Snapchat Solar System is a fun part of Snapchat Plus that shows your closest friends in a space-themed design. In this system, you are the Sun, and your best friends are shown as planets orbiting around you. The closer a planet is to the Sun, the stronger your friendship is on Snapchat. Each planet represents a different level of connection, based on how much you interact by sending Snaps, chatting, or sharing Stories. The Snapchat Solar System turns your friendships into a colorful and exciting experience, making it easy and fun to see who you are closest to.
