Heliocentric gone wild

Note to myself: Heliocentric aphelion (Q) range: AD= 2.37 (epoch 1960-Oct-01) to AD= 5.23 (epoch 1979-Jan-01) * 10^3. Barycentric varies only from Q (AD) = (2.95 to 2.97) * 10^3. Barycentric solution much more stable over different epochs. -- Kheider (talk) 20:29, 12 February 2017 (UTC)

Trivia: 14FE72 passed 24AU from Uranus around 1950. (Horizons "Observer Location: @Uranus") -- Kheider (talk) 07:02, 13 February 2017 (UTC)

...what does any of this mean?

(I ask because having the heliocentric aphelion and SMA would be useful for comparing against the other extreme TNOs, whose own measurements are given as a bit of a random mix of helio and barycentric... and having read the above I feel even more lost. What's all the "AD" stuff? Are the formulas meant to imply 2370 to 5230AU and 2950 to 2970AU, or am I guessing wrong?) 2A00:23C8:9C94:DD01:859:4F80:1BAB:E51C (talk) 23:02, 14 September 2025 (UTC)

(...but then, the barycentric SMA given on the article is 2045AU, so... erm?) 2A00:23C8:9C94:DD01:859:4F80:1BAB:E51C (talk) 23:04, 14 September 2025 (UTC)
