Why did Pluto stop being a planet?

Does Pluto have a moon?

Why does Mercury have no moon?
Mercury and Venus
Neither of them has a moon. Because Mercury is so close to the Sun and its gravity, it wouldn't be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the Sun and eventually get pulled into it.
Can dwarf planets have moons?
Most of the major planets – all except Mercury and Venus – have moons. Pluto and some other dwarf planets, as well as many asteroids, also have small moons.
Can a human survive on Pluto?
No. The average surface temperature there is -229 C (that's -380 F for us in the United States), and there's no breathable oxygen (it's all frozen), and nothing to eat or any way to produce something to eat. Long-term survival at or near Pluto would require technology that hasn't been invented yet.
