Alp

Its story

Alpha Lacertae is the brightest light of Lacerta, the modest Lizard that Polish astronomer Hevelius drew between Cygnus and Andromeda in 1687 to fill a gap in the northern sky. She is a white main-sequence star, twice the Sun's mass and a little more than twice its radius, settled just 103 light-years away. Alone, she holds together a constellation that would otherwise be almost invisible.
