How long is a day on Jupiter?
Data as of July 2026
9 h 56 minone full spin
A day on Jupiter lasts 9 h 56 min. That is 41% of an Earth day. Jupiter has no solid surface, so its day is the time the planet takes to turn once.

Why Jupiter's day is so short
Jupiter spins faster than any other planet: a whole day in under ten hours, for a world eleven times wider than Earth. Its cloud tops at the equator move at about 45,000 km/h, and the spin flattens it visibly at the poles.

Day length on every world
| World | Day (sunrise to sunrise) | One spin |
|---|---|---|
| Jupiter | 9 h 56 min | 9 h 56 min |
| Saturn | 10 h 39 min | 10 h 39 min |
| Neptune | 16 h 7 min | 16 h 7 min |
| Uranus | 17 h 14 min | 17 h 14 min (backwards) |
| Earth | 24 h 0 min | 23 h 56 min |
| Mars | 24 h 40 min | 24 h 37 min |
| Pluto | 6.4 Earth days | 6.4 Earth days (backwards) |
| Venus | 117 Earth days | 243 Earth days (backwards) |
| Mercury | 176 Earth days | 58.6 Earth days |
Earth's spin, against the stars, takes 23 h 56 min; the extra four minutes to a 24-hour day come from Earth moving along its orbit while it turns. On Jupiter the same effect is too small to matter.
