The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. So the hottest stars in the Universe are going to be a blue star, and we know they're going to be massive. Similarly one may ask, what's the hottest star in space?
The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun.
Furthermore, what type of visible stars is the coolest? A red star is the coolest, but still is about 5,000° Fahrenheit! Our sun is yellowish-white and the surface is about 10,000° Fahrenheit. The hottest stars are blue, and can be as hot as 200,000,000° Fahrenheit at their core!
Also know, what star color is the hottest?
Blue stars
How hot is the hottest star in the galaxy?
Sirius, with its surface at a temperature of 18,000 degrees F, is so hot that it glows blue. What happens if a star is even hotter than blue Sirius?

Which is the most beautiful star?
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky. The name means "glowing" in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star. Is star hotter than Sun?
NO. The hottest stars have surface temperatures of 50,000 Kelvin degrees. The Sun surface is only 5800 Kelvin degrees, which means that there are hotter starts than the Sun. What is the biggest thing in the universe?
The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It's so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old. What is hottest thing in the universe?
A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That's more than 366,000 times hotter than the center of the Sun. What is the biggest star 2020?
UY Scuti. UY Scuti is the largest star in the universe and dwarfs all other stars. Astronomers working in Germany first discovered and identified the start in 1860 as part of their research at the Boon Observatory. What is biggest star in our galaxy?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun. What's the closest star to our sun?
Alpha Centauri A
What could cause a star to explode?
It's a balance of gravity pushing in on the star and heat and pressure pushing outward from the star's core. When a massive star runs out of fuel, it cools off. This causes the pressure to drop. The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode! What is a white star?
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains. What color is the coldest?
The temperature of a star refers to its surface and that is what determines its color. The lowest temperature stars are red while the hottest stars are blue. What does a purple star mean?
Purple star: 500 feedback points. Red star: 1,000 feedback points. Green star: 5,000 feedback points. Yellow shooting star: 10,000 feedback points. What color is the sun actually?
white
What color is a dying star?
These stars are in their mid life and are normal average stars. Orange or Red stars have used up most of their Hydrogen fuel and are approaching the end of their lives. Can a star turn into planet?
Yes, a star can turn into a planet, but this transformation only happens for a very particular type of star known as a brown dwarf. Some scientists do not consider brown dwarfs to be true stars because they do not have enough mass to ignite the nuclear fusion of ordinary hydrogen. Which star is the coldest?
It is true as a Penn State University astronomer using NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescopes has discovered a "brown dwarf" star that appears to be the coldest of its kind. The star has been named WISE J085510. Are there purple stars?
Although you can spot many colors of stars in the night sky, purple and green stars aren't seen because of the way humans perceive visible light. Stars are a multicolored bunch. There are red giants on the verge of explosions. Are all stars actually white?
The color of a star depends on its surface temperature. Our Sun's surface temperature is about 6,000 Kelvin. Although it looks yellow from here on Earth, the light of the Sun would actually look very white from space. The coolest stars in the Universe are the red dwarf stars. Is the sun black?
The Sun, with an effective temperature of approximately 5800 K, is an approximate black body with an emission spectrum peaked in the central, yellow-green part of the visible spectrum, but with significant power in the ultraviolet as well. How long do stars live for?
about 10 billion years
What's the difference between a star and a sun?
The Sun is a perfectly ordinary star -- a great, glowing ball of gas. In that case, the answer is "No, not quite." Planets are very common around other stars, orbiting as many as 30 percent of stars similar to the Sun. However, there are plenty of stars for which we have no evidence of orbiting planets. What is the coldest planet in the universe?
Uranus
What are the 7 types of stars?
There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M. O and B stars are uncommon but very bright; M stars are common but dim.. Why are blue stars hotter than red stars?
Well, to answer this, a shorter wavelength means greater energy. This is important because if you look at the spectrum, blue photons have more eery than red photons so the blue star generates more energy and more heat than the red. To answer simply, the red stars are lower in temperature than the blue stars. What star has the coolest surface temperature?
M stars are the coldest stars and O stars are the hottest. The full system contains other types that are hard to find: W, R, N, and S. The closest star to the Earth, the sun, is a class G star. Why do stars look so small?
Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). But the stars are very, very far away from our solar system so they appear to be very tiny to us, even though up close they are large. They reflect the light of the sun in the same way our moon reflects sunlight. Are all visible stars in our galaxy?
All the stars we see in the night sky are in our own Milky Way Galaxy. Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area. It is very difficult to count the number of stars in the Milky Way from our position inside the galaxy. How hot is a lightning bolt?
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun). Is Sirius hotter than Sun?
Sirius is classified by astronomers as an “A” type star. That means it's a much hotter star than our sun; its surface temperature is about 17,000 degrees Fahrenheit (9,400 Celsius) in contrast to our sun's 10,000 degrees F (5,500 C). What is the brightest thing ever?
The Brightest Quasar of the Early Universe Shines with the Light of 600 Trillion Suns. Scientists have discovered the energetic core of a distant galaxy that shatters the record for the brightest object in the early universe, blazing with the light equivalent to 600 trillion suns. How hot is WR 102?
210,000 K
What star has the most energy?
The greater the mass of a main sequence star, the higher its core temperature and the greater the rate of its hydrogen fusion. Higher-mass stars therefore produce more energy and are thus more luminous than lower mass ones.
