Venus solar day
A Venus solar day is the interval between two successive sunrises at the same location on Venus, which is much longer than an Earth day.
Also known as: day on Venus, Venus day
How big is it?
116.8 days
Solar day · approximate
Typical recorded range: 116.7 days to 116.9 days.
A little perspective
About the same scale as Red-cell lifespan.
Red-cell lifespan: Red-cell lifespan is the average time a human red blood cell remains in circulation before being removed from the bloodstream.
Measurements, assumptions & sources +
Venus solar day
One Venus solar day lasts about 116.75 Earth days, approximately 10.09 million seconds. This differs from Venus’s longer retrograde sidereal rotation period.
The marked solar day is calibrated. Unmeasured illustration details are representative.
Red-cell lifespan
A typical human red blood cell circulates for about 120 days, or 10.368 million seconds, before removal. Lifespan varies with cell condition and health; this is not a transit time.

The marked typical circulating lifespan is calibrated. Unmeasured illustration details are representative.
