A new study has examined the moon formations and concluded that only certain types of planets can form moons that are large in respect to their host planets.
The moon controls the length of the day and ocean tides, which affect the biological cycles of life forms on our planet.
The moon also contributes to Earth's climate by stabilizing Earth's spin axis, offering an ideal environment for life to develop and evolve.
Because the moon is so important to live on Earth, scientists conjecture that a moon may be a potentially beneficial feature in harboring life on other planets.
