CD-46°11540 is most commonly known as Gliese 674 and informally Proxima Arae. It is the nearest red dwarf known to have a planet and was the second nearest known exoplanet to the Sun when discovered. The star is type M3 V and is about 35% as massive and 42% as wide as the Sun and believed to be 550 million years old. It was once classed as an orange dwarf and a possible sub-dwarf. It was discovered by John Tome at Cordoba in Argentina. The planet is a Hot Neptunian in a tight orbit that has a similar eccentricity as Mercury. It's about 70% the mass of Neptune and 12 times that of Earth. It is unclear what its nature would be. It orbits at 0.04 AU, which is closer than the habitable zone, which is 0.13 to 0.15 AU.
