Habitable alien planet,artwork. This Earth-like planet has two moons and is located near a nebula (background colours). A planet's orbit and its size have to fit within a narrow range for it to have a surface temperature suitable for liquid water,and for it to retain an atmosphere. The background colours are caused by hot young stars heating the dust and hydrogen gas in the nebula | |
