The masses of four planets in a solar system outside the milky way are given below. mass of planet a: 5.97 × 10 24 kg; mass of planet b: 3.30 × 10 23 kg; mass of planet c: 1.89 × 10 27 kg; mass of planet d: 4.87 × 10 24 kg what is the order of these planets from least to greatest mass? planet c; planet b; planet d; planet a planet c; planet a; planet d; planet b planet b; planet d; planet a; planet c planet a; planet d; planet b; planet c\

For this case, the first thing we will do is write a table:
 Mass of Planet A: 5.97 × 10 24 kg;
 Mass of Planet B: 3.30 × 10 23 kg;
 Mass of Planet C: 1.89 × 10 27 kg;
 Mass of Planet D: 4.87 × 10 24 kg
 We observe that according to the scientific notation we have:
 3.30 × 10 23 kg <4.87 × 10 24 kg <5.97 × 10 24 kg <1.89 × 10 27 kg
 Therefore the order of the planets from lowest to highest mass is:
 Planet B, Planet D, Planet A, Planet C
  
 Planet B, Planet D, Planet A, Planet C
