Isotropic Kinematics from the Gaia Early Data Release 3&quot; (https://arxiv.org/pdf/2103.03289) mentioned. In there, one estimate of the number of these objects is Nisc &lt;~ 7.2 × 10−5 AU−3 Which (my, probably wrong, calc) implies roughly one inside the orbital volume at the radius of Saturn&#x27;s orbit at any time.</p><p><a href="https://hackerpaper.kaipfister.de/p/2103.03289/">Paper and discussion history</a>.
