Below i will give you a description of my exoplanet

 

Mass .226 earths, density 5.72 g/cm3, radius .60 earths, surface gravity is .63 earths

It has 1 moon that has 5% the mass of the main world orbiting 250,000 miles above the surface.

It orbits a sun like star, same luminosity and mass every 385 days at 1.05 au, eccentricity is .02

The average surface temperaturer is 300 Kelvin

It has 75% water and 25% land, the crust ranges from 5-30 miles thick

The salinity of the oceans are 5-7% with a mean depth of 18,000 feet

The atmospheric composition is 70% nitrogen, 20% oxygen, 5% xenon, 3% carbon dioxide, 1% water vapor and the rest methane, argon, carbon monoxide, neon and trace amounts of ozone and hydrogen at an atmospheric pressure of 1.8 bar

The planet has a molten core and is surrounded by a magnetic field 60% as strong as Earths

The planet spins on its axis every 18 hours and has a tlt of 25 degrees

The planet is currently 4.2 billion years old

 

How long can a planet like this retain its atmospheric gases?

Would this planet support humans if they decided to settle here?
