Comparing The Life And Lifespan Of A Star

When we look up into the sky we think that we are living the present, but in all reality we living and looking at the past. The light that we see from stars takes time to reach earth, this means that we can be looking at the light of a star that was produced four years ago; this is a result of the distance between earth and the star. The life and death span of a star depends on the mass of the star. Based on the distance of the sun from the earth and the amount of energy that the sun produces, the living things on earth have approximately 10 billion years of life left ( name of author).
Mostly all stars have the same life cycle, the only thing that distinguishes the end result of the stars is the amount of mass that each star contains. All stars are formed the same way, they are all formed in clouds of gas and dust (name of author). Throughout the lifespan of a start ,the star would over go through various changes. Changes of a star can include loss of heat, expansion and even the change of color.For example a star with a small amount of mass will …show more content…
The nuclear reactions at the core of the star provide the star with sufficient energy to shine for many years ( name of author ). The amount of time that it takes for a star's light to reach earth depends on the location of the star. Usually the farther away the star the more dim its light would be and the closer the start results in a brighter and stronger light. For example the sun is 92.96 million miles from earth and its light travels 186,000 miles per second ( name of author). As a result of the speed of its light and its distance it takes a total of 8 minutes for the sunlight to reach earth. This means that if the sun were to suddenly disappear it would take people on earth 8 minutes to realize that there is no longer a sun ( name of author). Another example would be the distance of the second closest star ( name of star
