Antlia (originally Antlia pneumatica, now Antlia alone, from Latin Antlia, "the pump") is a constellation created by Nicolas-Louis de Lacaille in 1752 in an attempt to cover the last few regions of the southern hemisphere sky that were still left without any denomination. It's a faint constellation, its brightest star, Alpha antliae, being an orange giant of magnitude 4.25. α Antliae is located roughly 370 light-years away and is a slightly variable star, but highly imprevisible.
