She did say she needed to rest her eyes as staring at a screen for too long was affecting her.

Several minor errors.

Time does not depend on where you are im space, it is c the universal constant, but rather upon your velocity through space.

Also Uranus's axial tilt is 98°, in essence putting it on its side so it kind of rolls round its orbit like a bowing ball. A year is easy enough to determine, but a day is harder to establish as the sun doesnt rise or set in the usual sense.

But other than that its pretty good.

I was under the impression that time in space is completely irrelevant because there is no one to measure it.
1 year, 10 years or a million years means nothing in the cosmos.
It is only us, as humans on this planet who have the need to measure it for our own purposes.

AFAIK Einstein's theorems don't need an observer for time to pass.

I could well be wrong as I am more of a lover than a physics genius.
