As of May 2024, we know of 3 stars (A, B, Proxima) and two planets (Proxima Centauri b and d) in Alpha Centauri system. The discovery of further one planet is disputed and another one disproven. This adds up to 5 known celestial bodies.

What will be the total number of known celestial bodies in Alpha Centauri system as of 2030-01-01? This includes:

  • stars

  • planets

  • moons

  • comets and asteroids

  • brown dwarfs

  • black holes

Only the discoveries that are considered proven by the relevant Wikipedia articles are counted.

For the purposes of this question, all objects within 1 light year from Alpha Centauri A are considered part of the system.

I do not bet on my own questions.
