Buys
Thrust
A buy pushes the coin along its path. Mass is the log of market cap, capped, so no coin can crush the rest.

How it works
in 30 seconds.
No jargon. Four things to know.
- 1
Launch a coin
A normal pump.fun coin, created in one transaction from your wallet. You are its creator.
- 2
It becomes a planet
It appears on the live map above. The higher its market cap, the heavier the planet.
- 3
Trading moves it
Buys push it forward. Sells slow it down. Sell too hard and it flies off the map.
- 4
3 orbits = buyback
When it circles a bigger planet three times, it becomes a moon. At that moment its own fee fund buys the coin on the market and burns it.

Thrust,
brake,
capture.
One N-body system. Every coin launched here is a body in it.
Sells
Brake
A sell slows it down and pushes it out. A coin that sells hard is ejected and leaves the map.
Orbits
Capture
Three full orbits around a heavier body make a moon, listed as "moons of $X" on the big one's page. Past 20% of total mass, a coin becomes the star.
Fees, split
and locked.
pump.fun creator fees go through a split that is locked in the launch transaction.
To the coin's own well
70%
On each capture, the moon's well buys back that moon and burns it. Each coin only ever buys itself back. Gravity picks the moment.
To the launcher
30%
The launcher is the creator: the wallet of the dev buy.

Why launch
here. Why hold.
What you get, in plain words.
For the creator
- You keep 30% of your coin's creator fees for as long as it trades. It is locked in the launch transaction: nobody can change it, not even us.
- Your coin gets a built-in buyback from day one: the other 70% goes to its own fund, which only ever buys your coin.
- Every visitor sees your planet on the homepage map. Become the star and you sit in the middle of it.
- Your track record is public on your creator page: every coin you launched here, and where it is now.
For the holder
- Each coin has a buyback fund that grows with every trade. You can see it live on the coin's page.
- When the coin is captured, that fund buys the coin and burns it: fewer coins in circulation.
- Selling slows the planet and can throw it off the map. A planet off the map cannot be captured, so no buyback until it comes back.
- Each coin page shows the orbit progress towards its next capture, and every buyback already done, with its transaction.
Questions.
The short answers.
Is this a real coin?
Yes. Every coin launched here is a normal pump.fun coin on Solana, traded on pump.fun, then on PumpSwap once it graduates. Planets marked "demo" are not coins: they only exist so the map is not empty.
What is a "well"?
Each coin's own buyback fund: a wallet that receives 70% of the coin's creator fees. It only ever buys that one coin, and only when the coin is captured. What it buys is burned.
Does the site take a cut?
No. Creator fees are split 70% to the coin's well and 30% to its creator. The split is written in the launch transaction, and the site checks it on-chain before showing a coin as live.
Can someone move my planet on purpose?
Only by trading the coin, like everyone else. The simulation only reads on-chain trades, and anyone can replay it from the public trade list and get the exact same result.
What if my planet is absorbed or ejected?
Nothing happens on-chain: the coin keeps trading as usual. It just leaves the map, and comes back on the outer ring at its next trade.
Is this financial advice?
No. Memecoins are very risky and most go to zero. Only use money you can afford to lose. gravity is not affiliated with pump.fun.
