    Stefan Go to setup under the edit menu and change your model units such that you get the right units for your mass. Your density is such that this model is getting close to the weight of the earth (E8). Eric

    OK. I change that now and get this. MASS = 2.8945595e+08 KILOGRAM. Is this 2.89 KG or is it 289 KG? Shall the decimal sign move to get the right value for me?

    2.8945e+8 is 289450000 KG E notation is move decimal to right # places for positive numbers and move left for negative. E-8 would be .000000028945... KG
