The size of Earth can be accurately estimated by satellite measuring devices and simple geometry. The density of Earth can be derived by the effect of its gravitation on other nearby planetary bodies.
Size: The Moon has about 1/4 of the diameter of Earth. Mass: The Moon has about 1/81 of the mass of Earth.
Venus is closest to the Earth in size and mass. Its diameter is around 95% of Earths, while its mass is around 81.5% of Earths.
The mass of an exoplanet is typically determined using methods such as the radial velocity technique, where the gravitational pull of the planet causes measurable wobbles in its host star's motion. Another method is the transit method, which measures the amount of starlight blocked when a planet passes in front of its star, allowing calculations of the planet's size and density. By combining these data, scientists can estimate the mass of the exoplanet. The mass is often expressed in relation to Earth's mass (e.g., in Earth masses or Jupiter masses).
Venus is the planet closest in mass to Earth, with a mass about 81% that of Earth.
It is near Earth in size. About 81.5% of Earth's mass.

The moon is smaller than the Earth so that would mean the size is smaller and the mass is also smaller because the mass depends on the size of the object so the moon would have less mass than Earth.
Venus is the planet closest in mass to Earth, with a mass about 81% that of Earth.
If Earth shrank in size but not mass, the compression would greatly heat Earth's interior. Surface gravity would increase.
The mass on the moon and the earth is the same but the weight changes.
It is near Earth in size. About 81.5% of Earth's mass.
Earth's diameter about 7925 miles. Moon's diameter about 2160 miles. The diameter of the Moon is 3,474 km and the diameter of the Earth is 12,742 km. This makes the Moon approximately 27% the size of the Earth. The mass of the Moon is 7.347 x 1022 kg and the mass of the Earth is 5.97x 1024 kg. The mass of the Moon is only 1.2% of the mass of the Earth.

Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.
Venus is most similar to Earth in terms of mass and diameter. Venus is almost the same size as Earth, with a diameter about 95% that of Earth, and its mass is about 81.5% of Earth's mass.
