This model of a realistic exoplanet is one of those moons/exoplanets one might expect to find in orbits of far away stars. This planet has an appearance of a black rocky planet covered with a pinkisch colored ice. Its size like Pluto or the moons of Jupiter. Its ice comes from its former atmosphere. This atmosphere however is long gone due to its small size and low gravity.
Technical information
In real life, this planet would have a diameter of around 2.000 km in diameter. Some 3d programs do not display objects of this size very well. In order to avoid complications, and because most users want to decide the exact diameter themselves, the model itself is not scaled to the real life size.
