Size equivalent of the shadow of Sagittarius A*

From the Event Horizon Telescope (EHT) Collaboration image of the black hole at the centre of our galaxy (Sgr A*), researchers can measure the size of its shadow to be about 52 micro-arcseconds on the sky. This is about the size of a donut on the Moon as seen from Earth.
