The table shows the closest and farthest distances of the eight planets from the Sun, in millions of kilometers. | Planet | Closest | Farthest | |---|---|---| | Mercury | 46 | 70 | | Venus | 107 | 109 | | Earth | 147 | 152 | | Mars | 205 | 249 | | Jupiter | 741 | 817 | | Saturn | 1{,}350 | 1{,}510 | | Uranus | 2{,}750 | 3{,}000 | | Neptune | 4{,}450 | 4{,}550 | Which planet has the **greatest difference** between its closest and farthest distances from the Sun?

Compute farthest $-$ closest for each candidate (skip Mercury–Venus–Earth, all small): - Mars: $249 - 205 = 44$ - Jupiter: $817 - 741 = 76$ - Saturn: $1{,}510 - 1{,}350 = 160$ - **Uranus: $3{,}000 - 2{,}750 = 250$** ← largest - Neptune: $4{,}550 - 4{,}450 = 100$ Neptune is *farthest* from the Sun overall but has a comparatively narrow orbit-distance range. The trap is to read "greatest" as "largest absolute distance" (Neptune) when the question asks about the *spread*.
