The star is nearly 2,000 times bigger than the Sun, lighter than water

The Sun is just like a dust particle when compared to the largest star in the universe.

In terms of radius, the biggest star today is UY Scuti , a giant red object glowing in the constellation Scutum. Located 9,500 light-years from Earth, UY Scuti consists of hydrogen, helium and heavier elements similar to the Sun's chemical composition. However, this star has a diameter of 1,708 times that of the Sun.

According to Epoch Times, UY Scuti 's diameter is nearly 1.2 billion km, while the circumference length is 7.5 billion km. A person needs 950 years to fly around the star with commercial aircraft. Even the light takes 6 hours and 55 minutes to move around UY Scuti. If replacing the Sun, UY Scuti's surface will be in the orbit of Jupiter and Saturn and Earth will be swallowed by the star.

With a giant size and weight of 20-40 times the Sun, UY Scuti has a gas density of 7 × 10⁻⁶ kg / m³ , which is a billion times less dense than water. In theory, if possible in a large enough water tank, the planet will emerge.

UY Scuti can own the largest size of the universe but not at the top of the volume. The mass champion in the universe is the star R136a1 , located in the Large Magellanic Cloud, 165,000 light-years from Earth.

R136a1 also has an atmosphere consisting of hydrogen, helium and heavier elements. Its radius is 35 times greater than the Sun but has 265 times more mass. According to scientists, this star has lost mass by 55 Suns in 1.5 million years of existence. R136a1 is less stable star type. It has a blue atmosphere and emits super strong solar winds, moving at 2,600 km / s.
