To calculate the distance from Uranus to the Sun in light hours, we need to know the distance between them in kilometers and divide it by the speed of light.

The average distance between Uranus and the Sun is approximately 2,870,972,200 kilometers.

The speed of light is approximately 299,792,458 meters per second.

Converting kilometers to meters:

2,870,972,200 kilometers = 2,870,972,200,000 meters

Now, let's calculate the distance in light hours:

Distance in light hours = (Distance in meters) / (Speed of light in meters per second)

= (2,870,972,200,000 meters) / (299,792,458 meters per second)

= 9.578

Therefore, Uranus is approximately 9.578 light hours from the Sun.
