How does the mass of the Earth compare to the mass of moon?
The mass of the Earth is significantly greater than the mass of the moon. The Earth has a mass of approximately 5.972 × 10^24 kilograms (5.972 sextillion kilograms), while the moon has a mass of approximately 7.348 × 10^22 kilograms (73.48 billion kilograms).
In other words, the mass of the Earth is about 81.3 times greater than the mass of the moon. This significant difference in mass is one of the reasons why the moon orbits around the Earth and not the other way around.
To compare the mass of the Earth to the mass of the Moon, follow these steps:
Step 1: Find the mass of the Earth.
The mass of the Earth is approximately 5.97 x 10^24 kilograms.
Step 2: Find the mass of the Moon.
The mass of the Moon is approximately 7.35 x 10^22 kilograms.
Step 3: Compare the masses.
Divide the mass of the Moon by the mass of the Earth.
(7.35 x 10^22 kg) / (5.97 x 10^24 kg) ≈ 0.0123
Step 4: Interpret the comparison.
The mass of the Moon is approximately 1.23% of the mass of the Earth.
Therefore, the mass of the Earth is approximately 81.3 times greater than the mass of the Moon.
