Question

Planet A is at a distance of 9.35 × 10⁶ km from Earth and planet B is 6.27 × 10⁷ km from Earth. Which planet is nearer to Earth?

Answer 1

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.
