Q. No.Both the earth and the moon are subject to gravitational force of the sun. As observed from the sun, the orbit of the moon:
| 1. | will be elliptical |
| 2. | will not be strictly elliptical because the total gravitational force on it is not central |
| 3. | is not elliptical but will necessarily be a closed curve |
| 4. | deviates considerably from being elliptical due to the influence of planets other than the earth |
Subtopic: Kepler's Laws |

In our solar system, the interplanetary region has chunks of matter (much smaller in size compared to planets) called asteroids. They:
| 1. | will not move around the sun, since they have very small masses compared to the sun. |
| 2. | will move in an irregular way because of their small masses and will drift away into outer space. |
| 3. | will move around the sun in closed orbits but not obey Kepler’s laws. |
| 4. | will move in orbits like planets and obey Kepler’s laws. |
