but what a way to go.

my money is on an earth satellite, Mercury would be a similar-ish size on the disk of the sun.
As for the wings (I presume you mean solar panels), some satellites have the solar panels on its walls,

Looks like a tumbing satellite to me.

I timed the transit and found the duration to be 29s.
The Sun's angular diameter is about 30"
I used a CD to draw a circle and I played and paused the video and plotted a course.
Length of transit 10.7cm
Equatorial diameter of disc = 12cm
This was drawn parallel to line of transit.
Angular speed was then calculated to be 0.92 arcsecs per second.
A sidereal second is 86164/86400 = 0.9973 seconds of wallclock time.
Rough enough calcs but my money is on it being a geostationary satellite.

At first glance, I thought the video was showing a massive white circle moving across the sun :blush:

Thinking about my post more.
For the object to be geostationary - and cross the disc of the Sun - the image capture would have had to be at or near one of the equinoxes (me thinks). I have no information on date of capture so can't progress that line of thought.
I think it's time for me to climb out of the rabbit hole...
