The hottest stars are the blue stars, the blue hypergiants in particular. One example is "R136a1", which is a blue hypergiant that has estimated surface temperatures of over 40,000 Kelvin (well over 70,000 F). Our Suns effective temperature is around 5,700K for comparison.
Stars can range from blue to red depending on temperature and mass, with yellow stars in the middle and white stars on the back end of the spectrum.
Almost all stars fall in a mass range of
lower limit because the particles have zero energy. there is no upper limit because particles can move as fast as they like. There is an upper limit on temperature, called "Planck Temperature". It is approximately 1.42e32 Kelvin! This temperature is the maximum temperature something can attain, with the physics we understand.
The HR diagram has the star's temperature along the horizontal axis and the absolute magnitude (brightness) along the vertical axis. Each star is represented by a single dot. Higher temperature is usually associated with more brightness so many stars lie on or near a line on the diagram called the Main Sequence. Red giant stars are found on the upper right hand quarter because they are relatively cool but still very bright.

Capella is in fact a binary star. The two stars are both G type stars and thus will have a temperature range of between 5,200 and 6,000 oK

Cygnus is a constellation comprising 84 stars which appear in the Bayer Flamsteed lists. They are not all the same and cover a wide range of temperatures.
You realize that stars are "Suns", yes? And you know the Sun is about 6000 degrees Celsius, at its surface? So in short, no, stars are very hot. Comment: There is a big temperature range amongst stars, but even the coolest stars can't really be described as cold.
The highest temperature minus the lowest temperature is the temperature range. The temperature range is how many degrees is in between the highest and lowest temperatures.
The hottest stars are the blue stars, the blue hypergiants in particular. One example is "R136a1", which is a blue hypergiant that has estimated surface temperatures of over 40,000 Kelvin (well over 70,000 F). Our Suns effective temperature is around 5,700K for comparison.
The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.
no, stars temperature are diffrent according to their color. for instance, blue white stars are hotter than red stars
the color of stars with the lowest surface temperature is red
Other yellow-white stars like our sun do exist. The color of a star depends on its temperature. The coolest stars are red while the hottest are blue. Our sun falls in the middle of this range.
