Question : 50 [SSC SO 2008]

Which is the coldest among the following?

a) Pluto

b) Mercury

c) Earth

d) Mars

Answer: (a)

Until it lost its planetary status in 2006, Pluto was the coldest with an estimated surface temperature between -235 and -210 degrees Celsius.

But Pluto has now been relegated to the status of a Dwarf Planet. Pluto has always had the ‘honor’ of being the coldest planet with an average temperature between -360 to - 400 degrees Fahrenheit.

This is because it is so far away from the sun: it is over 40 times further from the sun than planet Earth. Pluto also has no internal heat source and it even orbits in a ring of ice debris.
