A "failed star" is a loose term, to describe a ball of hydrogen and helium, that didn't have enough mass to initiate nuclear fusion and become a "real" star. These "stars" are known as brown dwarfs. [See related question]. Some people believe Jupiter is a failed star, but this is not the case.
People often refer to Jupiter as a "near star" because it is one of the brightest objects in the night sky and can be easily seen without a telescope. However, Jupiter is actually a gas giant planet in our solar system, not a star, as stars undergo nuclear fusion to generate energy, while planets like Jupiter do not.
Yes, there is a star with that name.
Good question. It is unlikely, though, as there simply is not enough matter in Saturn to have enough gravitational pull to produce enough heat at the centre to induce thermonuclear reactions to form a star - even a small one. Even Jupiter, which is much more massive, is nowhere near massive enough. This idea has been talked about for years. Arthur C Clarke, probably the greatest science fiction writer (well, one of the greatest with Isaac Asimov) and visionary of the 20th century suggested that very thing in 2011 - the sequel to 2001: A Space Odyssey. In the sequel, the alien monolith appears in Jupiter's Giant Red Spot and causes Jupiter to ignite into a star, thus becoming 'Lucifer' the source of energy which helps thaw Europa's oceans (one of Jupiter's moons) and create a spurt in the evolution of life there. Sadly, however, this is all fiction. Even where planets much larger than Jupiter have been discovered in orbit round other stars, these too have been simply too small to become suns in their own right. So to call Saturn a 'failed' star implies that it could have possiblybecome a star but somehow failed to achiieve this. In the same way, I have 'failed' to become a mother. But as I am male, then I could not possibly have 'failed' in this task (I am a father though - twice over!). So, as Saturn could never be a star to begin with, in that sense, it could not have failed.
An asterisk (*)go back to school...!
A brown dwarf. That is the name given to a star that has a little less mass than the minimum required to sustain fusion.
No, and it never will. It is a failed star.
Jupiter is considered a failed star because it is made mostly of gas and lacks the mass needed to sustain nuclear fusion like a true star.

A protostar is a star the is developing as is on the way to starting nuclear fusion. A brown dwarf is a failed star, one that failed to gather enough mass to start fusion.
Assuming that the question refers not to a falled (??) star but to a failed star, the answer is that it is a star that does not have enough mass for hydrogen fusion to be sustain. Such stars are also known as brown dwarf stars.Assuming that the question refers not to a falled (??) star but to a failed star, the answer is that it is a star that does not have enough mass for hydrogen fusion to be sustain.

No, Jupiter is not a failed star. It is a gas giant planet made mostly of hydrogen and helium, while stars are made mostly of hydrogen and undergo nuclear fusion to produce energy. Jupiter does not have enough mass to sustain nuclear fusion and become a star.
No, Jupiter is not a failed sun. It is a gas giant planet that did not have enough mass to ignite and sustain nuclear fusion like a star.
the name of a lucky star is a shooting star
