Autonoe is catalogued in this registry as a moon, held in the frame of Jupiter, from Planetary satellites — mean elements (JPL SSD).
Registry id JPLSAT_528 ·
source layer jplsats ·
provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented
Open Autonoe in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.
These are the sourced elements. This page does not print a position: a position is a function of time, and a single one dated to the bake would be stale the moment it was read. The registry composes a position for any date, past or future, from these elements — open the scene below and set the clock.

Elements are expressed in the frame of
JUPITER at epoch
2000-01-01 12:00:00 UTC (JD 2451545). Gravitational parameter of the primary:
1.2664332×10^17 m³/s². Semi-major axis in astronomical units uses the
IAU 2012 definition (1 au = 1.495978707×10^11 m exactly).

| Coverage | 437 moons of Mars→Pluto beyond the 22 curated majors; mean elements at epoch referred to the ecliptic/Laplace/planet-equator plane per row, rotated to the J2000 ecliptic (Horizons-anchored conversion); nodal/apsidal precession not modelled; radius only where JPL publishes one (24); the 22 curated-major rows are not discarded — their a/e/i + radius reconcile onto the curated moons as corr/alt (erase none) |
