How many apples could fit in the volume of the earth?

If the Earth's radius is approximately 6780km.

Volume of sphere is V=4/3*π*r^3

Therefore,

V(earth)=4/3*π*(6780000)^3

V(earth)=1.31*10^21 cubic metres

Assuming the average radius of an apple is 5cm

Therefore,

V(apple)=4/3*π*(0.05)^3

V(apple)=5.24*10^-4 cubic metres

Hence, the amount of apple that could fit in the volume of Earth is

=V(earth)/V(apple)

=(1.31*10^21)/(5.24*10^-4)

=2.5*10^24

=2.5 Septillion apples

=2,500,000,000,000,000,000,000,000 apples :)

Why does Dr. Tyson believe that Pluto is America's favorite planet in Astrophysicist Chronicles Battle over Pluto?

Dr. Neil deGrasse Tyson does not consider Pluto a planet due to its size, orbit, and failure to clear its orbital path of debris, as defined by the International Astronomical Union (IAU) in 2006. He believes that the classification of Pluto as a planet was more of a sentimental attachment rather than a scientific one. Tyson argues that the reclassification of Pluto as a dwarf planet was a necessary adjustment based on our evolving understanding of our solar system.
