The color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.
Moreover, what is the fastest known entity in our universe True or false?
Light is the fastest-known entity in our universe.
Also to know is, which of the following happens during the main sequence stage of a star’s life quizlet?
Which of the following happens during the main-sequence stage of a star’s life? It cycles, appearing brighter and dimmer in turns.
Which factor affects the color of the star?
For instance, the color of a star – which varies from bluish-white and yellow to orange and red – is primarily due to its composition and effective temperature. And at all times, stars emit light which is a combination of several different wavelengths. On top of that, the color of a star can change over time.

What is the star life cycle?
A star’s life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star’s mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born.
What are the 5 stages of a star?
All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.

How is a star born step by step?
A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.
