Sham

Its story
Sham is the head of the little Arrow, one of the tiniest constellations in the sky, already catalogued by Ptolemy. Its name, from the Arabic «As-Sahm», means precisely «the arrow». It is a yellow G-type giant 425 light-years away: the light seen tonight set out when Cervantes had just published the first part of Don Quixote. The Arrow crosses the Milky Way like a dart thrown by some forgotten hand, piercing the river of stars of the northern summer.
