Stars in the milky way in scientific notation?

Answer 1

The answer has to be estimated; for many reasons no one can ever know the exact numbers, whatever that might mean in this context. Estimates of the number of galaxies in the universe range from about 170 billion to one trillion. One trillion is one thousand millions. Estimates of the number of stars range from around 70 sextillion to 300 sextillion. Seventy sextillion is 7 followed by 22 zeros. 300 sextillion is 3 followed by 23 zeros. Some estimate as high as 10 to the power 24, which is one followed by 24 zeros. You might think that 22, 23 and 24 are small numbers here, until you begin to consider that every single one of them represents a power of ten. The number is far beyond anything that any human mind can grasp on anything close to a practical level.

Answer 2

There are about 2e11 stars in the Milky Way galaxy. As there are about 1e11 galaxies in the universe, perhaps averaging 1e11 stars per each, that makes the number of stars in the universe roughly 1e22.

For e (exponent) you could write x10^
Our Milky Way i s a GALAXY. These are many billions of stars bound together in a plane. Galaxy's are not 3D. Depending on from which direction you view a galaxy it can look like a pancake, or it can just look like a line or band from left to right. We see our Milky way as a band of stars because we are viewing it from within, thus, viewing it as a line or band.

Answer 3

Estimates have tended to range between 300 billion to 400 billion.

Answer 4

The number of stars in the Milky Way is estimated to be around 200 billion, which can be written in scientific notation as 2 x 10^11 stars.

Answer 5

Approximately 200 --> 400 x 109 stars
