Vulcan was a small planet proposed to exist in an orbit between Mercury and the Sun. Attempting to explain peculiarities of Mercury’s orbit, the 19th-century French mathematician Urbain Jean Joseph Le Verrier hypothesized that they were the result of another planet, which he named “Vulcan”. No such planet was ever found, and Mercury’s orbit has now been explained by Albert Einstein‘s theory of general relativity.  Searches of NASA’s two STEREO spacecraft data have failed to detect any Vulcanoid asteroids.
