You might be talking about Mercury, if not I'm going to assume you are talking about Vulcan, the hypothetical planet that during the 19th century was believed to exist between Mercury and the sun and was supposed to be the cause of Mercury's unusual orbit. Indeed Edmond Modeste Lescarbault believed he observed its transit in 1859 reports rolled in of sightings of it. But no proof of it's existence was ever found (no predictable orbital perimeters). Today many believe he either observed a sunspot or maybe a comet/asteroid.
Modeste Mignon was created in 1844.
