Which stars will die the quickest?
Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.
Which color star is hottest?
The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red. A color index of a star is the difference in the magnitudes measured at any two wavelengths and is one way that astronomers measure and express the temperature of stars.
What object is the brightest as seen on Earth?

What star in the sky is flashing?
Sirius appears to twinkle or shimmer more than other stars due to some very simple reasons. It is very bright, which can amplify atmospheric effects. It is also very low down in the atmosphere as a result of being viewed in the northern hemisphere.
Where is the North Star?
Polaris is located in the constellation of Ursa Minor, the Little Bear. It sometimes also goes by the name “Stella Polaris.” The seven stars from which we derive a bear are also known as the Little Dipper.
