Is VV Cephei bigger than Uy scuti?
The currently (2020) accepted radius for UY Scuti is 755 solar radii, which means that the former record holder is in fact much smaller than VV Cephei.
Can you see VV Cephei?
VV Cephei is thousands of light-years away, but it’s so powerful that you can still see it with the unaided eye — if the sky is dark and moonless. And this kingly star has the perfect home, in the constellation Cepheus, the king.
What type of star is VV Cephei?
eclipsing binary star
VV Cephei is a eclipsing binary star in the Cepheus constellation. It is 5,000 light years from Earth. VV Cephei A is one of the largest known stars, being a red supergiant. Its diameter is 1,475 times that of the Sun.

Is Rigel a white dwarf?
Rigel is a blue supergiant that is the brightest star in the constellation Orion (the Hunter). Due to its measured size and brightness it is expected to end in a supernova one day. It also has two known companions, Rigel B and Rigel C.
Is Mu Cephei a carbon star?
Supernova. Mu Cephei is nearing death. It has begun to fuse helium into carbon, whereas a main sequence star fuses hydrogen into helium.

Will Rigel become a black hole?
Rigel’s large mass (18 times that of the sun) will mean Rigel will become a black hole. When the star runs out of fuel, it can no longer push gravity back, and the core will collapse. After the core collapses on itself, gravity, pushing against the star, will compact the core until it is very small.
Is Rigel or Betelgeuse bigger?
Betelgeuse is a red supergiant — the largest class of stars. Rigel is a blue supergiant. Like Betelgeuse, it is much bigger and heavier than the Sun. It’s surface is thousands of degrees hotter, however, so it shines blue-white.
How big is Cephei compared to the sun?
Mu Cephei is visually nearly 100,000 times brighter than the Sun, with an absolute visual magnitude of −7.6. It is also one of the largest known stars with a radius around or over 1,000 times that of the sun ( R ☉), and were it placed in the Sun’s position it would engulf the orbit of Mars and Jupiter.
