8.5 Orbits of comets, moons and planets question 1
This question is about astrophysics.
Diagrams A , B , C and D show different orbital paths for object Y orbiting object X .
Table 1 gives some possible names for object X and object Y .Complete the table by placing one tick ( ✓ ) in each row to show which orbital path is correct for each combination of object X and object Y .Each orbital path may be used once, more than once, or not at all.
