What kind of factors go into a calculation like this?

The habitable zone, also known as the “Goldilocks zone,” is the region around a star where temperatures are just right for liquid water to exist on the surface of a planet. This is considered an important factor in the potential for life to exist on a planet.
Scientists calculate the habitable zone of a solar system by considering the distance of a planet from its star and the amount of energy that the star emits. They use models that take into account factors such as the planet’s orbit, its atmosphere, and its ability to retain heat from its star in order to estimate the temperature on the planet’s surface.
In our solar system, the habitable zone is considered to be in the region between Venus and Mars. Venus is too close to the Sun, and its surface is too hot for liquid water to exist, while Mars is too far away, and its surface is too cold. Earth is located in the habitable zone and has temperatures that allow for liquid water to exist.
To calculate the habitable zone in other solar systems, scientists use telescopes to observe the stars and planets in those systems. They use the data they gather to estimate the distance of the planets from their stars and the amount of energy that the stars emit. They then use this information to estimate the temperature on the planets’ surfaces and determine if they are in the habitable zone.
It’s worth mentioning that the concept of habitable zone is just an estimation, and it’s not definitive. Even if a planet is located within a habitable zone, it doesn’t mean that it’s inhabited. There might be other factors like the atmosphere, geology and the magnetic field that can affect the habitability of a planet.
