Binary star system in constellation Cetus
HD 3443 is a binary system composed of medium-massmain sequence stars in the constellation ofCetus aboutlight years
This binary star system, with an orbital semimajor axis 8.9AU , has not had any circumstellar dust detected as of 2020.[ 8] AU from the stars, planetary orbits with a semimajor axis beyond 1.87AU would become unstable due to the influence of the binary companion.[ 10]
The star system is enriched in oxygen compared to theSolar System , having 140% of solar oxygen abundance,[ 11] [ 2]
