Alp
Its story
Alpha Antliae is the chief light of the Air Pump, the modest constellation Lacaille traced in honour of Boyle's vacuum pump. It is an orange giant on the asymptotic branch, forty-one times the radius of the Sun; one day —millions of years from now— it will end its life as a Mira variable, pulsating with enormous amplitude before fading.
