So this is where you say you have to go.

You came in hot, unannounced, all velocity and mystery — too fast to belong, too strange to stay. We noticed you on 1 July 2025, when the ATLAS telescope in Chile caught you slipping past, pretending not to care that we were watching. 

You’re just the third of your kind to wander into our neighborhood. Third, but no less disruptive for it.

Sure, the lab coats gave you a tidy name — 3I/ATLAS — because scientists like labels, the way lovers like explanations. Third interstellar object, spotted by ATLAS. Clean and clinical, sterile even.

But it didn’t explain the feeling that something from elsewhere had dropped by, looked around, and decided we weren’t home. Oh well, it would have been a game-changer if you stayed.

Your path gave you away. That hyperbolic curve — no intention of settling down, no chance of being held by the Sun’s gravity. You were never ours. Just passing through, carrying ice and dust forged around another star, dragging a coma like a sigh behind you.

You came closest in late October, skirting the Sun at about 1.36 astronomical units, just outside Mars’ orbit. Close enough to feel the heat, not close enough to burn. 

Then in December, the 19th to be exact, you brushed past Earth at a polite 1.8 AU. Safe distance. Always careful not to get too close. That should’ve been the clue.

We stared anyway. Hubble, James Webb, every expensive eye we have trained on you, trying to read your surface, your chemistry, your past. 

We asked the usual questions: Where did you come from? What are you made of? What can you tell us about places we’ll never reach?

You answered the way all departing girlfriends do — by revealing just enough to make us wonder, then turning away.

Now you’re accelerating out, back to the dark between stars. No forwarding address. No promise to write. Just a brief visit, a data set, a memory.

Safe travels, 3I/ATLAS. Thanks for stopping by. We won’t pretend we didn’t feel it when you left.
