The mass of neptune is about 1.03x10^23 metric tons. The mass of the sun is about 1.998x10^27 metric tons. ABout how many times the mass of Neptune is the mass of the sun? (give your answer in scientific notation) 

Mass of sun = K*(mass of neptune)
K=mass of sun/mass of neptune = 1.998x10^27/1.03x10^23 = 1.939*10^4
