उत्तर
Distance between planet A and Earth = 9.35 × 106 km
Distance between planet B and Earth = 6.27 × 107 km
For finding difference between above two distances, we have to change both in same exponent of 10, i.e. 9.35 × 106 = 0.935 × 107, clearly 6.27 × 107 is greater.
So, planet A is nearer to Earth.
