Howling:Question about Gallifrey

Hey there. I recently got "Universe Sandbox" from Steam. As some may know, it allows you to simulate planets and the universe, with real physics. My question is, does anyone have the following info for Gallifrey?

Mass

Diameter

Density

Total Velocity

Rotation Period

SPOILERS FOR THE END OF TIME

What I want to do, is introduce Gallifrey into the orbit of Earth, so that I can see what would happen had Gallifrey not been returned
