Meet the 60 identities →The sky behind your story
The stars are not decoration. They place your beginning somewhere real: at one exact time, above one place on Earth, beneath a sky that belonged to that moment.
AsterNym reconstructs it using astronomy — showing the stars above you, the Moon’s phase, the planets’ positions and your Birth-Sky Star.
