YouTube Description
as posted by the channelYes, the question of what makes a planet a "planet" is back in the news after a team of planetary scientists published a new paper challenging the status quo and arguing that Pluto should be a planet again. You may have thought this issue was settled back in 2006 but many problems exist with the current definition. We explain what's wrong with the current version, what this new paper proposes instead and the consequences of the change if it were to be accepted.
