Iota Carinae (ι Car / ι Carinae) is a star in the constellation Carina. It is one of the brighter stars in the nighttime sky. It also has traditional names Aspidiske, Scutulum or Turais (Tureis).
Iota Carinae is of spectral type A8 or F0, making it likely a large and powerful white to yellow-white star. Due to precession, Iota Carinae will be the South Star in about 8100 CE.
Iota Carinae should not be confused with Asmidiske (ξ Puppis), a slightly dimmer star residing in a nearby section of the sky.
