An error in "The Hungry Sea"?


It is dark night outside the windows of the Jupiter 2 when dr. Smith tries calling the Chariot.

In the next scene the chariot is moving over land during day time.

Daylight.
- A few minutes ago it was pitch black.
- It's a strange planet.
I thought for sure we'd have three or four more hours before dawn.
And we've crossed the ice.
- And it's morning.

And then Dr. Smith calls.

And if this is the same call Smith started when it was black outside, I find it very hard to believe that it could have got that might lighter so fast.

So my theory is that Smith tried and failed to make contact, and then tried again an unspecified time later, after the sun rose, and succeeded on this second try.

But what about the sun rising so fast that night turns into daylight in just a few minutes? I hear that in the tropics on Earth sunrise and sunset are much faster than in other latitudes, and so the the night could also become day much faster.

And what about dawn coming 3 or 4 hours earlier than Professor Robinson expected? As far as I remember, nobody ever mentioned that the days and nights on Priplanus were longer or shorter than Earth days. Thus we can suppose that the rotation rate of Priplanus might possibly be about one full roatation in about 24 Earth hourse - give or take a few hours.

In a 24 hour rotation, Earth rotates 15 degrees every hour, and so 45 to 60 degries in 3 to 4 hours. So Earth rotates 1/8th of a full rotation in 3 hours and1/6th of a full rotation in 4 hours.

Nothing could make the rotation rate of a planet speed up or slow down drastically without destroying all life on it, and maybe destroying the planet itself. But at that time the planet was whipping around its sun, approaching its closest point. and so the angle to the sun may have also been changing rapidly. This might combine with the planet's constant rotation rate to make the night shorter than normal nights, and might help explain the shorter time between night and daylight on this one day.
