Mars

Mars is catalogued in this registry as a planet, held in the frame of Sol, from Solar system (curated).

Registry id MARS · source layer solar · provenance RAW — read directly from a source catalogue, unaltered

Open Mars 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.

Each row carries its own uncertainty and its own source. Where a row says no uncertainty is published, that is what the catalogue says — it is not a claim that the value is exact.

Orbit

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 SOL at epoch 2000-01-01 12:00:00 UTC (JD 2451545). Gravitational parameter of the primary: 1.3271244×10^20 m³/s². Semi-major axis in astronomical units uses the IAU 2012 definition (1 au = 1.495978707×10^11 m exactly).
