All 8 planets are positioned at their correct heliocentric ecliptic coordinates for the current date and time, computed on-device using VSOP87D truncated series (Earth, Jupiter, Saturn, Uranus, Neptune) and Meeus Keplerian elements (Mercury, Venus, Mars).

Accuracy: <0.3° longitude, <0.1% distance for all planets within the 1800–2200 validity range. Earth's position is accurate to <1 arcsecond.

Use the time warp controls to travel to any date — past or future. All planet positions, moon orbits, orbital precession, and axial rotation update deterministically.

Warp speeds: 1× (real-time), 1h/s, 1d/s, 1mo/s, 1yr/s. Jump directly via the date picker or ±1d/±1wk/±1mo/±1yr buttons.

True Keplerian ellipses with 3D inclination, ascending node, and argument of perihelion. Secular precession rates (Standish 1992) cause orbits to slowly rotate over centuries — visible at 1yr/s warp speed.

Mercury's perihelion advances +0.16°/century. Saturn's advances +0.54°/century.

14 natural satellites modeled: Earth's Moon (Meeus Ch.47), Mars (Phobos, Deimos), Jupiter (Io, Europa, Ganymede, Callisto), Saturn (Titan, Rhea, Dione), Uranus (Titania, Oberon), Neptune (Triton — retrograde).

All moons orbit in correctly tilted planes matching their parent planet's obliquity.
