What Is the Snapchat Planets Feature?

There’s a paid feature in Snapchat called Snapchat Plus. When you activate it, it shows you what position you hold in someone’s “solar system.”

Snapchat has turned each friendship into a planet — like Mercury, Venus, Earth, Mars… just like the real ones in space.

The friend who interacts with you the most — sends snaps, talks, keeps a streak — is shown as Mercury.
Mercury is the closest planet to the Sun, and in Snapchat, it means you are someone’s number one best friend.

  • When I Was a Kid…

When I was in lower grades, I had a best friend. We used to eat lunch together every day, play games, and talk all the time. Everyone used to say, “These two are best friends!”

Snapchat does something similar. When someone uses Snapchat Plus, they can see who their closest friend is — and that person is shown as the Mercury planet.

What Does Mercury Mean on Snapchat?

When I visited a friend’s profile and saw the Mercury planet, I realized that I was their closest friend according to Snapchat. It feels like a digital friendship medal.

If you’re someone’s Mercury, it means:

  • They send you the most Snaps
  • Your streak with them is strong
  • You are number one on their best friends list

The Snapchat Planet Order

Snapchat Planets feature showing the order of best friends from #1 to #8 with planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune displayed on two smartphone screens.

Snapchat uses these 8 planets to show friend ranks:

  1. Mercury – #1 Best Friend
  2. Venus – #2
  3. Earth – #3
  4. Mars – #4
  5. Jupiter – #5
  6. Saturn – #6
  7. Uranus – #7
  8. Neptune – #8

The closer you are to someone, the closer your planet is to the “Sun.”
The Sun here means the person whose friend ranking you’re part of.

How I Became Someone’s Mercury?

When I understood how this feature worked, I tried to become my cousin’s Mercury.

Here’s what I did:

  • Sent them Snaps every day
  • Stayed active in chats
  • Replied to their stories
  • Built and maintained a Snapstreak — without breaking it

In just 5 days, I saw that I had become their Mercury. It felt like Snapchat gave me a trophy.

  • Some Important Things

Here’s something I really want to say:

  • You can be someone’s Mercury, but they might not be yours.
    This feature is one-sided. Each person has their own solar system.
  • This is only visible to Snapchat Plus users. If you use the free version, you won’t see the planet feature.
  • The goal of this feature is fun — it’s not a real test of friendship.

When Can Mercury Change?

Snapchat Planets visual showing a user's position changing from Mercury to Venus, indicating a drop in Best Friend ranking with Bitmoji characters and planets.

I was someone’s Mercury once, but a few days later, I became their Venus.
This happened because:

  • I broke the Snapstreak
  • I got busy and stopped sending Snaps
  • My cousin interacted more with someone else

So being Mercury is not permanent. It keeps changing — that’s why if you want to stay Mercury, you have to stay active.

Final Words – What I Learned

When I understood what Mercury means, I learned the value of both Snapchat and friendship.
But I also realized that real friendship isn’t about emojis or planets — it’s about the heart.

This feature is just Snapchat’s way of showing your activity and connection.
So enjoy it, but don’t overthink it. Don’t turn friendship into a number.
