Construct Your Own Problem Consider a star moving in a circular orbit at the edge at a galaxy. Construct a problem in which you calculate the mass of that galaxy in kg and in multiples of the solar mass based on the velocity of the star and its distance from the center of the galaxy. Figure 34.26 Distances to nearby stars are measured using triangulation, also called the parallax method. The angle of line of sight to the star is measured at intervals six momma apart, and the distance is calculated by using the known diameter of the Earth's orbit. This can be done for stars up to about 500 ly away.
If the universe is infinite, does it have a center? Discuss.
Parallaxes of stars are sometimes measured relative to the positions of galaxies or distant objects called quasars. Why is this a good technique?
The nearest neutron star (a collated star made primarily of neutrons) is about 3.00 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.81) is roughly a disk of diameter 1021 m and thickness 1019 m, estimate the number of neutron stars in the Milky Way to the nearest order of magnitude. Figure P1.81
A light year is the distance traveled by light in one year. Identify the distance to a nearby galaxy that is 2X106 light years away. (The speed of light is 3X108m/s) A. 10´1015m B. 6´1012m C. 2´1022m D. 1´1018m
Hubble law describes how the speed of recession of distant galaxies varies with the distance from Earth v = Hod, Ho = 2.3 × 10-18 [s-1] Estimate the distance of an object when it moves very close to the speed of light c = 3.00 x 108 [m/s] relative to Earth.
Why is it difficult to study our own galaxy? O The sun obscures the view O We are within it and thus cannot see it from the outside O Earth's position is not ideal compared to other planets (within the galaxy) for viewing our galaxy O Parts of it are too far away to see
