wrong density? (or mass)
There seems to be something wrong with the density. (It could be also the mass.) I used a spread sheet with formula, and got 4×1019 kg with the given density 1.97. Other way, when I put the given I got 3.8 as density. That would mean the density is roughly half for that mass, or mass roughly double for that density. According to the source, the mass and density are for the whole system (object and satellite). Figure 348 ± 45 km is given as an "effective diameter" for the whole system. The maximum there is just under 400 km, and even that will not get over 7×1019 kg with the given density. Unless basic geometry does not work on TNO's... 109.240.149.76 (talk) 23:44, 26 September 2021 (UTC)
