Pluto
No. If an object orbits the sun it is not considered a moon. Depending on its size, composition, and location it may be considered a planet, dwarf planet, asteroid, or comet.
That's easy its pluto

One moon is orbiting Earth and that is called The Moon.
A non proven theory is that eruption is a defence mechanism of our planet. When "comet elenin" came to near, Mercury fired. Our planet could do the same.
the planet you are looking for is Pluto it is about the same size as its moon and now scietist no longer call it a planet
No. Some comets periodically pass by the Earth, such as Halley's comet, but the Sun primarily creates the path they follow. Saturn's moon, Phoebe, may have originated as a comet.
Venus
Although rogue planet might escape a solar system or galaxy, its moon may remain since the moon is held in orbit by the planet, rather than a parent star. The moon will tend to go where the planet goes.
Pluto may not only be a dwarf planet but possibly a moon
There are only 8 planets, you may be referring to a dwarf planet. Please be more specific.
The pattern of motion of a moon is typically an elliptical orbit around its parent planet. This orbit is usually in the same direction as the planet's rotation and at a relatively constant distance. The moon also rotates on its own axis, which may or may not be synchronized with its orbit.
