The atomic model sometimes called the miniature solar system is the Bohr model.

This model, proposed by Niels Bohr in 1913, depicts the atom as a small, positively charged nucleus surrounded by electrons orbiting the nucleus in specific circular paths, much like planets orbiting the sun.

While it's a helpful visual analogy, it's important to remember that the Bohr model is a simplified representation and has limitations in explaining more complex atomic phenomena.
