This image is rumored to have been taken by the International Space Station and is estimated to be around 3-5 thousand miles in diameter and parked somewhere in the Earth’s stratosphere.
The image was published on November 12, 2013 by the ‘Correio Braziliense’, a local newspaper in Brazil’s capital city. The photo was published in conjunction with the announcement of the re-opening of that city’s planetarium, which had been shuttered for 16 years.
I found the newspaper’s webpage, which featured this image and as a native speaker of Brazilian Portuguese, I found and browsed the planetarium’s site and found no reference to this image.
The uploader says he has inquired the planetarium directly about it, in his upload, made on March 29, 2014.
Neither he nor I have any idea what this object is.
