To calculate the time it would take to travel around the circumference of UY Scuti at 50 mph, we first need to determine its circumference. UY Scuti has an estimated radius of about 1,700 times that of the Sun. The radius of the Sun is approximately 432,690 miles, so: Calculate the radius of UY Scuti: Radius of UY Scuti=1,700×432,690 miles≈735,573,000 miles Calculate the circumference using the formula C=2πr: C=2π×735,573,000 miles≈4,617,000,000 miles Calculate the time to travel this distance at 50 mph: Time=SpeedDistance​=50 mph4,617,000,000 miles​≈92,340,000 hours Convert hours to years: Years=24 hours/day×365 days/year92,340,000 hours​≈10,548 years So, it would take approximately 10,548 years to travel around the circumference of UY Scuti at a speed of 50 mph.
