Interactive Solar System Model (Planetary Orrery)

Keplerian Relative Orbital Periods•Interactive Play, Pause & Speed Engine•Clickable Planetary Fact Dossiers•Saturn Rings & Distinct Planet Spheres

Explore the Motions of Our Cosmic Neighborhood

Bring the Solar System to life. Our animated digital orrery models the orbital journeys of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune around the central Sun with accurate relative Keplerian speeds.

Accelerate time up to 30x, pause motion, or click any planet to reveal its distance from the Sun in Astronomical Units (AU), orbital velocity, and fascinating astronomical facts.

How to Use the Interactive Solar System Model

Use the play/pause button and speed slider to accelerate planetary motion.

Click or tap on any planet to inspect its orbital period, distance, and facts.

Observe how inner planets orbit dramatically faster than distant ice giants.

Frequently Asked Questions

What is an astronomical orrery?

An orrery is a mechanical or digital model of the Solar System that illustrates the relative positions and orbital motions of the planets around the Sun.

Why do inner planets orbit much faster than outer planets?

According to Kepler’s Third Law of Planetary Motion, planets closer to the Sun experience stronger gravitational attraction and must travel faster along much shorter orbital paths.

Are planet sizes and distances drawn to scale?

True astronomical distances and diameters differ by orders of magnitude (the Sun is 109 times wider than Earth). Digital orreries use logarithmic or normalized scaling to ensure all planets remain visible on screen.
