If an object at the center of the Milky Way Galaxy has a linear diameter of 1.0 AU, what is its angular diameter as seen from Earth? Assume the distance to the center of the galaxy is 8.3 kpc. (Hint: Use the small-angle formula, Chapter 3.)
Added by Alba C.
Step 1
The distance to the center of the galaxy is given in kiloparsecs (kpc), and 1 parsec (pc) is approximately equal to 206,265 Astronomical Units (AU). So, 8.3 kpc is equal to 8.3 * 206,265 = 1,711,999.5 AU. Show more…

The diameter of our disk-shaped galaxy, the Milky Way, is about 1.0Ă—10^5 light-years (ly). The distance to the Andromeda galaxy, which is the spiral galaxy nearest to the Milky Way, is about 2.0 million ly. If a scale model represents the Milky Way and Andromeda galaxies as dinner plates 25 cm in diameter, determine the distance between the centers of the two plates.

The diameter of our disk-shaped galaxy, the Milky Way, is about $1.0 \times 10^{5}$ light-years (ly). The distance to the Andromeda galaxy (Fig. Pl. 51$)$ , which is the spiral galaxy nearest to the Milky Way, is about 2.0 million ly. If a scale model represents the Milky Way and Andromeda galaxies as dinner plates 25 $\mathrm{cm}$ in diameter, determine the distance between the centers of the two plates.
Jupiter has a diameter of 140,000 km and is 4.2 AU from the Earth. What is the approximate angular diameter of Jupiter in the sky in units of arc sec? (1 AU = 1.5E8 km)
