Our solar system is about 8,000 parsecs from the center of the Milky Way Galaxy. What is the distance from the center of the Milky Way Galaxy to the Sun in miles?

One parsec = 3.086 x 10^13 kilometers

Milky Way is 10^18 across

The answer is 1.53 x 1017 miles but I cannot figure out how they got that answer

The Milky Way is about 30,000 kiloparsecs across and is shaped like a disk, and is about 600 parsecs thick. The typical distance between stars in the galaxy is about a parsec. Assume that most stars are about the size of the Sun. How many stars would it take to completely fill up the entire volume of the Galaxy? Compare that to the actual number of stars in the Milky Way. Discuss whether or not stars will ever hit each...

Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0 ✕ 1011 solar masses. A star orbiting near the galaxy's periphery is 5.7 ✕ 104 light-years from its center. (a) What should the orbital period (in y) of that star be? (b) If its period is 5.7 ✕ 107 years instead, what is the mass (in solar masses) of the galaxy? Such calculations are used to imply the existence of other matter, such as...

Q: How far does the Sun falls towards the center of our Milky Way galaxy every year as it orbits the Galactic Center. Some details about the Sun’s orbit are:             radius = 8.0 kpc = 2.469 x 10^17 km             speed = 220 km/sec Thanks for the help! :)

The observable universe contains about 2 trillion galaxies. Our solar system belong to one of these galaxies and is called the Milky Way galaxy. Like the Earth revolves around the sun, the sun also revolves around the center of our galaxy, once every 2.5 × 108 years. Assume that each of the stars in our galaxy has the same mass as our sun and the stars are uniformly distributed in a sphere about the galactic center, find the number of...

Our solar system is roughly 2.28 x 1020 m away from the center of the Milky Way galaxy, and the system is moving at roughly 227.7 km/s around the galaxy's center. Since most of the galaxy's mass is near its center (and we are on an outer arm of this spiral galaxy), let's model the galaxy has a spherical mass distribution (like a single, giant star that our system is orbiting around). What is the mass of the galaxy (according...

At the center of our galaxy, the Milky Way, there is an object known as Sagittarius A*. Astronomers believe this is a black hole. Evidence for this is that, over several years, astronomers have observed other stars in orbit around Sagittarius A*. One such star has a period of its orbit around Sagittarius A* of 15.2 years and the radius of its orbit has been measured to be 1.42  1014 m. (a) Assuming this orbit is circular, and ignoring...
