General Information Edit

Ma'at and it's star are both named after Egyptian deities. Ra is the god of the Sun, while Ma'at is the goddess of justice and the regulation of the Earth. The reason for this planet's naming was due to the high ESI rating that it scored. It has no life, nor does it have any satellites. Large circular blotches, which are lighter than the rest of the ground, dot the planet's surface. These lighter blotches have also been shown to have a lower altitude than the rest of the surface, suggesting that these areas were once the location of lakes. The soil of the planet is generally a brownish or yellow hue.

Physical Information Edit

The planet has a diameter of about 7058.35 miles or 11359.31 kilometers. It has a density of 5.8993 g/cm 3. Its effective temperature is that of 4.6744 degrees Fahrenheit or -15.1808889 Centigrade. It has an extremely high ESI of 0.89. Its albedo is around 0.25. Its rotation period is 15 hours, 38 minutes, 23 seconds long. Its gravity on the equator is 0.94 g. Its gravity on the poles is about 0.96 g.

Orbital Information Edit

Ma'at has an elliptical orbit, its parent star is Ra (RS 0-6-201293-868-6-3-77-1417). Its orbital period (One Ma'atan year) is 139.942 Earth years. Its pericenter epoch is 2000.01.01, 12 hours. Its semi-major axis is 43.243 AU and the pericenter distance (Closest approach) is that of 42 AU. Its orbit eccentricity is 0.024. Its inclination is around 69 degrees. The Roche limit for any satellite is 5361.817 miles or 8629.008018 kilometers. If any satellite gets in orbit closer than that, it will break apart. Ma'at's influence sphere has a radii of 0.135 AU.
