how many moons does mercery have?

Question

Answer 1

The spelling of the word "mercy" (as in Shakespeare's "The quality of mercy is not strained" speech) may have confused you? It is Mercury. (Same with the element Mercury used in thermometers.)

Mercury has no moons. There was once thought to have been an inner planet provisionally called Vulcan, which might have been a moon of Mercury befiore the Sun's gravity pulled it away but no-one could find it. The publication of Einstein's Theory Of Relativity showed why.

Vulcan was the name given to a small planet proposed to exist in an orbit between Mercury and the Sun in a 19th-century hypothesis.

Vulcan was proposed to explain a small perturbation in Mercury's orbit from the path predicted by classical Newtonian mechanics, technically called perihelion precession.

During Mercury's orbit, its perihelion advances by a small amount each orbit. The phenomenon is predicted by classical mechanics, but the observed value differed from the predicted value by the small amount of 43 arcseconds per century.

This idea and the name "Vulcan" was postulated by the French mathematician Urbain Le Verrier in 1859, closely following his spectacular success in "discovering" the planet Neptune in the same way — using only calculus. Various persons and astronomers around the world attempted to prove the existence of the said planet for another 56 years,

But this hypothesis was then rendered obsolete by Albert Einstein's theory of general relativity in 1915.

I don't think we even have a planet called Mercery. There's one called Mercury, though. Maybe that's what you meant. Keep working on that spelling!
