“…Kurth & Gurnett 2020;Burlaga et al Table 1. Known trans-Neptunian objects currently located beyond 100 au from the Sun: 2018 VG 18 was discovered in November 2018 at 123 au (Sheppard et al 2018;Sheppard, Tholen & Trujillo 2020), 2018 AG 37 was first observed in January 2018 at 132 au (Sheppard et al 2021), 2020 BE 102 was found at 111 au in January 2020 (Sheppard et al 2022) The current record holder is 2020 MK 53 found by New Horizons KBO Search-Subaru (Peltier et al 2022). For this object, the software discussed in Bernstein & Khushalani (2000) applied to the available data (six observations spanning three days at r ′ =26 mag) gives a barycentric distance of 156±4 au and the latest JPL's Horizons ephemerides give 160±22306 au (2460200.5 JD TDB) as the uncertainty grows exponentially over time for short data arcs.…”

Although the present-day orbital distribution of minor bodies that go around the Sun between the orbit of Neptune and the Kuiper Cliff is well understood, past ∼50 au from the Sun, our vision gets blurred as objects become fainter and fainter and their orbital periods span several centuries. Deep imaging using the largest telescopes can overcome the first issue but the problems derived from the second one are better addressed using data analysis techniques. Here, we make use of the heliocentric range and range-rate of the known Kuiper belt objects and their uncertainties to identify structures in orbital parameter space beyond the Kuiper Cliff. The distribution in heliocentric range there closely resembles that of the outer main asteroid belt with a gap at ∼70 au that may signal the existence of a dynamical analogue of the Jupiter family comets. Outliers in the distribution of mutual nodal distances suggest that a massive perturber is present beyond the heliopause.
