250+ Best Planet Name Ideas For You

What was the last movie you saw? Last week I watched a sci-fi movie about space colonization. There were characters in the movie who were colonizing several planets for their own profit.

The movie was good, but what attracted me the most was the planet names. There were some unique planet names. From then, I was thinking about unique planet names. Planet name ideas are very useful nowadays. Not for only movies, but also for sci-fi novels,

fictional podcasts, or even for short videos. You will need unique ideas if you are a creator. And if you want to create a video on fictional planets, you will need planet names.

I have thoroughly researched planet names. I have got some unique names like Styx, Hydra, Hades, Nyx, etc. If you found these names interesting, read this full article to know many other interesting names.

Planet Naming Rules 

Naming a fictional planet is not so easy. You can easily set up a name for a fantasy character or a forest. But to set a name for a planet, you have to keep certain rules in mind.

You have to look at the rules set by IAU or the International Astronomical Union. What are the rules?

The first rule is, you have to decide the type of the planet. Decide how the planet is. Is it inhabitable? If there are aliens? If yes, then how developed are they? How do they look? What are their goals?

If you have analyzed these questions, then there are certain rules to follow. Those are –

  • Do not name a planet after pet animals or an individual.
  • Do not use names similar to existing planets.
  • Do not use more than 14 letters or characters.
  • Try to use only one word.
  • The name should be easily pronounceable. 

Now let me go deeper in the topic and discuss every kind of planet and their names.

Major Planets

There is a very simple rule to name a major planet. Just name it after a Roman or Greek god. You can distort their names a little too to name a major planet. If you want some other mythological names, they will work fine too!

Mythological or mythical names go fine with planets. Below I have given some ideas for major planet names. Check the list out.


Dwarf Planets

If your imaginary planet is a dwarf planet, then there is a naming rule too. These planets can be named after demigods or demons. You can use any creature’s name from any mythology as well. 

If you want a good name for your dwarf planet, then go through any mythology and check which creature’s name you can use. Below I am giving you some ideas for dwarf planet names. You can use them too.

Minor Planets

Do you know what a minor planet is? You can call a planet a minor planet that is yet not identified. Suppose, astronauts have discovered a planet, but they are yet to identify it. Then it can be called a minor planet.

Naming a minor planet has very simple rules. First see the month of discovery. Then check the number of discoveries in the month. Suppose, you discover a planet on 12th July. It is the 5th discovery in July. then you should assign NE to the planet.

But why NE? Because there is a rule. A month is divided into two parts. The first part starts from day 1 and ends on day 15. The second part starts from day 16 and ends on day 30. And each part of every month has a letter.

If you discover a planet in the first 15 days in January, then you have to assign the letter A. If you discover a planet in the last 15 days of January, you have to assign B. The second letter states the number of discoveries. If it is the first discovery of the month, then you should assign A. if it is the 2nd discovery, then B comes.

The last one is, the year of discovery. If you discover a a planet on 12th July, 2020, it will be called NE-2020. Simple rule!



Planets found outside our solar system are exoplanets. Exoplanets are named using a noun followed by a letter.
