If we were able to view the Milky Way Galaxy from a perspective outside of it, it would indeed appear as a spiral galaxy. The Milky Way is a barred spiral galaxy, meaning it has a central bar-like structure with spiral arms extending from it. The spiral arms consist of stars, gas, and dust that form a characteristic spiral pattern.
However, it's important to note that Earth is just one of billions of stars within the Milky Way. While it holds significance for us as the planet we inhabit, it would not appear as a distinct "white dot" at the center of the galaxy when viewed from afar. Instead, it would be just one of the many stars that make up the overall structure of the galaxy.
In general, when observing spiral galaxies from a distance, the central region may appear more concentrated due to the presence of a bulge or a brighter central nucleus, but individual stars or planets within the galaxy would not be discernible as distinct points of light at such a large scale.
