What is a giant supergiant star?
What is a giant supergiant star?
supergiant star, any star of very great intrinsic luminosity and relatively enormous size, typically several magnitudes brighter than a giant star and several times greater in diameter.
What is the difference between giant and super giant stars?
Giant stars have radii up to a few hundred times the Sun and luminosities between 10 and a few thousand times that of the Sun. Stars still more luminous than giants are referred to as supergiants and hypergiants.
What is the largest super giant star?
The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun.
What do supergiants do?
The Super Giant is a melee unit with a very high amount of hitpoints for its housing space. Its Wall Buster ability allows it to deal extra damage (5x?) to Walls, but despite this, it does not preferentially target Walls (see below).
Do supergiants have planets?
It is known that around supergiant stars planet exist. A planet in the habitable zone is, most likely, one that was in the Kuiper Belt when the star was on the main sequence. Because this, there is a high chance that the planet will be mostly made of ices. As they melt, it will become an Oceanic Planet.
What are giants and supergiants?
Large Surface Areas That is why they are called giants and supergiants: they are much larger stars than the corresponding main sequence stars. For example, a giant star like Arcturus is almost twenty times larger than the Sun, and the supergiant star Antares is more than 300 times larger than the Sun.
Do blue giants exist?
Blue Giants Are Very Hot That’s about 172 times hotter than the Earth, but still quite cool compared to blue supergiants. These stars are some of the hottest and can have surface temperatures in excess of 40,000K – about four times hotter than the Sun.
Is Sirius a supergiant?
Sirius A is about twice as massive as the Sun ( M ☉) and has an absolute visual magnitude of +1.42. It is 25 times as luminous as the Sun, but has a significantly lower luminosity than other bright stars such as Canopus or Rigel….Sirius.

Is UY Scuti or Stephenson 2 18 bigger?
Stephenson 2-18 compared with UY Scuti WOH G64 has an estimated radius between 1,540 and 1,730 solar radii, which is considerably smaller than both St2-18 and the current runner-up, MY Cephei (2,061 R☉).
What would happen if UY Scuti exploded?
So the force of 100 stars exploding would obliterate everything nearby. Even if Earth was far enough away to survive the blast, without the star, there would be no heat and no light, and life could not survive on Earth without them.
Is Sun a supergiant?
The Sun is medium-sized. It burns its hydrogen fuel fairly slowly, so it can keep shining for 10 billion years.
