The '''Fornax Dwarf Spheroidal''' (formerly known as the '''Fornax System''') is an elliptical [[dwarf galaxy]] in the [[constellation]] [[Fornax]] that was discovered in 1938 by [[Harlow Shapley]]. He discovered it while he was in [[South Africa]] on photographic plates taken by the 24 inch (61 cm) Bruce refractor at [[Boyden Observatory]], shortly after he discovered the [[Sculptor Dwarf Galaxy]].<ref>{{cite journal | author = Shapley H | date = 1938 | title = Two Stellar Systems of a New Kind | journal = Nature | volume = 142 | issue = 3598| pages = 715–6 | bibcode = 1938Natur.142..715S | doi=10.1038/142715b0}}</ref>

The [[galaxy]] is a satellite of the [[Milky Way]] and contains six [[globular cluster]]s; the largest, [[NGC 1049]], was discovered before the galaxy itself. The galaxy is also receding from the [[Milky Way]] at 53 km/s. It mostly contains [[population II]] stars.
