What is Cursa
Cursa means «the chair» in Arabic, alluding to its position at Orion's feet, right beneath Rigel, like a celestial footstool. It is a white star, slightly warmer than the Sun, lying 89 light-years away. Its calm and discreet light takes nearly a full century to cross the void towards us, a journey barely perceptible in the stillness of a February sky.
