- The center of our Galaxy is about 7500 parsecs from Earth. What would be the parallax angle of a star near the center of the Galaxy? Could this angle be measured with current technology?using the center-of-mass equations or the Carter of Mass Calculator (under Binary-Star Basics, abova), you will investigate a specific binary star system. Assume that Star 1 has m, 3.2 solar masses, Star 2 has m,-0.9 solar masses, and the total separation of the two (R) is 34 All (One AU is Earth's average distance from the Sun) (2) What is the distance, d. (In Au) from Star 1 to the center of mass? AU (b) What is the distance, dy On Au) from Star 2 to the center of mass AU ( what is the ratio of d, tod?A supernova in a distant galaxy is observed to be having an absolute magnitude of -19 and an apparent magnitude of 17. Estimate the distance to the galaxy.
