Currently, there are only eight planets in our solar system, so there is no tenth planet. The tenth planet ever to be discovered (not counting Pluto as a planet) is a planet that orbits the star PSR B1257+12. It is about a thousand light years away from the sun.
The Tenth Planet was created in 2000.
Technically, yes. But, just a few years ago, scientists discovered a red, round, sphere-shaped hunk of rock that scientists believe may be a ninth planet(well, tenth planet if you count Pluto). It is still unclear if it really is another planet or not.

No. "Planet" Biyo is not a planet but an asteroid.
As of right now, there is no tenth planet in our solar system. There are only 8, as Pluto is no longer considered a planet.
