Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it’s the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
What is the hottest sun color?
The hottest stars have temperatures of over 40,000 K, and the coolest stars have temperatures of about 2000 K.

What is hotter than the sun?
Yes, Carys; there are lots of places in our Universe where it’s much hotter than the Sun. Our Sun is a giant ball of gas that is 6000 degrees Celsius at the surface and millions of degrees in the centre. That is very hot! A kettle of boiling water is scalding hot and it’s “only” 100 degrees Celsius.
Which kind of star is hottest?
O stars are the hottest, with temperatures from about 20,000K up to more than 100,000K. These stars have few absorption lines, generally due to helium. These stars burn out in a few million years. B stars have temperatures between about 10,000 and 20,000K.
Is the sun hotter than a red giant?
A red giant is not very hot at its surface, but its core may reach 1 billion degrees Celsius (that’s 100 times hotter than the sun) (Dickin, 2005).
What color is the sun actually?
The color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination “white”. That is why we can see so many different colors in the natural world under the illumination of sunlight.
Is star hotter than Sun?
The sun’s surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit). That is why it is red — red stars are cooler than the sun, blue-white stars are hotter. Betelgeuse is, however, much bigger and brighter.
What is the hottest edible thing in the world?
Except this time, we really wouldn’t recommend you try to eat it. According to the Daily Post, the Dragon’s Breath chile, now the world’s spiciest pepper, clocks in at a hellish 2.48 million on the Scoville scale, dwarfing its nearest competitor, the Carolina Reaper, which comes in at 2.2 million.
What’s the spiciest thing on earth?
The Carolina Reaper took the Guinness World Record for the spiciest pepper in the world with 1.4 to 2.2 million Scovilles.
What is the coldest thing in the world?
The Boomerang Nebula is a young planetary nebula and the coldest object found in the Universe so far.
Which star is least hottest?
Spectral types are named with a letter. 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.
Which star is the hottest in the HR diagram?
The H-R Diagram
More massive main sequence stars are hotter, and are found at the top left of the strip. Less massive stars are cooler, and are found at the bottom right.
What is the hottest star in the sky?
Sirius, with its surface at a temperature of 18,000 degrees F, is so hot that it glows blue.
What is our sun’s life cycle?
The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.
How big will the sun get as a red giant?
Advertisement. When the Sun becomes a fully-fledged, full grown red giant (in some 7.59 billion years), it will reach its largest radius at 256 times its current size.
What if the sun was red?
Even if the Earth were to survive being consumed, its new proximity to the the intense heat of this red sun would scorch our planet and make it completely impossible for life to survive. However, astronomers have noted that as the sun expands, the orbit of the planet’s is likely to change as well.
