Current positions and passes use your observing location.

Orbital elements are checked before predictions are shown.

    Behind the observatory

    Planet and sky positions are calculated locally with Astronomy Engine. Star catalog and constellation sources are credited in the included data notices.

    Planetary surface maps by Solar System Scope, based on NASA imagery, under CC BY 4.0; rendered on spheres with illustrative lighting and rotation. Venus radar terrain uses simulated color and a 180° texture registration correction. 3D rendering by Three.js (MIT).

    The 45-world reference atlas links NASA and USGS / IAU sources for each fact and point of interest. Surface markers are overview references; giant-planet bands and poles have no fixed storm longitude. Added moons are standalone surface atlases, with no precise sky-position model. Asteroid orbits use NASA/JPL SBDB osculating snapshots in a two-body approximation, displayed within two years of the element epoch. These are approximate heliocentric references, without a local-sky ephemeris. Unmapped objects use neutral illustrative bodies. Coverage gaps in spacecraft mosaics remain visible. Climate and historical facts carry their context separately from calculated sky positions and Earth’s timestamped weather layers.

    The star atlas uses the celestial sphere: stars are shown at a common visual radius, not at their physical distances. Compact mode compresses orbital distances; True AU mode preserves them. Planet sizes are enlarged in both modes. Local sky includes geometric horizons and does not predict cloud cover or light pollution.
