The correct comparison is:
Both are rocky planets, but only Venus spins in the same direction that Earth does.
To elaborate:
- Venus and Mercury are both rocky (terrestrial) planets.
- Venus spins on its axis in a retrograde rotation (opposite to most planets, including Earth), while Mercury rotates in the same direction as Earth but has a very slow rotation period.
- Venus is indeed hotter than Mercury despite being farther from the Sun due to its thick atmosphere and greenhouse gases. However, the particular statement regarding the direction does not compare size or atmospheric presence, which makes it the most accurate option offered.
