How many Gemini missions were there in a two year period?

Answer 1

In the two year period 1784 to 1786 there were none.

In any arbitrarily chosen two year period since the brginning of the universe, the chance

of Gemini missions on Earth is vanishingly small. For all practical purposes it is zero. However,

it is possible that there were Gemini missions on other inhabited planets. If the universe is

infinite, it is a mathematical certainty that there are always Gemini missions occurring somewhere,

and always people asking how many of them there were, and an infinity of people providing

facetious answers.
