Among the most elusive creatures in Pokemon Go, Cosmog stands out as a particularly challenging acquisition for dedicated trainers. This comprehensive guide reveals the exact methods to add this celestial Pokemon to your collection while avoiding common pitfalls.
Cosmog represents a Legendary Psychic-type Pokemon originating from the Alola region, serving as the initial form in an evolutionary line that culminates in powerful legendary creatures. Its transformation progresses to Cosmoem, with the ultimate evolution branching based on temporal conditions. When evolving Cosmoem during daylight hours, trainers obtain Solgaleo, the sunne Pokemon, while nighttime evolution yields Lunala, the moone Pokemon.
This cosmic entity first appeared in Pokemon Go during September 2022, coinciding with the Season of Light event that introduced multiple Alolan legendaries.
How to find Cosmog in Pokemon Go
Legendary Pokemon maintain their rarity even in preliminary forms, making acquisition particularly challenging for trainers. While some legendary encounters depend on random chance, Cosmog follows a more structured but limited availability pattern.
Cosmog represents a significant exception among rare Pokemon—this celestial being cannot be encountered through standard wild spawns, egg hatching, raid battles, or Field Research tasks. Its exclusivity makes strategic planning essential for successful acquisition.

The sole method for obtaining Cosmog involves completing either Special Research or Timed Research questlines. These research initiatives become accessible only during designated timeframes, creating urgency for participating trainers.
Cosmog has featured prominently in two major Special Research events: A Cosmic Companion and Starry Skies. These limited-time quests may still be available in your game interface. Navigate to the Special Research section and verify whether either quest remains active for completion.
For trainers undertaking A Cosmic Companion research, only the initial segment requires completion to secure Cosmog. Conversely, Starry Skies demands fulfillment of all four research stages before rewarding participants with this nebula Pokemon.
After successfully acquiring Cosmog, implement the buddy system strategy by designating it as your walking companion. This approach generates essential candy resources through distance traveled. You’ll need to accumulate 125 candies total to advance Cosmog through its complete evolutionary progression.
Evolution planning requires careful consideration of your desired legendary outcome. Solgaleo excels as a powerful Psychic/Steel-type attacker with impressive bulk, while Lunala serves as a formidable Psychic/Ghost-type with unique defensive properties. Consider your team composition needs before committing to either evolution path.
Maximize candy acquisition by combining walking distance with strategic item usage. Employ Pinap Berries during any Cosmog encounters to double candy rewards. Utilize rare candies from raid battles and research breakthroughs to accelerate your evolution timeline.
Common mistakes include evolving Cosmoem without verifying local time conditions, resulting in unintended legendary forms. Always confirm your device’s time settings and desired evolution outcome before proceeding. Future event opportunities may provide additional Cosmog encounters, so monitor seasonal announcements and prepare research task completion in advance.
