AG1-43 is an imaginary world described in the History Channel exobiology documentary "Alien Faces". AG1-43 is a huge terrestrial planet with a beautiful ring system and some small moons orbiting around it. The planet orbits a bright F-class star.
It is a large desert world, where the climate is arid and liquid water is scarce, covering only 10% of the world's surface. Its gravity is three times stronger than Earth's, meaning that the atmosphere is much thicker, and holds a higher concentration of oxygen. Because of this, giant flying organisms, that can stay airborne for as long as they need, can be found soaring in the planet's skies.
