    It’s hard to compare to exoplanets as we barely even know their sizes let alone densities. But in our solar system earth is the densest of 5.5g/cm3. Close are only Mercury 5.4 and Venus 5.2. Then you have Mars 3.9, Io 3.5, Moon 3.3, Europa 3.0, Triton 2.0, Ganymede 1.9, Pluto 1.9, Callysto 1.8…

    Is not a big sample size, but I’d still assume that such dense planets (high gravity for their size) as Earth are not very common.

    Human planet also has an unusual core made of iron which creates a crushing gravity. Gravity is actually so strong that even the gas that sorrounds the planet pushes on everything with a pressure of over 10 tons / m2. And when weather makes the pressure slightly less severe humans are like “I don’t feel so good, the atmosphere is not crushing me nearly enough”.
