My daughter came home from school upset about something I had never heard of before. Her boyfriend had checked his Snapchat and seen that another boy ranked above her in his list. Now she was the one who had to explain herself.
The thing she had to explain was a planet.
That sentence sounds absurd. I know it does. But if your teenager uses Snapchat, it probably sounds familiar. The feature behind this moment is real. It has affected real relationships, and most parents I talk to have no idea it exists.
Here is what you actually need to know.
What Is Snapchat Doing With Planets?
Snapchat introduced a feature called the Friend Solar System through its paid subscription tier, Snapchat+. The idea is simple. You are the Sun. Your top eight most-active friends orbit you as planets. They follow the same order as the real solar system from Mercury to Neptune.
The person you snap and chat with the most becomes Mercury. Your number two becomes Venus. This continues all the way out to Neptune, which represents your eighth most-interacted-with friend. You access the system by tapping a badge on a friend’s profile. The app then shows you which planet you are in their world.
For a full breakdown of what each planet looks like and what each position means, this guide to snapchat planets covers all eight in detail.
Why This Is More Than a Fun Feature
Most features like this stay in the background. Users interact with them, might find them amusing, and move on. The planet system did not stay in the background.
The Wall Street Journal ran a story documenting what happened when teenagers started using this feature in real relationships. A fifteen-year-old girl from New York found out her boyfriend had ranked a male friend above her. She was Neptune. That other friend was Mercury. She told the Journal it caused a real argument and real hurt.
She was not the only one. The Journal found this pattern playing out across the country. Teenagers were treating the app’s ranking as a verdict on the actual health of their friendships. Mercury meant things were good. Neptune meant something was wrong with the relationship.
Snapchat took that feedback seriously. The feature launched as on by default for all Snapchat+ subscribers. After the coverage and the feedback, they changed it to off by default. Every new subscriber now has to go into settings and turn it on manually. Snapchat issued a statement acknowledging that the feature could feel good for users who ranked high. It could feel just as bad for those who did not.
That change tells you something important. The company itself recognized that making a ranking system visible to teenagers had consequences they did not fully anticipate.
How the Ranking Actually Works
Understanding the mechanics matters here, because the system measures something narrower than most parents or teenagers assume.
Snapchat calculates each position using recent interaction data. Direct snaps carry the most weight. Chat frequency counts. Story replies register. Streak consistency plays a role. Response speed appears to factor in when two friends are close in overall activity. The system looks at a rolling window of recent behavior. What you did last month matters far less than what you did this week.
See this breakdown of the snapchat solar system for the full mechanics behind how positions shift and what signals Snapchat actually tracks.
The key thing to understand as a parent is what the ranking cannot measure. It cannot see a phone call. It cannot see a real conversation. It cannot see two people sitting together in the same room. It only sees what happens inside the Snapchat app over recent days.
A teenager who calls their best friend every evening but does not snap them daily will rank lower. Someone who sends quick photos back and forth will rank higher, even with a shallower connection. The app has no way to distinguish those two friendships from each other.
What to Actually Tell Your Teenager About This
The honest conversation is more useful than telling your teenager the feature does not matter. To many of them it clearly does. Here is what is actually worth saying.
The ranking reflects recent app activity, not how much someone cares about them. A friend who texts instead of snapping will rank lower. Same for someone who calls instead of chatting in the app, or who just had a busy week. Nothing about the friendship changed. The position is a measure of one specific behavior pattern in one specific app. It is not a measure of loyalty, history, or affection.
The other thing worth saying clearly is that the system is one-directional. You can be someone’s Mercury while they sit at a lower position in your own rankings. The two calculations run independently. A teenager seeing that someone ranked them as Neptune while they ranked that same person as Mercury might read that as a problem. It is not. It is two separate activity measurements that did not line up.
The Bigger Pattern Here
Snapchat’s planet feature is one example of something happening across most of the major apps teenagers use. Social activity is being turned into data. Data is being made visible. And teenagers are using that visible data as social currency in ways that have real emotional consequences.
This is not an argument against the apps. It is an argument for understanding what the apps actually measure. Teenagers often assume the measurement is more meaningful than it is.
The ranking system reflects engagement frequency inside one app over recent days. It does not reflect the full weight of a human relationship. When your teenager knows that difference, the number on the screen holds a lot less power over them.
That is the conversation worth having.
