What is hotter the sun or Mars?
The sun!! It's a STAR!!!
Which is bigger a neutron star or a subgiant star?
Considering a neutron star is about the size of a city, a subgiant is way bigger.
Is a blue-white star hotter than the sun?
yes
What is hotter Jupiter or Saturn?
Jupiter is bigger than Saturn
Which star is hotter in an eclipsing binary system?
Generally the main star as this will have the most mass. However, temperature is not necessarily based on mass, so a secondary unit, could well be hotter but less massive.
Which star is hotter betelgeuse or spica?
spica is hotter. even though btelgeuse is bigger it is not as hot as spica
Are super giants stars the hottest stars?
The bigger the star the hotter it is and the shorter the time it exists for.
Why is the sun hotter than venus?
because the sun takes the energy from stars and the sun is bigger and its a star
Is the sun or a blue star hotter?
The blue star is hotter
Which star is hotter red or orange?
An orange star is hotter than a red star.
Are Red super giants hotter than the Sun Why?
Because the sun is a star, and red super giants are bigger stars.
What is hotter a black star or a white star?
Technically Blue stars are hotter but from your options, white stars are hotter.
Why will a star get bigger?
It will get bigger because it gets hotter. In a star, gravity is trying to squash it together (make it smaller), however as the core of the star is squashed smaller it gets hotter and the nuclear reactions going on in the core begin to happen faster. This generates more heat and the pressure form this heat and light (energy) pushes the outer layers of the stare further away form the center of the star - the star inflates (gets bigger). Stars get bigger when they leave the main sequence (run out of hydrogen to fuse in their cores) and their cores shrink and get hot enough to fuse helium and other heavier elements. The other thing that happen as the star gets bigger and hotter is that it gets redder because although it is giving off more energy, the surface area over which this energy is being emitted has increased too and this mean each bit of the surface is no as hot as it was before it inflated.
Is a red jaint hotter than a red star?
no the red jiant is hotter
Is a blue star hotter than a red giant?
blue stars are hotter
What are the factors that make one star appear brighter than another star?
The size of the star, because the smaller the star the hotter it is because of nuclear fusion. So the hotter the brighter.
Is an orange star hotter then a yellow star?
The temperature of a yellow star's photo sphere is hotter than that of and orange star. However the total energy output of an orange star may be greater than that of a yellow star.
