What are the hottest stars in order?
The spectral sequence of stars runs OBAFGKM.
- O stars are the hottest, with temperatures from about 20,000K up to more than 100,000K. …
- B stars have temperatures between about 10,000 and 20,000K. …
- A stars have strong absorption lines of Hydrogen. …
- F stars are slightly hotter than the Sun.
What are the 7 spectral classes in order from hottest to coolest?
Most stars are grouped into a small number of spectral types. The Henry Draper Catalogue and the Bright Star Catalogue list spectral types from the hottest to the coolest stars (see stellar classification). These types are designated, in order of decreasing temperature, by the letters O, B, A, F, G, K, and M.
Which one is the correct order from hottest to coldest star?
The seven main types are M, K, G, F, A, B and O. 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.
What color is the hottest flame?
Blue flames Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you'll see in most fires. It's interesting to note that, despite the common use of blue as a cold colour, and red as a hot colour – as they are on taps, for instance – it's the opposite for fire.
What is the hottest known star?
The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun. Like Baskin-Robbins, Wolf-Rayet stars come in a variety of flavors.
What are the 5 colors of stars?
The stars show a multitude of colors, including red, orange, yellow, white, and blue. As we have seen, stars are not all the same color because they do not all have identical temperatures.
What is the order of star colors with decreasing temperature?
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.. An easy mnemonic for remembering these is: “Oh be a fine guy/girl, kiss me.”
What are the 7 classes of stars?
The stars are divided into 7 classes designated by the letters O, B, A, F, G, K, and M; the hottest stars (O and B) are blue-white in color, while the coolest (M) are red.
What color is the hottest Sun?
The hottest stars are blue, with temperatures around 25,000 K. Red is the color of the coldest stars, which have surface temperatures of approximately 3,000 K….The 5 Colors of Stars.
| Star Color | Orange |
|---|---|
| Class | K |
| Approx. Temperature | 4,000 K |

What are the colors of fire in order?
The color inside the flame becomes yellow, orange, and finally red. The further you reach from the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C).
Is green fire the hottest?
Violet is the hottest color fire. It can burn at around 3,000 degrees Fahrenheit (1,650 degrees Celsius). That's hot enough to burn almost any material and a violet flame is often seen in welding and cutting operations for this reason.
Why blue star is the hottest?
The color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.
What is the hottest Sun color?
blue As a star's temperature increases, as a result of there being more gas in the star – and hence more fuel to burn – it becomes hotter. Its colour changes from orange, through yellow, to white. The hottest stars are blue, with temperatures up to 40,000ºC.
Why are blue stars the hottest?
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 is the hottest color Sun?
The hottest stars are blue, with temperatures around 25,000 K. Red is the color of the coldest stars, which have surface temperatures of approximately 3,000 K….The 5 Colors of Stars.
| Star Color | Yellow |
|---|---|
| Class | G |
| Approx. Temperature | 6,000 K |
| Examples | Proxima, the Sun |

Which is hotter O or B?
Most stars are currently classified under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type).
What is the hottest color of fire?
Blue flames Blue flames are the hottest, followed by white. After that, yellow, orange and red are the common colours you'll see in most fires. It's interesting to note that, despite the common use of blue as a cold colour, and red as a hot colour – as they are on taps, for instance – it's the opposite for fire.
Is white the hottest fire?
While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames. When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.
How hot is purple fire?
The color of the flames is apart of temperature affected also by the type of fuel used (i.e. the material being burned) as some chemicals present in the material can taint flames by various colors. Blue-violet (purple) flames are one of the hottest visible parts of fire at more than 1400°C (2552°F).
Is black fire Possible?
Flames emits light and heat, so it seems impossible to make black fire. However, you actually can make black fire by controlling the wavelengths of absorbed and emitted light.
How hot is an orange star?

Which star is hotter red or blue?
The fact that stars come in different colours is not a mere curiosity. The colour provides a fundamental piece of data in stellar astrophysics—the surface temperature of the star. The hottest stars are blue and the coldest are red, contrary to the use of colours in art and in our daily experience.
Is a blue star hotter than the Sun?
The Sun surface is only 5800 Kelvin degrees, which means that there are hotter starts than the Sun. Answer 3: The sun is an "averagely hot" star in the universe. There are many stars that are hotter than the sun — for instance, stars that burn blue are hotter than our sun!
Is blue hotter than red?
When we talk about blue light being cool and red light being warm, we are referring to something very different from color temperature. We are using these colors to describe our perceptions or to convey moods. Counterintuitively, blue-hot is actually hotter than red-hot.
What does OH a fine girl kiss me mean?
Every student in introductory astronomy learns the mnemonic “Oh Be a Fine Girl/Guy, Kiss Me”, which is a way to remember the spectral classification of stars. Here's how it works: the color of a star is determined by its temperature, as I outlined previously.
What is the weakest fire color?
Fire temperature While weaker, red flames can still range from 525°C to 1000°C. The more faint the colour, the lower the temperature. A more vibrant red, something closer to orange, will hit the higher end of the scale measuring nearer the 1,000°C mark. Orange flames range from around 1100°C to 1200°C.
