When talking about the number of miles to other stars, it is best to use scientific notation. Example: 2.38 x 1014 looks better than 238000000000000.
Some numbers are so huge (like the mass of the sun=1.98892 × 1030 kilograms) that writing a number with thirty or so digits is difficult to manage. There are some numbers so small that we have the same problem (the mass of an electron is 9.10938188 × 10-31 kilograms). Scientific notation is actually clearer and simpler to write in these two cases.Scientific notation is important IF you are going to understand some things in the universe. Some authors use Scientific notation to discuss the topics they are writing about. You will not understand what those authors are talking about without understanding Scientific notation.
The idea is to show very large numbers, or very small numbers (close to zero) in a concise notation. If you write down the mass of the Sun in kilograms, it is very cumbersome; also, you have to count the digits to compare with some other number (such as the mass of another star); with scientific notation, you can immediately compare two such numbers.

Therefore, the decimal number 0.000487 written in scientific notation is 4.87 × 10-4 and it has 3 significant figures. Here are some more examples of decimal to ...
Some examples of scientific notation:6,300,000 is 6.3 x 106. .00000000000000524747474 is 5.247 x 10-16 (rounded to 4 significant figures)0.0000000056, we write 5.6 x 10-9953 in scientific notation is 9.53 x 10^2

All areas. Scientific notation is useful whenever you have very small or very large numbers, and these appear in some aspect of every branch of science.

Scientific Notation will be used at some point especially if you are a scientist, or doctor. It is used to compute very large or very small numbers.
It is because some of the numbers that they deal with are very large or very small.
Scientific notation is a short hand way of expressing numbers that are very large or very small such as 10,000,000 = 1.0*107 or 0.0000001 = 1.0*10-7
Because it deals in some very large and very small numbers.
