Question

At which distance from the dot should earth be placed in the model

Answer 1

To provide you with a specific answer, I would need to know more about the context of the model you're referring to. For instance, are you talking about a model of the solar system, a scale model for a classroom, or a conceptual model for educational purposes?

In a scale model of the solar system, distances can vary widely depending on the scale used. For example, in a common scale where the Earth is represented by a small dot (like a marble), other distances can be expressed in terms of that scale.

If you specify the type of model or scale you are working with, I can give you more detailed guidance!
