Distance in space is measured in 'light years' or in 'scientific notation'
1.58936877 × 1017
Converted to kilometers gives you large numbers, which are best expressed in scientific notation. A light-year is about 9.5 x 1012 kilometers. Multiply that by the number of light-years.
The age of the Earth is approximately 4.54 billion years, which can be represented in scientific notation as 4.54 x 10^9 years.
The Milky Way galaxy is approximately 100,000 light-years in diameter. In scientific notation, this would be written as 1 x 10^5 light-years. Using the nearest prefix, we can express this as 100 kilo-light-years.
