Orbit - Solar System 3D
A calm window to the planets
Free · Designed for iPad. Not verified for macOS.
把手机放在桌上，看太阳系天体沿真实轨道静静运转。可近观、可对比、可让时间快进到 2050 年。一处安静的沉浸空间。
Set your phone on the desk, turn it landscape, and let the solar system quietly come to life. The Sun breathes. The planets trace their orbits. The stars settle into the dark.
Ten worlds, up close.
The Sun, all eight planets, and the Moon — rendered from 2K NASA-based maps. Earth's drifting clouds and city lights, Saturn's shadowed rings, a living, glowing Sun. Drag to spin, pinch to zoom, and get close to each one.
Orbits in motion.
The planets follow JPL-based Kepler orbits across the years 1800 to 2050. Pause, play, or speed up time — from six hours to a full year every second — and watch the whole system dance.
See the true scale.
Line the planets up two ways: an easy-to-read layout, or their real average distances to scale in AU. Then compare sizes, the length of a year, and how long sunlight takes to reach each world.
A quiet place to linger.
Leave it running and, after a while, the controls fade away — just the planets, slowly turning. A single tap brings them back. An optional, softly synthesized ambient tone can play along, even with your phone on silent.
Chinese & English.
Switch languages anytime — the science, comparisons, and sources all come with you.
No ads. No subscriptions. No account. Orbit runs fully offline and keeps nothing about you.
The solar system, on your desk — quietly turning, always there.
