In a model of the solar system where the sun is represented as a loaf of bread, the size of everything else would be scaled down significantly to maintain proportion and relative distances. The exact size of each object would depend on the scale of the model, as it can vary depending on the purpose and design of the representation. However, generally speaking, everything else in the model, including the planets, moons, and other celestial bodies, would be much smaller compared to the size of the sun (loaf of bread) to accurately depict the vastness of the solar system.
In this model of the solar system with the sun represented as a loaf of bread, the sizes of the other celestial bodies would be scaled down compared to their actual sizes. The specific size ratio would depend on the scale used in the model. Generally, it is common to use a logarithmic scale to represent the vast differences in size between the sun and other planets. For example, if the sun is represented by a standard-sized loaf of bread, the sizes of the other planets, such as Mercury, Venus, Earth, Mars, etc., would be reduced proportionally to fit the scale of the model.
