Which planet is closest to size of Earth?
It is a little more complicated than that, but that will get you close.

To determine which planet has the gravitational force that is closest to Earth's, we need to compare the gravitational accelerations of different planets to that of Earth. The gravitational acceleration can be calculated using Newton's law of universal gravitation:
Acceleration due to gravity (g) = (G * M) / (R^2)
where:
- G is the gravitational constant (approximately 6.67430 × 10^-11 m^3 kg^-1 s^-2),
- M is the mass of the planet,
- R is the distance between the center of the planet and the object.
Using this equation, we can calculate the gravitational accelerations for each planet and compare them to Earth's acceleration (approximately 9.8 m/s^2).
Here are the approximate values of the gravitational accelerations on different planets compared to Earth:
- Mercury: 3.7 m/s^2
- Venus: 8.87 m/s^2
- Mars: 3.71 m/s^2
- Jupiter: 24.79 m/s^2
- Saturn: 10.44 m/s^2
- Uranus: 8.69 m/s^2
- Neptune: 11.15 m/s^2
From this comparison, we can conclude that Venus has the gravitational force that is closest to Earth's gravitational force. Venus has a gravitational acceleration of approximately 8.87 m/s^2, which is relatively close to Earth's 9.8 m/s^2.
Remember, these values are approximations and can vary depending on factors like the planet's mass and radius.
