SOLAR SYSTEM

Detailed explanation-1: -Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped.

Detailed explanation-2: -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.

Detailed explanation-3: -Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.

Detailed explanation-4: -The colors of stars from hottest to coldest are blue, blue-white, yellow, orange, and red. The colors of the stars indicate their surface temperatures. There are five star colors: blue, white, yellow, orange, and red.

Detailed explanation-5: -Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it’s going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky.
