The planet which revolves round the sun in a clockwise direction is

Analyze the question: It asks which planet revolves round the Sun in a clockwise direction (as seen from above the Sun's north pole).

Concept: All eight planets orbit the Sun in the same direction, which is counterclockwise when viewed from above the Sun's north pole. This is called prograde motion and comes from the rotation of the original solar nebula. So strictly speaking, no planet revolves clockwise around the Sun.

The question is probably confusing revolution with rotation. Most planets rotate (spin on their axes) counterclockwise. Two are exceptions:

• Venus rotates clockwise (retrograde rotation).
• Uranus is tilted about 98°, so it rotates on its side, and its spin is also considered retrograde (clockwise).

Checking the options:

• A. Jupiter: orbits and spins counterclockwise.
• B. Mars: orbits and spins counterclockwise.
• C. Saturn: orbits and spins counterclockwise.
• D. Uranus: orbits counterclockwise, but its spin is retrograde (clockwise). It is the only option that is an exception to the general pattern.

Note that the wording is technically flawed. Uranus's orbit is still counterclockwise, and it is its rotation that is clockwise. Venus would be the usual example, but it isn't among the options.

Exam tip: Remember "Venus and Uranus spin backwards." If a question asks about a planet moving "clockwise" or "opposite to the others," pick one of these two.
