It depends on what you want to measure: their numbers, distance, mass, temperature, ...
You have it in reverse. Scientific notation is useful for measuring stars.
There is no such concept.

The exponent in scientific notation is a measure of the order of magnitude.
The scientific notation of the Andromeda Galaxy having at least 200,000,000,000 stars is 2 x 10^11 stars.
Numbers can be written in scientific notation. No conventional methods have been developed yet to apply the same notation to planets, stars, people, animals, cars, etc.
Scientists, Mathematicians and Engineers generally use scientific notation. In particular, those scientists and engineers who have to measure distances, weights or volumes of a very large or very small size. Astronomers, for example, may measure the distance of stars that are billions of billions of light years away. Wouldn't you rather write 4.9 * 1015 instead of 4,900,000,000,000,000?
Scientific notation is usually used to represent large numbers. For example - the number 123,400,000,000,000,000 can be represented in scientific notation as 1.234 x 1017. It's commonly used in astronomy when referring to the vast distances between stars etc.
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.
It is 8.9*10^-5 in scientific notation
With scientific notation, the kilogram does the job just fine.
It is "(scientific notation)".
