At first glance, since this planet is more massive (3 to 4 times) than the earth, I thought I wouldn’t want to go there because I would weigh too much. However, it is larger than the earth (between 1.3 and 2 times) so:
The force of gravity depends on a few things. First, it depends on your mass and the mass of the planet you are standing on. If you double your mass, gravity pulls on you twice as hard. If the planet you are standing on is twice as massive, gravity also pulls on you twice as hard. On the other hand, the farther you are from the center of the planet, the weaker the pull between the planet and your body. The force gets weaker quite rapidly. If you double your distance from the planet, the force is one-fourth. If you triple your separation, the force drops to one-ninth. Depending on the actual diameter, it might not be so bad.
Particle physics = oxymoron.
