An Unhappy Pluto

Let's say Pluto is unhappy at being demoted, feeling sad being outcast from the planetary family. What if it changes its mind and its own orbit, and decides to head towards Earth. Can Earth get out of its way or alter its own path?

So, Pluto is no longer a planet. But do you think Pluto really cares? What if there is life on Pluto after all, and the Plutonians have stopped considering Earth as a planet centuries ago. What if they believe that the earth is nothing but an odd ball, precariously tilted on its own axis, with its people constantly fighting among themselves, unlike the Plutonians.
