Hello, some more data about the situation: Planet 1 - fixed on the center of the referential Planet 2 - initial distance = 3 AU (start_x= 3 AU, start_y = 0) Planet 3 - initial distance = 6 AU (start_x= 6 AU, start_y=0) So Planet 2 is on the "middle" of the system. Planet 1 is about...

Hello, Let's consider a small 3 planet system. One of the planet's is fixed and is a lot heavier than the others. The acelleration is mP2 * aP2 = - FP3 - FP1 From with the velocity is derived with allows to calculate the positions of the planet's in a simulator program. After running the...

Hello, I have expression for the aceleration of a planet in the orbit of another planet and need to get the expression for it's velocity. The aceleration expression came from the Gravitacional Force within the gravitacional field of the planets. F=ma F=(-G.m1.m2/r^3) * position_vector Where r...

Oh... that's why couldn't get a Velocity experssion like that. The second is for velocity, taken from the mecanical energy expression and using e<0. So since velocity is a vector, v = vx + vy and we have an expression for the scalar value of v, how can we get each of the components? This is...

Hello, considering a Planet 1 and a Planet 2, where 1 is extremely heavier than 2 and 2 is going in Planet 1's orbit. Two questions 1) howto get the expression v = - G m2 m1 / r 2) if we consider the energy < 0, we can get to an expression as v < sqrt (2GM2 / r) howto get Vx and Vy...
