The “Friend Solar System” feature in Snapchat organizes users into different planets based on their level of interaction with a specific friend. Each planet represents a rank within the friend list of another user, indicating the closeness of their connection. The system uses the following planetary order to signify the proximity from closest to farthest: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
This hierarchy means that if you are assigned Mercury, you are the closest friend in that user’s list, often indicating high frequency and intimacy of interactions. Conversely, being assigned Neptune suggests a more distant relationship with less frequent communication. This feature provides a fun and engaging way to visualize and understand the dynamics of friendships within the platform.
