From Bulbapedia, the community-driven Pokémon encyclopedia.
The Stellar type (Japanese: ステラタイプ Stella type) is a type that exists only in Generation IX. Unlike other types, no Pokémon or moves bear it naturally, being exclusive to the Terastallized state of a Pokémon.

Uniquely, the Stellar type has no defensive properties, as a Stellar-type Pokémon will always retain its original typing's defensive properties. Offensively, Stellar-type moves are super effective against other Tera Pokémon; in practice, Pokémon that have Terastallized are weak to Stellar-type Tera Blast and Tera Starstorm in addition to any weaknesses of their current Tera Type. As such, outside of Terastallizing, any attempts to change a Pokémon's type into the Stellar type (such as the moves Conversion 2 or Reflect Type) will fail.
Additional effects
When a Pokémon Terastallizes into the Stellar type, it gains increased STAB for every move type, but only once per type; 2× for original types and 1.2× for every other type. After a move is used, no other moves of that same type will receive increased STAB from being Terastallized. In Tera Raid Battles, all moves will be boosted in this manner without limit. In its Stellar form, Terapagos similarly retains this boost at all times.
Stellar-type Tera Blast gains the drawback of lowering the user’s Attack and Sp. Atk stats by one stage, and Stellar-type Tera Starstorm changes to hit multiple opponents. Other moves cannot be changed into the Stellar type.
Pokémon
No Pokémon is naturally Stellar-type. All Pokémon in Pokémon Scarlet and Violet except Ogerpon can gain the Stellar type through Terastallization, but defensively, they are treated as their base type.
Special Terastallized states
Moves
These moves are naturally Normal-type, but they become Stellar-type and have special changes if the user Terastallizes into the Stellar type.

Trivia
- This is the only type to be exclusive to a transformation mechanic. Likewise, it is the only type a Pokémon can not be without the mechanic.
- Written in katakana, ステラタイプ (Sutera type) is an anagram of テラスタイプ (Terasu Type), the Japanese word for Tera Type.
- The Stellar type, along with the rest of the Terastal phenomenon, was created by Terapagos. Pokémon gain the Stellar Tera Type due to the influence of the crystals found in the Area Zero Underdepths.
- Terapagos cannot have any other Tera Type than Stellar.
