What was the original shape of our solar system according to recent research?

According to recent scientific research, our solar system was originally shaped like a donut or doughnut during its formative years, rather than the flat disk we recognize today. This discovery comes from an in-depth study of iron meteorites originating from the outer reaches of the solar system. The findings have significant implications for understanding how planetary systems form throughout the universe and the developmental sequence of emerging planetary systems, potentially changing our fundamental understanding of cosmic formation processes.
