Really none, there is no actual planet that has the exact same gravity, some can be close, like saying it Gforce was 2000, and another was 2000, but actually its like 2000.01010203053232 and 2000.21020103020310. Mars and Venus are roughly the same size as earth (and thus have about the same gravity), but I don't think any planet in our solar system is exactly the same as earth. Gravity is determined by mass; the planet in our solar system with a mass closest to earth is Venus. Venus' gravity is 8.87 ms-2 whereas the Earth's gravity is 9.86 ms-2. Mars's gravity is 3.71 ms-2.
Mars
Earth is the most massive terrestrial planet, so it has the highest surface gravity.
Among the known planets, Venus has the most similarities to Earth in terms of size and gravity. However, with its thick atmosphere of carbon dioxide, extreme temperatures, and lack of liquid water on its surface, Venus is not as Earth-like as Mars. Mars has a similar day length, reasonable temperatures at times, evidence of past water flow, and lower gravity compared to Earth.
The planet similar in size to Earth is Mars.

Earth & Venus.
Venus.
That is Saturn. For example, if you weigh 100 pounds on Earth, you would weigh 106.4 pounds on Saturn.

It compresses it. This is the reason why the Earth is the most dense planet in the Solar System.

That's Mars.
Venus is most similar in size and mass to Earth. Both planets are considered terrestrial planets and have similar compositions and densities, which is why they are often referred to as "sister planets."
