How fast to travel to stay in daylight forever?

[edro]

I know this has been answered a few times.... but I forget.

How fast do you have to fly in a plane (or whatever), following the sun, so stay in daylight forever? (or until you slow down)

I am guessing it is something like 5000 miles in 3 hours (extremely rough estimate, using L.A. to N.Y., and time zone difference), making it about ~~~1600 miles/hour.

Does that sound about right?

 

as fast as the earth rotates

circumference of the earth/ 24
approx 25,000 miles / 24 = 1042mph

A source on Google says the cirumference is 24,000 miles.... so 1,000 miles per hour?

Edit: Yeah, what he said ^

The earth rotates once ever 24 hours. The circumference is about 25,000 miles. To stay in one "spot" you'd need to travel at 25000/24 = 1050 mph.

You know in the Mummy? Well, they really could not have run that fast.

You can go slower if you're not at the equator.

that is a great point!

If you're at the north pole...just stand still

A really good idea (except during winter).

In the "winter," live at the south pole?

Yeah, that's what I was thinking. Because all you have to do is span the distance of 1 time zone in 1 hour, and you are back where you started. And I know it isn't 1050 miles between here and Central time zone...at least I don't think it is.

you'd have to travel faster the higher up you were aswell

like if you were 3 miles up:

earths radius = 3963 miles = diameter of 24900.26 / 24 ~ 1037 mph

radius +3 miles = 3966 miles = diameter of 24919.11 / 24 = 1038 mph

visit my country during the summer, then you will be in daylight the whole time

Woa, you post from Iceland? Very :beer:

Every woman I have seen in Iceland looks like a supermodel.

I'll be the first to admit that I am no mathematician. But wouldn't 1000 MPH basically keep you in the same position, relative to the sun? Daylight lasts for say, 12 hours. Doesn't that give you some room to play with?

Just alternate between the Arctic and Antarctica once every 6 months, you will see daylight year round.

yes, but he asked how fast to stay in daylight forever

I see. Forever, being the operative word.
