Creating a sci-fi world, story, or game is an exciting adventure. One of the most fun parts is naming the planets that bring your universe to life.

A great planet name can spark imagination, set the mood, and make your story or game feel real.

Why Planet Names Matter in Sci-Fi?

A planet’s name is more than just a label. It’s a doorway to your world’s story. A name can hint at a planet’s environment, culture, or history. For example, a name like “Zorath” sounds mysterious and alien, while “Eryndor” feels lush and magical. 

The right name can make players or readers feel connected to your world. It can also set the tone—whether it’s a dangerous, barren wasteland or a vibrant, glowing paradise. With cool planet names, you can create a universe that feels alive and unforgettable.

How to Choose the Perfect Planet Name?

Picking a planet name doesn’t have to be hard. Here are a few tips to help you find the perfect one:

• Think About the Planet’s Features: Is it a desert world, a frozen tundra, or a jungle paradise? The name should match the vibe.
• Consider the Culture: Does the planet have a unique civilization? Names can reflect the language or history of its people.
• Keep It Memorable: Short, catchy names are easier for readers or players to remember.
• Mix and Match Sounds: Combine soft or hard sounds to create names that feel alien, magical, or futuristic.

Now, let’s dive into over 300 cool planet names, sorted into categories to spark your creativity. Each section includes names that fit different sci-fi themes, from fantasy to futuristic.
