Chapter 1, Problem 81AP
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.

The nearest neutron star (a collapsed 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
~ 10²' m and thickness ~ 1019 m, estimate the number of neu-
tron stars in the Milky Way to the nearest order of magnitude.
Figure P1.81
The nearest neutron star (a collapsed star made primarily of neutrons) is about 3.00 × 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.63) 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.
A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 km. 1 year = 3.156 ×× 107 s.
How many meters are there in 1.70 ly?
Express your answer using three significant figures. Express in scientific notation!
1.70 ly = _________________m
