Star size comparison 2020 (updated)

Because new scientific discoveries have been made, I created an updated version of the video "Star size comparison 2020". As of August 2020, the largest known star in the universe is Stephenson 2-18. While previously the largest, UY Scuti is now ranked low as it was discovered to only have 755 Solar radii. Stephenson 2-18&radius is more than 2,000 times that of the Sun! Here are the biggest/largest stars included in this video: Arcturus, R136a1, Polaris, Aldebaran, Canopus, Rigel, Eta Carinae, Pistol Star, CW Leonis, Antares A, Betelgeuse, HV 2112, VY Canis Majoris, Westerlund 1-26, WOH G64, and Stephenson 2-18. Constellations: Bootes, Dorado, Ursa Minor, Taurus, Carina, Orion, Sagittarius, Leo, Scorpius, Tucana, Canis Major, Ara, Scutum Stephenson 2-18 is a red supergiant star within the open cluster Stephenson 2 located around 20,000 light years away from Earth in the constellation of Scutum. It is among the largest known stars and one of brightest red supergiants. It is estimated to be around 10 billion times bigger than the Sun. If placed at the center of the Solar System, it would engulf the orbit of Saturn. WOH G64 is another red supergiant star found in the Large Magellanic Cloud (LMC) satellite galaxy in the southern constellation of Dorado. Like Stephenson 2-18, it is one of the largest known stars in the universe, with a radius more than 1,500 times that of the Sun. Westerlund 1-26 is a red supergiant or red hypergiant within the outskirts of the Westerlund...
