# What if Earth were the size of Jupiter? What would be different about life as we know it?

Jupiter is roughly $11$ times the diameter of the Earth, so has volume about $1300$ times the volume of the Earth.
If the Earth were the size of Jupiter but still the same density as it is now, then gravity would be $11$ times stronger at the surface (being proportional to the mass divided by the square of the radius), which would make it a little difficult for vertebrates similar to us to function - Imagine trying to carry your own weight plus $10$ times that.
