Its story

10 Virginis is an orange K-type star in Virgo, 238 light-years away. Its surface burns cooler than the Sun's and so it gives off that warm, coppery light the eye recognises at once with a little training. It shares the sky with Spica and with the immense Virgo cluster of galaxies, though that one hides far further away. The light crossing the atmosphere tonight left its envelope during the eighteenth century, in the heart of the European Enlightenment.
