Which of the following is the correct sequence of the universal address from smallest to largest?

The correct sequence of the universal address from smallest to largest is indeed Earth, solar system, Milky Way galaxy, Universe. This sequence reflects the hierarchical structure of cosmic organization.

Starting with Earth, which is our home planet and represents the smallest unit in this context, we then move to the solar system, which includes our Earth along with the Sun and other celestial bodies such as other planets and moons that orbit the Sun. Moving up from the solar system, we reach the Milky Way galaxy, which contains billions of stars, including our Sun, and many planetary systems, including our solar system. Finally, the Universe is the largest scale, encompassing all galaxies, including the Milky Way, and all cosmic structures and materials.

This organization helps in conceptualizing the vastness of space and the relationships between different astronomical structures. Each step up the hierarchy represents a significant increase in scale, illustrating how various cosmic structures are nested within one another.
