No. What am I missing? The moon isn't that far away from the earth. If the moon was reflecting the sun from that view, then surely we would see the
earth lit up, too.
No. It's the moon. The moon was just above the horizon over the darkened limb of the earth at 22:46 UT on 10/29/15 where the ISS camera was pointed.
Here's a simulated view using Orbiter 2010 and orbital elements of ISS from that day:

The time was confirmed by matching up land features from later in the video:

Camera orientation was confirmed by observing the video from about 10 minutes before when the earth's terminator was visible below.

To those discussing previous videos of the moon from ISS where it isn't over-exposed but is very close to the bright sunlit earth surface, the camera
has an auto-gain function. It was designed to capture the daylit portions of earth and ISS, so it evaluates the exposure by the histogram of the
image. Since most of the image is black when pointing at the moon in the OP video, it ends up over-exposing the moon in an attempt to compensate for
the mostly-black image. This is quite normal. If it happens to be near a daylit limb of the earth it's quite possible to see it properly exposed, or
if the camera can zoom in enough that the moon occupies a substantial portion of the frame it may be possible for the autogain to correct itself to an
appropriate level.
