Euclidean distance between p Oph and each of the clusters σ Sco, δ Sco, and β Sco over the past 12 Myr. Ages and their corresponding uncertainties for σ Sco, δ Sco, and β Sco are indicated with a star symbol (taken from R23b and given in Table A.2). The vertical dashed gray line and gray area indicate the age and age uncertainties of p Oph, respectively. Prior to star formation, the motion of these clusters corresponds to that of their primordial clouds. In the upper panel, we show the distribution of times of minimum distance.
