What single factor resulted in the moon today being so very much different than present-day earth?.

The single factor that resulted in the moon today being so very much different than present-day earth is the moon's small size.The sole natural satellite of Earth is the Moon. The Moon is the fifth biggest satellite in the Solar System, with a diameter that is around one-fourth that of the Earth (equivalent to Australia's width). The Moon is a planetary-mass object that developed as a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term. It lacks any significant atmosphere, hydrosphere, or magnetic field. It is larger than any of the known dwarf planets and is the largest (and most massive) satellite relative to its parent planet. About one-sixth of Earth's gravity is present on the surface (0.1654 g). The only satellite in the Solar System known to have a higher surface gravity and density is Jupiter's moon Io.To know more about moon click here:https://brainly.com/question/13538936#SPJ4
