The modern understanding and harnessing of electricity can be attributed to multiple inventors and scientists.
The "hour of Venus" is often associated with Venus being visible in the evening or morning sky, but it doesn't have a specific definition related to Earth Hour. Earth Hour is an annual event where participants turn off non-essential lights for one hour to raise awareness about climate change and energy conservation. The hour of Earth Hour typically occurs on the last Saturday of March at 8:30 PM local time. Therefore, the concept of "hour of Venus" does not directly correlate with Earth Hour.
An hour on Neptune is approximately 16.1 Earth hours long. Neptune has a longer rotational period compared to Earth, which is why its days are much longer.
1 day = 1 360 degree rotation and that is also 24 hours, so the shift per hour is 360/24 = 15 degrees /hour
