Well yeah, I have been trying to perfect a Hohmann transfer in KSP (which is how to find velocity at a certain point in a orbit. To find V (Velocity) You need to do GM(2/r-2/a) which would be 1.766E+9(2/300,000- 2/300,000) For a minimus orbit that has a perigee of 300,000 meters and you want to know exactly how fast you are going at your perigee of 300,000 meters. Does anyone know how to decipher 1.766E+9 ??? I don't know how to convert it to scientific notation. And that means I cant make the calculation!!! Any help appreciated!
