Facts

  • Its planet GJ 1214 b is a classic 'sub-Neptune', a kind of world the Solar System does not have.
  • 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 68.2986 ± 0.0652 mas, Gaia DR3 4393265392168829056 (Gaia Collaboration 2023, A&A 674, A1)
