Top panel: Comparison of the best fitted orbits of X7 projected on the sky by Ciurlo et al. (2023) and Peißker et al. (2024b), which are shown as solid black and red lines, respectively. Bottom panel: Three-dimensional separation between X7 and candidate stars, used to constrain its origin based on an alternative orbital solution for X7 (Peißker et al. 2024b) as a function of time. The three stars shown, S18, S42, and S71, have fully constrained orbits (von Fellenberg et al. 2022). Notice that their closest approach to X7 over the past 200 years is between 1950 and 2000 at a three-dimensional separation >4000 au.
