At dusk the sky looks blue behind the stars. In fact the sky is within 100 km while the stars are light-years away.
The hottest star is called O-type blue stars. They have surface temperatures of around 30,000-60,000 degrees Celsius.
Orion's Belt consists of three bright stars called Alnitak, Alnilam, and Mintaka. These are classified as blue supergiant stars, which are massive, hot stars that emit a blue-white light.
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
Small cool stars, such as red dwarfs, are typically red or orange in color. This is because their surface temperatures are relatively low, causing them to emit more red and orange light compared to other colors.
