Day length varies enormously across our Solar System. Jupiter spins fastest at 9h 55m per day; Venus is slowest at 243 Earth days. Mars's Sol of 24h 37m is the closest to Earth time — which is why Mars missions can operate on near-Earth schedules. Mercury's day is actually longer than its year.
Orbital periods span an even wider range. Mercury orbits the Sun in 88 days; Neptune takes 165 Earth years. If you were born on Neptune, you would be less than 1 Neptunian year old for your entire human lifetime.
The Solar System level of the Cosmic Dashboard shows real-time H:M:S clocks for all 8 planets simultaneously, with speed multipliers showing how each planet's day compares to Earth's. An orbital map displays all 8 planets in simplified circular orbits, with positions updating continuously.
