Planets are massive celestial bodies that orbit a star or stellar remnant. They are of many different sizes and compositions. Planets may have natural satellites (moons ) and may or may not be inhabited. Every planet has a unique infographic, but most of them cannot be interacted with. Travel from planet to planet requires use of the Galaxy Map .
Within each planetary system, there will usually only be one location to land / dock. Most often this will be a planet, but it may be a moon or starship instead. Many planets can be scanned from space for minerals or other collectibles, but not landed upon. There are even asteroids containing valuable metals or other objects hidden in the belts.

Other Worlds [ ] These worlds are known to exist in the Milky Way galaxy, but their locations are not specified via the Galaxy Map .
Properties [ ] Mass Effect provides the radius of planets (in kilometers), and for planets with a solid surface it further provides the surface gravity (as a proportion of Earth 's surface gravity). From these, it is possible to derive the mass (and density) for any planet with a surface gravity.
Isaac Newton's gravitational constant is 6.67×10-11 m3 kg-1 s-2 which would be 6.67×10-20 km3 kg-1 s-2 when dimensioned for kilometers. Earth's surface gravity, g -2 , which is 9.81×10-3 kms-2 . According to Newton's Law of Universal Gravitation , the mass of any body, M ar2 G-1 a r G Mass Effect , s a = sg s r 24 kg, the mass of a planet will be:

Trivia [ ] Casey Hudson created a random planet generator in Microsoft Excel (labeled PLANET-GEN) which would also give out accurate statistical details. The rest of the development team used it to create a list of hundreds of viable planets, combined with an in-house tool in Unreal Engine 3 , to map one solar system at a time and add those planets in.[1] References [ ]
