Expected motion from a stationary background object (black line and gray track), given the 2022 astrometry. We assume µ_α = 16.915 mas yr⁻¹ µ_δ = −49.3l8 mas yr⁻¹ and π = 37.2539 mas. Blue curves represent orbits drawn from the posterior distributions of the orbit fit. We expect a background object to have a significantly different trajectory in separation compared to an orbiting planet over the next year. The vertical red lines mark the epochs of HST/NICMOS and Keck/NIRC2 observations discussed in the text.
