Pluto Identified as the Odd One Out
The question asks us to identify the celestial body that is different from the others listed: Mercury, Venus, Earth, and Pluto.
Understanding Solar System Classifications
Our solar system has various types of celestial bodies, including planets, dwarf planets, asteroids, and comets. The International Astronomical Union (IAU) defines a planet based on three criteria:
- It must orbit the Sun.
- It must have sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape.
- It must have cleared the neighbourhood around its orbit.
Analyzing the Options
Let's look at each option:
Mercury, Venus, and Earth are all classified as planets. They are inner, rocky planets (terrestrial planets) located closer to the Sun. They meet all three IAU criteria for being planets.
Pluto, on the other hand, was considered the ninth planet for many years. However, in 2006, the IAU reclassified Pluto as a dwarf planet. This is primarily because Pluto has not cleared the neighbourhood around its orbit; it shares its orbital region with other objects in the Kuiper Belt.
Conclusion
Mercury, Venus, and Earth are recognized planets, while Pluto is classified as a dwarf planet. Therefore, Pluto is the odd one out based on its current astronomical classification.

Important Questions from Odd Man Out
Three of the following numbers are alike in a certain way and one is different. Pick the odd one out. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
