What is a planet?

We all remember when Pluto was infamously demoted from being considered a planet. But, what even is a planet? And if the definition keeps changing, will there be more planets in the future?

In this episode of Huh? Science Explained, Evrim Yazgin discusses how the big reveal was followed by anger from those whose life had as one of its base facts that the solar system’s baby was our distant planetary equal. Now, Pluto had been slapped with the epithet “dwarf planet” and our solar system family shrank to eight planet siblings.

Since then, debate has raged over Pluto’s placement on the planetary pedestal.
