What is the largest known sun?
star UY Scuti
In terms of sheer physical size, the star UY Scuti is considered the biggest known. It’s only 30 times the sun’s mass, but has a radius more than 1,700 greater than the sun.
What makes the Sun the biggest star?

Is the Sun a dwarf star?
The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.
