Spectral class is the categorization of stars by temperature and size, mostly the former. Spectral class B is very hot. In descending order (hottest to coolest) the spectral classes are O,B,A,F,G,K,M. You can see that B is very near the top.

Is earth a hot or cold planet?
well you can't really class it as a hot or cold planet yes the desert is hot but not compared to the sun the north pole is cold but not as cold compared to Pluto
Will astronaut feel hot in their spacesuits?
No the suits are regulated to protect them from the freezing cold of space.
Is there radiation in space storms?
Well actually there is radiation. Because space is so cold that when the storm forms they both make radiation. Just like hot air and cold air making a tornado.
Are meteoroids hot?
That depends. Meteoroids are pretty cold when they float around in space. When they enter our atmosphere, they get super hot and usually burn up in the thermospere.
What will happen to steel railroad tracks on a hot day if they were laid out during a cold day without clearance or gap?
When metals become cold, they contract and take less space, but when a metal gets hot, it expands and it will need more space. So, in this case the metal tracks took less space when fitted without gaps on the cold day, but on the hot day the metals will need more space and therefore will push outwards. The tracks will become buckled, and when the train comes, it will go off track.

What numbers fill the spaces 150 SPACE 84 SPACE 42 SPACE 30 and if possible what is the formula?
"what is the wether like in space? always hot? manley cold? both?" I assume this was posted as a joke, because it was posted as an answer not a question, but always cold. In a way cold does't actually exist, it is just an absence of heat. If there is no gases, in space to be hot, then there is an absence heat, or cold.
During a class discussion about hot and cold weather emergencies you remind the class that the human body depends upon what to cool itself in hot environments?

Why is outer space cold?
because the sun faces the earth while the earth is being hot Outer space is neither hot nor cold. Temperature measures the energy of atomic particles. Sense there is no atomic particles in the vacuum of outer space there is no temperature.
How hot is Matar?
Eta Pegasi (Matar) is a star in the constellation Pegasus.It has a spectral class of G2 (The same as our Sun) so has a temperature range of between 5,200 --> 6,000 Kbuttckeecks
Is space hot or cold?
Space itself is neither hot nor cold. It is the matter within it that varies in temperature. The temperate of this matter is dependant upon many variables, such as its distance from other planetary bodies, thermal properties e.t.c.
How are you sure how hot the sun is if it is too hot to go near?
We compare its spectral data to that of earth.
How hot is Rucha?
Delta Cassiopeiae (Ksora and Ruchbah) is a star in the constellation Cassiopeia.It has a spectral class of A5 so it's colour will be white and have a temperature of between 7,500--10,000 Kelvin
How hot is Hadar?
Beta Centauri (Hadar and Agena) is the second brightest star in the constellation Centaurus.It has a spectral class of B1 so it will have a temperature of the upper limit of 10,000 -> 33,000 Kelvin.
Will astronaut feel hot in their spacesuits?
No the suits are regulated to protect them from the freezing cold of space.
Is the blck hole hot or cold?
my guess is that a black hole would be niether because there is no atmoshere in space, although, it could be cold. i KNOW its not hot. Zachary mcalpin (13)
