No Man's Sky: Types of star classes, what they are and how they work

 No Man's Sky star classes help us identify what types of stars there are in the universe and their characteristics. Here we show you all the classes and what each one means.


One of the ways that No Man's Sky classifies each and every type of star in its universe is through stellar classes (also known as space or spectral classes). Below in this section of our complete guide, we show you all the types of star classes that are in the game and how each one works.

What are star classes?

Stellar class (also known as spectral) is a method used in No Man's Sky to classify stars and the types of planets and resources found in them. Each star in the game is assigned a class made up of three characters (such as "G2m" ). The translation of these characters would be the following:

  • The first character, a capital letter: identifies the class of the star (its color).
  • The second character, number: provides a range of heat within a specific class, it can range from 0 to 9 (the lower the number, the hotter it is in that star).
  • The third character, a lowercase letter: indicates any rarity within the star (such as specific elements such as hydrogen).
Star class can be consulted at any time by pointing at a star from the Galactic Map view, scanning a planet from space, opening the analysis viewer, or from the log menu with the space guide.

Types of Star Classes

Knowing the types of stellar class will help you in your travels through the universe since this can give us a lot of information about the stars and their planets beforehand. This way we will travel more effectively depending on the planets that we are most interested in recognizing first.

In No Man's Sky, 11 stellar classes are known to date and these identify the class of a star, its temperature, and its color. They can be the following:

A class

  • Star color: white.
  • Temperature range: between 7,500 and 10,000 K.
Hydrogen in large quantities and ionized metals can be found in these stars.

Class B

  • Star color: white or blue.
  • Temperature range: between 10,000 and 30,000 K.
On the planets of these stars, you can find some of the rarest resources and materials in the entire game. You can fly to these stars with the Indian Hyperturbo upgrade.

Class E

  • Star color: green.
  • Temperature range: unknown.
Most planets in these stars tend to have tropical biomes and often contain rarer resources than usual. You can fly to these stars with the Hyperturbo Emelio upgrade.

Class F

  • Star color: yellow or white.
  • Temperature range: between 6,000 and 7,500 K.
These stars are the most common planets in the game, with a lot of common resources. You don't need any Hyperturbo upgrade to fly to these stars.

G-Class

  • Star color: yellow.
  • Temperature range: between 5,200 and 6,000 K.
As with Class F stars, in these we also find planets with common resources, they are among the most abundant in the universe. You don't need any Hyperturbo upgrade to fly to these stars.

Class K

  • Star color: orange.
  • Temperature range: between 3,700 and 5,200 K.
In stars of this class, you can find planets with quite a variety of fauna and flora and some rare resources. You can fly to these stars with the Hyper Turbo Cadmium upgrade.

L-Class

  • Star color: brown or red.
  • Temperature range: between 1,300 and 2,400 K.

M-Class

  • Star color: red.
  • Temperature range: between 2,400 and 3,700 K.
Like K-class stars, stars in this class have planets with some rare resources and a good variety of fauna and flora. You can fly to these stars with the Hyper Turbo Cadmium upgrade.

Class O

  • Star color: blue.
  • Temperature range: above 30,000K.
As with class B, some of the rarest resources and materials in the entire game can be found on the planets of these stars. You can fly to these stars with the Indian Hyperturbo upgrade.

T-Class

  • Star color: brown or red.
  • Temperature range: between 500 and 1,300 K.

Class Y

  • Star color: brown.
  • Temperature range: below 500K.
