What time results from calculating UY Scuti circumnavigation using the $909 R_{\odot}$ radius and $550$ MPH?

Answer

About $511$ years

The calculation yielding approximately $511$ years relies on integrating a more contemporary measurement for UY Scuti's size—the radius closer to $909 R_{\odot}$—with a sustained, theoretical cruising speed of $550$ MPH. Using the derived circumference for the $909 R_{\odot}$ star, which amounts to approximately $2.463$ billion miles, and dividing this distance by $550$ MPH results in over four million hours of travel. When converted to years using $8,766$ hours per standard year, the resulting projection is about $511$ years. This result demonstrates a significant time gap when compared to calculations based on the older, larger size estimates.
