this fcc formula to get the orbital period //T = (2 * PI * SQRT[earthRadius + avgAlt] / GM);
this on google. link :http://www.physicsclassroom.com/class/circles/Lesson-4/Mathematics-of-Satellite-Motion //T = SQRT [(4 • pi2 • R3) / (G*Mcentral)]
col-lg-6will use 6 columns on a large screen, and the full width of anything that is smaller than the bootstrap breakpoint for
