Is it possible for two planets to be in the same orbit path?

Even if the orbit could somehow be stable they wouldn't actually be *planets* by the latest definition. To be defined as planet a body should: orbit a star, be heavy enough to become round by it's own gravity and **dominate it's own orbit and clear it up**, this is also why Pluto is no longer defined as a planet.
