Question
Pergunta 5 2 pts If 20% of Sun-like and lower-mass (dwarf) stars have terrestrial-like planets orbiting in their habitable zones, as astronomers currently estimate, then what does this mean for the population of habitable planets (terrestrial planets with an atmosphere and surface conditions allowing for liquid water) in the Milky Way galaxy? There are likely to be hundreds of habitable planets in the Milky Way (but not a million or more). O There are likely to be more than a billion habitable planets in the Milky Way. O There are likely to be only a few habitable planets in the Milky Way (not more than one hundred). O Earth is likely the only habitable planet in the Milky Way. There are likely to be millions of habitable planets in the Milky Way (but not a billion or more).Explanation / Answer
The answer is - There are likely to be millions of habitable planets in the Milky Way (but not a billion or more).
