We found a
second Earth.
Now it has a currency.

Kepler452Coin is the commemorative currency of humanity's leading candidate for a second home — a super-Earth sitting in the habitable zone of a sun just like ours, 1,400 light-years out.

Earth's older, bigger cousin

In July 2015, NASA's Kepler Space Telescope located the first potentially rocky super-Earth ever found inside the habitable zone of a star nearly identical to our own. Catalogued Kepler-452b, it orbits a Sun-like star roughly 1,400 light-years away in the constellation Cygnus — close enough, on a cosmic scale, to feel like a neighbor.

Its year runs 385 days, its radius is about 60% wider than Earth's, and its star has already been burning for six billion years — roughly a billion and a half years longer than our own Sun. If there's a version of Earth further along in its story, this is science's leading candidate. Kepler452Coin exists to mark that discovery.

Flight Plan

Four phases to touchdown

A sequence, not a promise — each phase unlocks the next.

01
Live

Signal Acquired

Identity, lore and launch materials assembled. First crew members assemble around the discovery. You're reading this in real time.

02

Descent

Token deploys on-chain, liquidity locked and verifiable, contract published across official channels only.

03

Habitat Established

Community growth pushes, listing on trackers and aggregators, exchange conversations pursued.

04

Terraform

Long-horizon goals: broader ecosystem, community-directed treasury, and sustained, unglamorous building.

Comms — Standby

The crew assembles soon
