In the real sky
- Pick an anchor star: start from the brightest one. A very bright point that doesn’t twinkle may be a planet.
- Use only 4 to 7 bright stars: more than that and the shape gets lost. The classic figures rely on bright stars too.
- Give it a name: an animal, an object, a place that matters to you.
- Note the season: the stars visible at a given hour change through the year, so write down the date and time.
A shape like this is what astronomers call an asterism. It will never be official, but it’s a handy way to say “those three stars over there.”
On paper and photos
- Photograph the night sky and draw lines in a photo editor
- Print a free star chart, lay tracing film over it and draw
- Poke pinholes in black card and hold it up to a light
Comparing the methods
| Method | Good for | Downside |
|---|---|---|
| Real night sky | Real stars, a memory that lasts | Depends on weather and light pollution |
| Paper or photo | Great as a gift or craft | Takes time |
| Name-based app | Instant, different for every person | Not the real star positions |
Make one in the app and redraw it
The sample name and journal text in these screenshots were typed in Korean; the app itself runs fully in English.
Build it from a name and birthday
In My Constellation, enter a name and date of birth on the first tab, My Sky, and a star layout with connecting lines appears. The same input always draws the same constellation.
Redraw the lines
Tap Draw Your Lines, tap one star, then tap another to link them. Tap an existing line the same way to erase it. The meaning of your sign (element, guardian star, lucky number) never changes, and Restore original lines brings back the first shape.
Choose the night sky
The round colour buttons above the sky switch between Midnight, Dawn, Aurora and Desert Night.
FAQ
Can I register my constellation officially?
No. Constellation boundaries and star names are set by the IAU, which doesn’t take requests from individuals. See buying a star name.
Can I include a planet?
Planets move against the stars, so within weeks your shape would break. For a lasting shape, use stars only.
