PHYSICAL PROPERTIES (Earth = e)…
Using the center-of-mass equations or the Center of Mass Calculator (under
Binary-Star Basics, above), you will investigate a specific binary-star system.
Assume that Star 1 has
m₁ = 3.4 solar masses, Star 2 has m₂ = 1.4 solar masses, and the total
separation of the two (R) is 52 AU. (One AU is Earth's average distance from the
Sun.)
(a)What is the distance, d₁, (in AU) from Star 1 to the center of mass?
AU
(b)What is the distance, d2, (in AU) from Star 2 to the center of mass?
AU
given:
a (distance to center of galaxy in AU) = 1,717,914,439 AU
P (suns orbital period in years) = 203,782,828.3 years
M (mass of milky way galaxy in solar masses) = 1.22 x 10^11 Msun
Question:
Assume the Milky Way Galaxy is made up entirely of stars like the Sun, i.e. on average each star has the mass of 1 MSun. Under this assumption, approximately how many stars are there in our galaxy? Express this answer in billions of stars (1 billion = 109).

If we were to compare the ratio of the diameter galaxy and its thickness to the ratio of the diameter of a CD and its thickness (CD has a diameter of 12 cm and thickness of 0.6 mm), what would be the factor differentiating those ratios? Put differently, if the galaxy were scaled down to the diameter of a CD, how many times thicker or thinner would the galaxy be than the CD?
