Debris Disk. By NASA/JPL-Caltech

Debris disk

A debris disk is a circumstellar disk of dust and debris in orbit around a star. Debris disks have been found around both mature and young stars, as well as at least one debris disk in orbit around an evolved neutron star. Younger debris disks can constitute a phase in the formation of a planetary system following the protoplanetary disk phase, when terrestrial planets may finish growing.Read More

Iron Planet

An iron planet is a type of planet that consists primarily of an iron-rich core with little or no mantle. Mercury is the largest celestial body of this type in the Solar System (as the other terrestrial planets are silicate planets), but larger iron-rich exoplanets may exist. Iron-rich planets may be the remnants of normal metal/silicate rocky planets whose rocky mantles were stripped away by giant impacts.Read More

Mini Neptune. By Krischan


A Mini-Neptune is a planet of up to 10 Earth masses, less massive than Uranus and Neptune, which have about 14.5 and 17, respectively. Mini-Neptunes have thick hydrogen-helium atmospheres, probably with deep layers of ice, rock or liquid oceans made of water, ammonia, a mixture of both, or heavier volatiles. These planets have small cores made of low-density volatiles.Read More

Planet Atmosphere Demo. By Krischan

Planet Atmosphere Demo

These older planet experiments are the ancestor of the Brush Planet algorithm based on my Planet Creator code. They have a cool space to surface transition effect with their atmospheres (if available) so don’t miss the demo and the four videos below. I don’t know which planet template is the best but my favourite is the Jupiter with its rotating clouds. Read More
