How long does it take light from sun to reach Uranus?

It takes approximately 2 hours and 40 minutes for light from the Sun to reach Uranus when the two are at their closest distance. This is due to the vast distance between the Sun and Uranus in our solar system.

The days on this planet may last 42 earth years and the seasons may last 21 earth years?

Because Uranus' axis of rotation is in the plane of its orbit, the poles of the planet face the Sun. This means that each pole is illuminated for half of its 84.3 (Earth) year orbit, making a day on the planet last roughly 42 Earth years.

How many hours are there in 42 minutes?

There are 60 minutes in one hour. Therefore, 42 minutes is equal to 42/60 = 0.7 hours.


How many days in 42 hours?

Simply substract 24 hours (equals one day) from 42. Thus, there is 1 day and 18 hours in 42 hours.


Which planet is tilted more than 90 degrees on its axis?

In relationship to its plane of orbit around the Sun, the planet Uranus's axis is tilted at about 97.7 degrees to the perpendicular! Sometimes it's said to be tilted at only about 82.3 degrees. It just depends how you define the "North pole".(97.7+82.3=180, of course.)Therefore, in comparison with Earth's plane of orbit around the Sun, and Uranus's own plane of orbit around the Sun, Uranus is "on its side"! Its North pole doesn't point towards the Pole star as Earth's North pole does.It takes just over 84 Earth years for Uranus to make one complete orbit of the Sun. Meanwhile it is spinning on its axis, about once every 17 hours. At one point in Uranus's orbit around the Sun, and due to the fact that the planet is 'on its side', its North pole points almost directly at the Sun. 42 years later, as Uranus has moved to the other side of the Sun, its North pole is pointing away from the Sun and is in total darkness. So each pole experiences about 42 years of being in the light, and then 42 years of darkness.(For more information, pictures and diagrams, see Related links below)


How long does it take to sunrise and sunset in Uranus?

Since Uranus has a 92% tilt on its axis, the sun sets every 42 years. One side of Uranus faces the sun for 42 years while the other side faces darkness at the same time. Then when 42 years go by, this reverses.
