I'm guessing that you're talking about Earth hours and Pluto years.1 Pluto year = 89,865.65 Earth days = 2,156,775.6mean solar Earth hours
An earth day is divided into 24 hours.
1 year = 8,765.81277 hours
the Earth makes 1 rotation every 24 hours the Earth makes 1 revolution every 8766 hours.
8,766 hours.
8,766 hours.
10 hours
1/2 year = 4,382.9 hours
The ratio will always be the same so the answer will be 500 to both questions
24 hours
1 Earth rotation = 24 hours.
In the course of a year, every point on Earth has the sun up for half of the time. That would be 1/2 of 365 days or 4,380 hours.
