Matter exists in millions of different forms on this planet, and even if you intended to say phases, there are also more than 3 phases on this planet (the reason fire glows, is because it contains a highly ionized form of matter known as plasma, which is a separate phase from the more common solid, liquid, and gas phases).
Anyway, the more variety in the forms of matter, the more we can do with matter.
Matter can exist in many forms.
Planet exist because the amount of matter is not large enough or not made of superheated hydrogen to become a star.
Light energy can exist independently of matter. *Studyisland
Temperature causes the matter to exist in three different states. They are Solid, Liqid and Gas. If temperature is increased matter changes into gas and if temperature is decreased it changes into solid.
Yes. Neptune is the outermost planet in the solar system.
Mermaids do not really exist. They exist only in our imaginations. Though there may be "mermaids" at the unexplored reaches of our Earth (or any other planet for that matter), there are no real mermaids that we know of.
States of matter are: - solid - liquid - gas - plasma - Bose-Einstein condensate - dark matter - fermionic condenste - strange matter etc.

No. Such a planet could not exist.
Planet X does not exist - it was a hypothetical planet.
