re: Smallest exoplanet!

I assuming they mean 14x’s the mass? Uranus’s mass is 14 times of the Earth’s and Neptune’s Mass is just over 17 times that of the Earth

I wonder what the surface gravity is on that planet. Remember that gravitational force a planet exerts upon an object at the planet's surface is proportional to its mass and to the inverse of its radius squared. So Uranus is 0.91 G’s and Neptune is 1.19.

Being closer to its star, this planet is probably more dense then Uranus or Neptune. Its gravity could be in the 1.3+ range and it could have a lot of surface area.
