Goldilocks Zone
Lagrange Points

The Goldilocks Zone model computes and outputs the habitable zone for a planetery system on a 2D graph. The model overlays an annalus representing the habitale zone ontop of the model from task 2( see task 2 page for more details). A planet is considered in the goldilocks zone if the temperature due to the luminosity of the star is neither too hot nor too cold. The distance from the sun is calculated using the following formula:
$$Distance = \sqrt{\frac{StarLuminosity}{SolLuminosity}}$$
To find the lower bound of the annalus the distance is multiplied by 0.95 and to find the upper bound the distance is multiplied by 1.37. Naturally being withing the Goldilocks zone does not dictate whether or not the planet is habitable, rather dictates whether the temperature allows water to remain a liquid.
