Natural abundances vary based on the planet and its formation history. For example, Mars and Earth have different oxygen isotope ratios. It has been suggested that the moon was formed when a planet-sized object struck a glancing blow on Earth. Although the cores remained largely intact, the remnants of these two bodies eventually reformed into Earth and moon. Explain how you could use isotopic analysis to support this theory.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
