Facts

  • Its star, BD+60 2522, is a hot O-type star many times the Sun's mass.
  • Its distance comes from a Gaia parallax: the tiny yearly shift in its position as the Earth circles the Sun.

Where this comes from

  • Gaia DR3 parallax 0.3341 ± 0.0152 mas of its central star BD+60 2522, Gaia DR3 2014149897293278848 (Gaia Collaboration 2023, A&A 674, A1)
