How to calculate linar velocity of planet orbit? This is perfect ! thanks a lot. Just to be sure , the α is always PI/2 or -PI/2 , no ? |

How to calculate linar velocity of planet orbit? @Joe ,It's determined because I choose to make all the planet rotate the same way. By the way when you talk about eccentricity , if you know a formula, it interest me a lot. |

How to calculate linar velocity of planet orbit? @JohnRennie I just notice why my result was wrong. I was using 1.49e8 instead of 1.49e11 because I use all value in km but didn't change my G constant. |

How to calculate linar velocity of planet orbit? @Joe , I know , but since I didn't found anything , I was testing this one |

How to calculate linar velocity of planet orbit? @Kyle I need the "initial" velocity , I already can update the velocity using nbody. If i should add a parameter I think that should be the eccentricity since it's surely something I'll be playing with too. By the way sorry for the confusion in my question , I have some difficulties to ask technical questions in english :/. Don't hesitate to suggest edition |

How to calculate linar velocity of planet orbit? that's one of the formulas I found but when i apply it , I got extremly high result (eg: for earth fixed vector is 29.783 and generated with your formula : 941690.7474866967) |

Planet's Moon attrated by sun i just tested that and the same happen , the moon orbit around the sun without noticing the earth , it's orbit speed is faster (because of the mass I guess). For the moon to remain in the same distance from earth , i need the force to be almost null , no? |

Planet's Moon attrated by sun the problem is that with the velocity of moon+earth , the moon do not stick around earth, it doesn't behave like a satelite of earth. (i mean by that , that the path between the two is not the same and it's visible after a little time , i can post video to see if you like |
