Question
Visualize the model of the Sun as the beach ball [1,338,000 km = 40 cm), and the scale distance separating it and Alpha Centauri, the nearest star. Compare this to the scale size of the Milky Way (500 ly = 1 mm) and the scale distance between it and the Andromeda Galaxy, the nearest spiral galaxy. Which are closer relative to their sizes: stars or galaxies? To do this, calculate the number of stellar diameters between stars and the number of galactic diameters between galaxies on their respective scales, The smaller of these numbers will tell which objects are relatively closer. Be sure to state which are closer relative to their size. Use the scaled diameters of the Sun and the Milky Way to represent sizes of stars and galaxies in general. Use the scaled distances to Alpha Centauri and the Andromeda Galaxy to represent distances to stars and galaxies in general.Explanation / Answer
42.distance between sun and proxima centauri=4.22 light year
1 light year=9.461*10^12 km
4.22 light year=4.22*9.461*10^12 km
1338000 km=40 cm
4.22*9.461*10^12 km=1193585052 cm
43.distance between milky way and andromeda=2.5 million light year=2500000ly
500 ly=1mm
2,500,000 ly=5000 mm
44.Normally sun is closer to proxima centauri than milky way to andromeda but according to the scale we have chosed distance between milky way and andromeda(5000mm) is closer than distance between sun and proxima (1193585052 cm) centauri.
