How many times larger is UY Scuti’s estimated radius compared to the Sun’s radius ($R_{\odot}$)?

Answer

Around 1,700 times

The fundamental comparison used to comprehend the scale of UY Scuti relies on its radius relative to our Sun. Scientific reports estimate that the radius of UY Scuti is about 1,700 times the radius of the Sun. This factor is crucial for deriving subsequent physical measurements, such as its diameter and circumference. Multiplying the Sun's known radius (approximately 695,700 kilometers) by this factor of 1,700 yields the colossal linear dimensions associated with this stellar object, positioning it as one of the largest known stars.
