What kind of environment would an “ideal planet” have that supports vastly more life than Earth?

Kurzgesagt explored the conditions for Hestia, a fictional planet where life could thrive even more than on Earth.

The ideal star is a K-type main-sequence star, offering long-term stability and favorable light for biology.

Wide landmasses, dense atmosphere, shallow oceans, and active plate tectonics would boost biodiversity.

The concept helps explain which planetary traits may make a world more habitable and ecologically rich.
