## What is Interplanetary Clock?

Explore time across the solar system with Interplanetary Clock.

View live local solar time for planets and moons including Mars, Earth’s Moon, Titan, Europa, Jupiter, Saturn, Neptune, and more using a deterministic interplanetary clock engine.

Designed as both a scientific visualization tool and an educational reference, the app computes planetary local solar time using geometry-aware orbital models, time-scale conversion, and validation workflows inspired by NASA NAIF SPICE reference systems.

FEATURES

• Planetary and moon world clocks
• Local solar time across multiple celestial bodies
• Deterministic clock engine
• Offline-capable clock rendering
• Earth-relative observer longitude support
• Scientific validation and approximation reporting
• Beautiful clock-style interface inspired by the iPhone Clock app
• Support for planets, synchronous moons, and retrograde rotators

SCIENTIFIC NOTES

Interplanetary Clock uses deterministic astronomical modeling and validation workflows to characterize planetary local solar time behavior across multiple bodies.

Some bodies and features are quantitatively validated against external SPICE reference workflows, while others are presented as characterized approximations with explicit validation boundaries.

This app is intended for educational, visualization, and scientific exploration purposes. It is not intended for spacecraft navigation or operational flight use.
