No, the Sun is not the hottest star in the universe. In fact, it’s not very hot at all compared to the population of stars in the Milky Way galaxy. When you look at stars in the night sky, you can guess their temperature based on their color. Any star that looks blue is burning much hotter than a red star.
What type of star in the galaxy is the hottest?
But the hottest known stars in the Universe are the blue hypergiant stars. These are stars with more than 100 times the mass of the Sun. One of the best known examples is Eta Carinae, located about 7,500 light-years from the Sun.
What is the hottest place in the Milky Way galaxy?
Using deep X-ray observations from ESA’s XMM-Newton Observatory, astronomers have discovered that Milky Way’s halo — a large cloud of ionized plasma surrounding the Galaxy — has a temperature of 10 million degrees Kelvin (about 18 million degrees Fahrenheit) — about 10 times hotter than previously estimated.
What is the hottest star discovered?
The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun.
What is the most hottest planet in the universe?

What’s the hottest place on earth?
Death Valley, California, USA The aptly named Furnace Creek currently holds the record for hottest air temperature ever recorded. The desert valley reached highs of 56.7C in the summer of 1913, which would apparently push the limits of human survival.
What is the coldest place in the Milky Way?
the Boomerang Nebula
The coldest place in the universe is in the Boomerang Nebula, a cloud of dust and gases 5,000 light years from Earth. It has a temperature of -272°C (-457.6°F). It is formed by the rapid expansion of gas and dust flowing away from its central ageing star.
What is the hottest thing in the Universe?
