Phantos
and
Elmora
Alpha Mensae II & III
   Double Planet
   Phantos: Temperate Terrestrial World
   Elmora: Dead Lunar World

Distance from sun: 85 million miles
Distance between Phantos and Elmora: 14,150 miles
Orbital Period: 342.67 earth days
Solar Day*: 16:15 earth hours

Diameter of Phantos: 5,818 miles
Gravity of Phantos: 0.6 g

Diameter of Elmora: 2,477 miles
Gravity of Elmora: 0.2 g

Axil Tilt of Both Planets: 19°
Moons: none
Notes: Phantos colonised in 5509 A.D.
.......Phantos terraformed in the 56th to 58th Centuries.


*Because the same sides of both planets always face eachother
the length of day on Phantos is equal to both the day length on Elmora
and orbital period of the two planets about eachother.
