What is the planet Vulcan?

Planet Vulcan, in addition to being a fictitious planet in Star Trek from which Spock comes from, is a hypothetical planet that many astronomers in the 19th century believed that it may have existed. This planet was supposed to have low mass and be closer to the sun than Mercury, so close that the telescopes of the day could not solve it because of the huge brightness of the sun itself. Vulcan, if existed, could have surface temperatures even warmer than mercury temperatures, which peak at 700 degrees K (801 degrees F), perhaps more than a thousand degrees. 1840-1843 when he tried to predict the movement of the planet on the basis of Newton's theories. The procession of his Perhelion (point at which is closest to the sun) around his orbit was about 43 arches over a century of what Newton's theories would predict. Since every other planet in the solar system moved in a way precisely predicted Newton's theories, it was mysterious and the planet Vulcan was caused as a cause of inconsistency. In 1846 Le Verrier discovered a Neptune planet on the basis of the same principle, a disorder in the Uranus orbit. This galvanized astronomers to look for Le Verrier.

In 1859, astronomers began to report small black spots that pass through the surface of the Sun, which were considered to be the planet Vulcan. Over the next six years, about a dozen of alleged observations of black dots have been carried out, but transit has not always been able to remorize on the basis of past observations. In 1866, the observation of the planet Vulcan began to decline, but earlier observations were considered "evidence" of the existence of the planet, such as Le Verrier and in 1860. In 1867, two reliable astronomers claimed that in 1867 they saw the Vulcan planet near the sun during eclipse, but it was probably a star. Le Verrier died in 1877, still convinced that he discovered two newplanets.

In 1915 it was clear that there was never a planet Vulcan. Einstein's new theory of relativity precisely explained anomaly as a by -product of the Gravity Field of the Sun. The new numbers that predicted his theory were exactly the observation. In more modern times, astronomers have intensively searched the region around the Sun for all rocky bodies, such as volcanoid asteroids that could circulate in the stable gravity area next to the Sun. However, the observations excluded anything greater than about 60 km (37 miles) in width. Today, the search for volcanoid objects continues. Many scientists are skeptical and claim that Yarkovsky Effect, which changes the orbit based on high-enters photons on the asteroid right next to the star, would cause any volcanoid asteroid orbit to become unstable, either sinking to the sun or affecting mercury.
