Definition of a Goldilocks planet

A Goldilocks planet is a term used to describe a planet with conditions similar to those on Earth, specifically within the habitable zone of its star.

The term "Goldilocks planet" refers to a planet that falls within the habitable zone of its star, also known as the Goldilocks zone. This means that the planet is at a distance from its star where conditions are not too extreme, allowing for the presence of liquid water on its surface.

The habitable zone is crucial for the possibility of life on a planet, as liquid water is essential for life as we know it to survive. If a planet is too close to its star, water would evaporate due to the high temperature, while if it is too far away, water would freeze due to the low temperature.

The term "Goldilocks planet" draws its name from the story of Goldilocks and the Three Bears, where Goldilocks finds the porridge that is "just right" after trying three different bowls. Similarly, a Goldilocks planet is one that has the right conditions to support life as we know it.
