What are Properties? Properties
The composition of this object. (or not) Most likely not.
The gravitational pull on the surface of this object (for those objects that have surfaces).
|Mean density||/base/schemastaging/celestial_object_extra/mean_density||/type/float g/cm³||
The mean density of this object, if applicable.
|Mean radius||/base/schemastaging/celestial_object_extra/mean_radius||/type/float km||
The mean radius of this object (for those objects can reasonably be said to have a radius)
|Surface area||/base/schemastaging/celestial_object_extra/surface_area||/type/float km²||
The approximate surface area of this object (for those objects which can reasonably be said to have surfaces).
|Escape velocity||/base/schemastaging/celestial_object_extra/escape_velocity||/type/float m/s||
The speed required for an object (such as a spacecraft) to break free from the celestial object's gravity.
|Equatorial circumference||/base/schemastaging/celestial_object_extra/equatorial_circumference||/type/float km||
The circumference of this object at its equator.
