The best radioisotope to use in powering planet and space exploration is plutonium-239 since it has the longest half-life of 21400 years.

What is Half-Life of radioactive element?

The half-life ofa radioactive element is the time it takes for half the amount of atoms in the element to spontaneously decay.

The half-life of radioactive elements vary.

The half life of the given radioactive elements are as follows:

lithium-5 is 3.038×10^-22 seconds
uranium-240 is 14.1 hours
carbon-14 is 5700 years
plutonium-239 is 21400 years

Therefore, the best radioisotope to use in powering planet and space exploration is plutonium-239 since it has the longest half-life of 21400 years.
