ユルバン・ルヴェリエ
The name "Vulcan" has been used for various other fictional planets, in and out of the Solar System, that do not correspond to the hypothetical planet Vulcan, theorized by Urbain Le Verrier shortly after his discovery of Neptune to orbit the Sun closer in than Mercury. The planet Vulcan in the "Star Trek" franchise, for instance, is specified as orbiting 40 Eridani A.
