It was once known as the marine star due to its proximity to the river constellation Eridanus.  It has a small B star companion which itself has a C star rotating around it, and its fate may be as a rare oxygen-neon dwarf, although a nova is more likely. Of spectral class B8, it radiates 100 times the energy of its constellations larger and cooler alpha star, and it is losing mass at about 70 trillion tons per second, giving it a relatively short life span of several million years. With a name meaning "left foot" in Arabic, FTP, name this blue-white supergiant, the Beta star to Betelgeuse in the constellation Orion.
