The gravity tractor, is a proposed spacecraft that will fly close to an asteroid whose trajectory threatens to impact the Earth.

Answer:

$F_g=461lb_f$

Explanation:

First calculate the mass of the asteroid. To do so, you need to find the volume and know the density of iron.

If r = d/2 = 645ft, then:

$V = \frac{4}{3} \pi r^3$

$V = \frac{4}{3} \pi r^3\\V = 1.124\times10^{9}ft^3\delta_{iron}=m/V=491lb/ft^3m=V\times\delta=5.519\times10^{11}lb$

In order to find force, use Newton's universal law of gravitation:

$F_g=G\frac{m_1m_2}{d^2}$

Where,

G= the gravitational constant:

$G= 1.068846 \times10^{-9} ft^3 lb^{-1} s^{-2}$

$F_g=461lb_f$
