The non-procedural planet, Kepler-10c is portrayed with slightly more than a feasible amount of mass and an accurate radius, and is also shown as an ice giant when in reality, it is almost certainly a very large rocky planet much some of the large procedural ones.
Obviously, SpaceEngine have the data in its catalogs what was actual on the date of release (December 2013). It is not updated automatically.
Also, I'm HIGHLY skeptical that Kepler-10b, the scorched desert that orbits closer in, would have such a thick atmosphere. I would guess that even with 2.2 G of gravity, the atmosphere would be evaporating into space too fast to be retained solely due to the fact that it is hot enough to melt tungsten in some areas of the planet.
No, calculations shows that this planet can hold massive atmosphere. SpaceEngine uses the model of thermal dissipation of the atmosphere, and it calculated what atmosphere is still there.
