Which vehicle's corrected cruising velocity resulted in a projected circumnavigation time of approximately $867$ years for the larger UY Scuti circumference?

Answer

Faster Business Jet (Corrected G650) ($ ext{\sim } 610$ MPH)

The projection of approximately $867$ years for circumnavigating the large $4.634$ billion mile circumference is specifically tied to the corrected cruising velocity of the Gulfstream G650 business jet. While an initial speed estimate for the G650 was cited at $904$ MPH, a correction was applied, settling on a more typical cruising velocity around $610$ MPH. Traveling at this moderate jet speed over the vast distance yielded the longest terrestrial flight time estimate among the comparisons provided for that specific larger circumference, highlighting the impact of vehicle speed on travel duration.
