# How to Read Your Certificate & Find Your Star in Any App

> The two most important lines on your certificate are the coordinates and the catalog ID — the star’s address in the universe.

The RA and Dec (J2000) printed on your certificate are standard astronomical coordinates: type them into the search bar of Stellarium or any planetarium app and it will point to your star. Catalog IDs (HIP or Gaia) usually work as search terms too. Combined with the live compass on your 3D star page, you can know exactly where to look tonight.

## What each line on the certificate means

- **Memorial name & dedication** — The name you chose and one line for them — commemorative by design
- **Constellation, date & place** — The real constellation the star lives in, plus the moment and place used
- **Catalog ID** — HYG/HIP or Gaia ID: the internationally recognised identity of the star, traceable independently
- **RA / Dec (J2000)** — Right ascension and declination — the coordinates that locate it in any sky app
- **Distance & magnitude** — Distance in light-years and a brightness reference
- **QR code** — Scans straight to the star’s 3D page

## Find it in Stellarium (desktop & web)

Open stellarium-web.org or the desktop app: (1) open the search box (F3 usually); (2) type the coordinates like “05h55m10.3s +07d24m25s” (RA 05:55:10, Dec +07:24:25); (3) press Enter — the view centres on your star. In the web settings you can switch RA/Dec display format and epoch; make sure it reads J2000.

## Finding it on your phone

- **Stellarium Mobile** — Free tier works; search accepts coordinate entry
- **SkySafari / Star Walk 2** — Most versions search by coordinates or catalog IDs
- **Our 3D star page** — No app needed: the star page itself returns you to that night’s sky, with a live direction guide

## “Found it — now what?”

Many people pause the first time they “see” their star: it may be faint, hard for the naked eye — that is fine. Binoculars, a small telescope or a long-exposure photo will show it. Knowing it is there is part of the memorial. It is never clouded out; the coordinates never expire.

# 证书怎么读?怎么在手机或电脑上找到你的星

> 证书上最重要的两行是坐标与星表编号——它们就是这颗星在宇宙里的门牌号。

证书上的 RA(赤经)与 Dec(赤纬)(J2000)是通用天文坐标:在 Stellarium 或任意星图 App 的搜索栏输入它们,就能定位到你的星;星表编号(如 HIP 或 Gaia ID)也常可直接检索。配合 3D 星页的实时方位提示,今晚就能知道该往天空哪里看。

## 证书上每一行是什么意思

- **纪念名字与题献** — 你为 TA 选的名字与想说的话——名字是纪念性的
- **星座与日期地点** — 星所在的真实星座,与计算所用离世时刻/地点
- **星表编号** — HYG/HIP 或 Gaia 编号:国际通用的身份标识,可独立溯源
- **RA / Dec(J2000)** — 赤经与赤纬——在星图软件里定位它的坐标
- **距离与星等** — 距地球多少光年、肉眼/望远镜可见性参考
- **二维码** — 扫开直达这颗星的 3D 星页

## 在 Stellarium 里找到它(电脑与网页)

打开 stellarium-web.org 或桌面版:1) 打开搜索框(通常按 F3);2) 输入坐标,格式如「05h55m10.3s +07d24m25s」(即 RA 05:55:10、Dec +07:24:25 的写法);3) 回车,视图会居中到这颗星。网页版右上角设置里可切换 RA/Dec 显示格式与历元,记得核对为 J2000。

## 手机 App 推荐

- **Stellarium Mobile** — 免费版可用;搜索栏接受坐标输入
- **SkySafari / Star Walk 2** — 多数版本支持按坐标或星表编号检索
- **本平台 3D 星页** — 不用任何 App:打开星页即可回到那一刻的夜空,含实时方位指引

## 「找到了,然后呢?」

许多人第一次「亲眼」看到那颗星时会愣住:它可能很暗,肉眼难辨——没关系,望远镜、双筒或长曝光照片都能看到它。知道它在那里,本身就是纪念的一部分。它不会因天气消失,坐标永远有效。
