1.4 - Sunlike Starsystems

Sun From 150,000 observed stars, 42,000 similar to our sun and belong to spectral class G. This corresponds to a share of 28 % of all observed stars. The probability factor extrapolated for the occurrence of G stars in our galaxy is therefore:

Fs = 0.28 = 42,000:150,000 = 7:25

Related to all star systems A in our galaxy, the number Ns of the solar-like star systems results with:

1.4.1 Equation Ns = A · Fs


with the following factors:

A = (100 – 300)·109 Number of Suns in the Galaxy
Fs = 0.28 = 7:25 Probability factor for solar-like stars
   
Insert the factors into equation 1.4.1:
   
1.4.2 Theorem The number of star systems, with sun-like stars, in our galaxy is 28 to 84 billion.
