How far, from the Sun

1,450 light-years. To cross it:

  • Light1,450 years
  • Voyager 1's speed25.8 million years
  • Driving at 100 km/h15.6 billion years

Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.

Facts

  • Planet Hunters volunteers flagged its strange dips, up to 22% deep, in Kepler data.
  • Its dips are deeper in blue light, pointing to fine dust rather than a solid structure.

How it was found

  • It is named for Tabetha Boyajian, lead author of the 2016 study.

Where this comes from

  • Gaia DR3 parallax 2.2545 ± 0.0099 mas, Gaia DR3 2081900940499099136 (Gaia Collaboration 2023, A&A 674, A1)
