the star is real (an object from a genuine survey catalog such as HYG, with verifiable coordinates and distance); the name is symbolic (the IAU, the only body that officially names celestial objects, recognizes no commercial naming); and “registration” or “official certification” does not exist. To judge a service, check whether it publishes its catalog, gives coordinates and IDs you can verify, and plainly states that the name carries no official status. We do all three.

## Unpacking the question: star, name, registration

- **The star itself** — Real: from genuine survey catalogs, with RA/Dec (J2000), distance and catalog IDs you can trace and verify
- **The memorial name** — Symbolic: printed on your certificate and memorial space, meaningful to you, entered in no astronomical database
- **Registration / official naming right** — Does not exist: the IAU is the only body that officially names celestial objects, recognizes no commercial naming, and there is no “official star registry”

## What the IAU and the astronomical societies actually say

Start with the body that decides. The International Astronomical Union is the only organization with the standing to name celestial objects, and it does so through its Working Group on Star Names, drawing on historical and cultural tradition rather than on anything anyone paid. It does not sell names, and since 2022 its rules bar personal names outright: no people, no animals, no brands, no political events.

The professional societies have said the same thing for decades. The American Astronomical Society puts it plainly in its own FAQ: there is no place where you can purchase a star, and the names sold by commercial services are not recognized by anyone in the scientific community. The International Planetarium Society took that position in 1988 and has held it since, noting that the names scientists actually use are never sold, and that the star charts bundled with purchased names have been altered from real catalog data.

What this means in practice is simple. The same star can be sold by several companies under different names, each one recorded only in that company’s own database. No outside body issues the registration, and none could. If a service tells you the IAU has recorded your name, that statement is false, whichever company is making it.

## What an honest service looks like: a checklist

Most of the controversy around “is it real” comes from the packaging. Filter any service, including ours, with four questions: (1) Do they name their catalog and data source (a genuine survey like HYG or Hipparcos, not a self-made “star registry”)? (2) Do they give you coordinates and a catalog ID you can verify in software like Stellarium? (3) Do they clearly state the name has no official status and is not recognized by the IAU? (4) Is it a single transparent price, or does fine print add “registration fees”? Only services that pass all four are worth your money.

## The claims you will see, and what they actually mean

- **“Officially registered”** — It means registered with the company you bought from. There is no public register of star names, so there is nothing else to register with. The phrase is doing marketing work, not legal work.
- **“Certificate of ownership” / “deed”** — A keepsake document. It conveys no legal title to the star, and no document could, because a celestial body is not a thing that can be owned, transferred or inherited.
- **“Kept in a vault”** — A private ledger held by the company. There is no public register to check it against, so being kept in a vault and being kept in their database are the same thing.
- **“Includes an official star chart”** — Check the coordinates yourself. Enter the RA/Dec from the certificate into Stellarium or any catalog and see whether a star is actually at the position the chart marks. If they disagree, you have your answer about the chart.
- **“Name a star after anyone”** — On a certificate you can print any name you like. In the IAU catalog, personal names have been barred since 2022. Both statements are true, and only one of them appears on your certificate.

## How to verify your own star after purchase

When you have the certificate, type its RA/Dec into any planetarium software (Stellarium, the free SkySafari tier) and the star should sit exactly where you pointed; then match the catalog ID and magnitude. If it checks out, it is real. That verification rests on astronomy, not on the seller’s word. Step-by-step instructions are in our locating guide.

## If you already bought a star from another service

First, the reassuring part: you were not cheated, unless the seller promised you official standing. What you bought was the star itself plus a keepsake document, and both are still there. To settle it properly, do three things. Take the RA/Dec from the certificate and look it up in Stellarium or any catalog; if the coordinates check out, the star is real. Then find the page you bought from and see whether it claimed “official registration” or IAU recognition; if it did, the advertising was false, and none of that touches your memorial. And the name will not appear in any astronomical database. That was always true, and it does not change what the thing means to you.

## How we differ from traditional star registries, side by side

Since the test is four questions, here are the two side by side: a traditional “star registry” mostly assigns a star from a list and prints a certificate that looks official; ours is computed, and gives you the real star at the zenith of the moment and place you enter, with verifiable coordinates, a 3D return to that night’s sky, and a private memorial space by default. The price sits on the same line too: one tier, $19.99, no add-ons. The full comparison table is on our comparison page, including the rows where we lose.

## The IAU doesn’t recognize it. So why does the memorial still hold?

With the honest half said, back to the real question: if there is no official standing, why is it still worth doing? Because a memorial never depended on a registry to work. It depends on being there: a star with real coordinates, findable by anyone on any night, fixed by the moment and place they passed, and in that spot every year from now on. Official naming changes an entry in an astronomy archive; a memorial star changes what you see when you look up. The first needs authority. The second only needs you.

It is also why verifiability matters: the coordinates check out in any planetarium app, the catalog ID traces to a real survey, and the certificate hides nothing. Because every part survives scrutiny, the thing is actually dependable. A symbol is not a weaker version of the real; it is a different kind of real.

## FAQ

**So is buying a memorial star a scam?**

No. Honest services sell a keepsake industry: buyers know there is no official naming right and pay for a bond with a real star. The problem is services that dress it up as “official registration”. The checklist above filters them out.

**Can two companies sell the same star?**

Yes. There is no registry, so “uniqueness” is each company’s own ledger. What we can promise: the same moment and place always produce the same star (the determinism comes from the astronomy), and the coordinates you receive verify in any catalog.

**Why do certificates look so official?**

Formal-looking certificates are an industry habit, which is exactly why you should read the small print: it should say the naming is a memorial gesture and not recognized by the IAU. Every certificate and FAQ page of ours says precisely that.

**Is naming a star legal?**

Yes. Selling a symbolic name is a lawful keepsake business, and printing a name on a certificate breaks no rule. The problem is never the keepsake, it is the claim. If a seller tells you the IAU records the name, that claim is false, and no one can deliver it.

**Can I name a star after someone who is still alive?**

Commercially, yes, and people do it for births, weddings and anniversaries. Officially, the IAU bars personal names from its own catalogues altogether, so the question does not arise there. The name on your certificate is yours to choose.

**What does “officially registered” actually mean?**

In this industry it means registered with the company you bought from. A public register of star names does not exist, so there is nowhere else to register. The phrase is doing marketing work, not legal work.

# “命名一颗星”是真的吗?商业命名服务诚实指南

> 恒星是真的,坐标可查;「官方命名权」不存在。IAU、AAS 与国际天文馆学会的原话,以及怎么分辨诚实服务与营销话术。

分三层答:星是真实的(HYG 等真实巡天星表里的天体,坐标与距离可查证);名字是象征性的(商业命名不被 IAU 承认,IAU 是唯一有权正式命名天体的机构);“注册权/官方认证”不存在。判断服务是否诚实,看它是否公布所用星表、给出可核对的坐标与编号、并主动写清命名无官方效力。这三件事我们都做。

## 把问题拆开:星、名字、注册

- **恒星本身** — 真实:来自真实巡天星表,坐标(RA/Dec, J2000)、距离、编号全部可溯源查证
- **纪念名** — 象征:印在证书与纪念空间上,只对你们有意义,不进入任何天文数据库
- **注册 / 官方命名权** — 不存在:IAU 是唯一有权正式命名天体的机构,不承认商业命名,也不存在“官方星名登记处”

## IAU、AAS 与国际天文馆学会,原话是怎么说的

先说说了算的那个机构。国际天文学联合会(IAU)是唯一定名天体的组织,通过其恒星命名工作组(WGSN)依历史与文化传统审定,不看谁付了钱。它不售卖星名;2022 年起更明令禁止以个人命名,人物、动物、品牌、政治事件一律不收。

专业学会几十年来口径一致。美国天文学会(AAS)在自己的问答里写得很直白:没有任何地方可以买到一颗星;商业服务售出的名字「不为科学界任何人所承认」。国际天文馆学会(IPS)自 1988 年的立场声明起沿用至今:科学家真正使用的星名从不售卖,而随购买附赠的星图已被改动,与实际星表数据不符。

落到实践上很简单:同一颗星可以被不同公司用不同名字反复卖出,每一份只记在那家公司自己的数据库里。没有任何外部机构会颁发这种登记,也不可能有。如果有服务告诉你 IAU 已收录了你的名字,这句话是假的,不管它出自哪一家。

## 诚实服务的样子:一份自查清单

“是真的吗”这类问题,大部分争议来自包装。用这四问过滤任何一家服务,包括我们:① 公布所用星表与数据来源吗(HYG、依巴谷这类真实巡天,而不是自造的“XX 星表”)?② 给出可核对的坐标与星表编号吗(能放进 Stellarium 等软件验证)?③ 是否主动说明命名无官方效力、IAU 不承认?④ 一次性付费、证书内容写得清,还是靠“额外注册费/加急费”层层加价?四条都满足的,才值得谈。

## 你会看到的说法,以及它们实际是什么意思

- **「官方注册」** — 指登记在你购买的那家公司名下。并不存在公开的星名登记册,也没有别处可登记。这个词在做营销工作,不是法律工作。
- **「所有权证书」/「契约」** — 一件纪念文书。它不构成那颗星的法律所有权,也没有任何文书能构成:天体不是可以被拥有、转让或继承的东西。
- **「存于保险库」** — 公司自持的私人账本。不存在可与之核对的公共登记册,所以「存进保险库」和「存在他们数据库里」是同一件事。
- **「附赠官方星图」** — 自己核对坐标。把证书上的 RA/Dec 输进 Stellarium 或任何星表,看图上标的位置是否真有那颗星。对不上,那张图值多少就有答案了。
- **「可为任何人命名」** — 在证书上你可以印任何名字;而在 IAU 的正式星表里,2022 年起个人命名已被禁止。两句话都成立,只是只有一句会出现在你的证书上。

## 买完之后怎么自己验证

拿到证书后,把上面的 RA/Dec 输进任何星图软件(Stellarium、SkySafari 免费版),那颗星应当出现在你输入坐标的精确位置;再对照星表编号与星等。能查到的就是真的。这份能力不依赖卖家的信用,依赖的是天文本身。详细步骤见我们的寻星指南。

## 如果你已经在别家买过一颗

先说安心的部分:你没有上当,除非对方当时承诺了官方效力。你买到的是恒星本身加一份纪念文书,这两样都还在。想彻底确认,做三件事:① 把证书上的 RA/Dec 输进 Stellarium 或任何星表,坐标对得上,那颗星就是真的;② 翻回当时的购买页,看它有没有写「官方注册」「IAU 承认」这类话,写了就是宣传失实,与你的纪念无关;③ 那个名字不会出现在任何天文数据库里。这一点从第一天起就是如此,不改变它对你的意义。

## 与传统“星空注册”的差别,摊开来讲

既然判据是四问,就把我们和传统“星空注册”(star registry)服务并排放一次:传统服务多是从名单里分配一颗星、印一张看起来正式的证书;我们是由你输入的时刻与地点,算出那一刻天顶的那颗真实的星,坐标可核对、可 3D 回望、默认私密的纪念空间。价格也摆在同一行:单档 $19.99,无附加。完整对比表在我们的对比页上,包括我们“输掉”的那些行。

## IAU 不承认,纪念为什么仍然成立

把诚实的部分说完,回到真正的问题:没有官方效力,为什么还值得做?因为纪念从来不靠登记簿生效,靠的是「在场」:一颗坐标真实、任何人在任何一晚都能重新找到的星;一个由 TA 离开的那一刻与地点确定、此后每年都在的位置。官方命名改变的是天文档案里的一个词条;纪念星改变的是你抬头时看到的东西。前者需要权力,后者只需要你。

这也是「可核对」为什么重要:坐标能放进任何星图软件验证,星表编号能溯源,证书上不藏话。正因为每一条都经得起查,「可以靠」才成立。象征不是弱化版的真实,它是另一种真实。

## FAQ

**所以买纪念星是上当吗?**

诚实服务不是骗局,是一种纪念品产业:买家清楚知道没有官方命名权,买的是与真实恒星的联结。问题出在包装成“官方注册”的服务。避开它们即可,清单在上文。

**不同公司会卖同一颗星吗?**

会。商业命名没有登记制度,唯一性是各家自己的账本。我们能承诺的是:同一时刻与地点永远确定同一颗星(确定性来自天文算法),并保证你得到的坐标在任何星表里都查得到。

**为什么证书看起来那么正式?**

证书样式模仿正式文书是行业习惯,这正说明要读小字:看它是否写明“纪念性命名,不获 IAU 承认”。我们每一张证书与每一页 FAQ 都写这一句。

**给星星命名合法吗?**

合法。售卖象征性命名是正当的纪念品生意,收钱在证书上印个名字不违反任何规定。出问题的从来不是纪念品,是那句承诺:如果卖家说 IAU 会收录这个名字,那句话是假的,也没有任何人能兑现它。

**可以为在世的人命名一颗星吗?**

商业上可以,而且很多人正是为出生、结婚、纪念日在做。官方层面,IAU 的正式星表一律不收个人命名,所以那个体系里不存在这个问题。证书上写什么名字由你决定。

**「官方注册」到底指什么?**

在这个行业里,它指登记在你购买的那家公司名下。公开的星名登记册并不存在,所以也没有别处可登记。这个词做的是营销工作,不是法律工作。
