A Never Ending Sunset

Question

How fast would you have to travel at sea level around the equator to make it appear as if is was sunset 24 hours a day?

Answer 1

There are sunsets at some other places than just the equator.

An eternal sunset can be had if you follow it at 60 deg and you only need a fast Jumbo. At 60 deg the distace around the Earth is half that at the equator

Answer 2

Not too fast, the rotation speed of Earth is only 469 m/s on the equator, and less on other places. A plane capable of exceeding the speed of sound can do that, but the only passenger plane capable of such flights, the Concorde, is no longer in service.

Answer 3

really fast

Answer 4

At Sea Level, AT THIS POINT IN TIME, you would have to travel approx. 1700 Kilometers per hour in a westerly direction. This is somewhat slower than 2 times the speed of sound.  AS A REFERENCE, The Concorde had an average cruising speed of 2140 Kilometers per hour, or "Mach 2.02".

PLEASE NOTE!  FOR THE SPEED TO BE CORRECT YOU WOULD HAVE TO BE DOING THIS AT THE EQUATOR, EXACTLY.

May I point out that is a "difficult and expensive speed to maintain" by any presently known vehicle, within the Earth's atmosphere. It is certainly NOT an energy efficient means of transport, nor a Environmentally friendly one.

It will, however, give you "an eternal sunset" . . . . till the crash!  .-)

Answer 5

The spped at which the surface of the earth is rotating

Answer 6

The speed of the Concorde when flying at supersonic speed. Some years ago, a group of scientists followed a lunar eclipse near the equator by flying a chartered Concorde westward.

But, more concretely, the circumference of the earth is roughly 40,000 km. This is actually the way the French made the first meter; as a fraction of a quarter of the circumference.

Since the earth spins in about 24 hours, you should maintain a speed of 40,000 / 24 or 1,666 km/h to follow the sun at the equator.

Answer 7

The earth has a circumference of about 24,000 miles at the equator. It turns once every 24 hours. So you'd have to travel at about 1,000 miles per hour. That's a rough figure, but it's easy to remember.

Answer 9

Pretty d**n fast.

Answer 10

Light travels at the speed of light (obviously) which is close to 300,000km per second, but that is not the speed you would need to travel at. The earth has a circumference of approximately 25,000km, and since there are 24 hours a day, you would have to travel at approx. 1000km/h (25000/24) to view a constant sunset.

Answer 11

the speed of light i guess.
