Asteroids are safer in a circular orbit than an elliptical orbit because being in an elliptical orbit causes them to tumble in an erratic manner. Larger asteroids are sometimes referred to as planetoids.
The reed is safe because it bends to the wind and lets the wind blow it all around. The reed is tough and flexible so it does not break when the wind blows.
Yes, because the asteroid would crash into Earth and killed people .

Both N.A.S.a and the astronauts , worked very closely as well as tirelessly to get the Apollo 13 astronauts home and safe.
