- Venus is the second brightest natural object in the night sky after the Moon, probably that is the reason why it was the first planet to have its motions plotted across the sky, as early as the second millennium BC.
- Unlike the other planets in our solar system, Venus and Uranus spin clockwise on their axis. Hence, statement 1 is not correct.
- A day on Venus is longer than a year. It takes Venus longer to rotate once on its axis than to complete one orbit of the Sun.
- That’s 243 Earth days to rotate once - the longest rotation of any planet in the Solar System - and only 224.7 Earth days to complete one orbit of the Sun. Hence, statement 2 is correct.
- Recently, the National Aeronautics and Space Administration (NASA) announced two new robotic missions to Venus.
- The two sister missions named DaVinci Plus and Veritas are aimed at understanding how Venus became an inferno-like world capable of melting lead at the surface.
- DaVinci Plus:
- It will be the first of the two, it will analyze the thick, cloudy Venusian atmosphere in an attempt to determine whether the inferno planet ever had an ocean and was possibly habitable. A small craft will plunge through the atmosphere to measure the gases.
- Veritas:
- It will be the second one seeking a geologic history by mapping the rocky planet’s surface.
- Venera and Vegas were the previous Venusian missions of Russia. Hence, statement 3 is not correct.

Analysis of Statements
To evaluate the correctness of the statements regarding Venus and Uranus, let’s break down each statement:
Statement 1: Venus and Uranus are the only planets of the solar system that spin anticlockwise about their own axis.
- This statement is partially true. While Venus and Uranus do have unique rotational characteristics, it is worth noting that Venus rotates retrograde (anticlockwise) while Uranus rotates on its side. However, it’s important to highlight that all planets generally rotate anticlockwise when viewed from above the North Pole, except for Venus and Uranus. Thus, this statement is misleading.
Statement 2: The rotation period of Venus is the longest for any planet of the solar system.
- This statement is correct. Venus has a rotation period of about 243 Earth days, making it the longest rotation period of any planet in the solar system. Additionally, its day is longer than its year, as it takes about 225 Earth days to orbit the Sun.
Statement 3: Venera and Vegas are the robotic missions of NASA to Venus.
- This statement is incorrect. The Venera missions were conducted by the Soviet Union, not NASA. The Venera program was notable for its successful landers that transmitted data from the surface of Venus. There is no well-known mission called "Vegas" related to Venus by NASA.
Conclusion
Based on the analysis:
- Correct Statement: 2
- Incorrect Statements: 1 and 3
Thus, the correct answer is option 'B' (2 only).
