Does any planet have the same gravity as the earth,?

In order to have the same surface gravity as the earthy another planet would have to be exactly the same weight and size as the earth. The gravitation of any heavenly body depends upon weighty or mass. The surface gravity depends upon mass and size, or distance from the center of gravity.

Since no two planets are exactly alike in these respects the surface gravity of each is different.

Gravity gives weight to the objects on a planet. Your weight on earth would be different on each of the other planets, Mars is both lighter and smaller than the earth. If your weight is 100 pounds on earth it would be only 36 pounds on Mars. On Venus you would weight 85 pounds and on little Mercury only 25 pounds. But your muscles are trained to cope with earth's heavier gravity. Imagine the giant sized steps and aerial leaps you could take on these planets.

Imagine the wearisome time you would have on the heavier planets. On Neptune your 100 pound body would weigh. 112 pounds, On Saturn you would weigh 117 pounds, On giant Jupiter you would have to drag around a body weighing 264 pounds,
