Statistical inversion method for binary asteroids orbit determination I.Kovalenko, D. Hestroffer, A. Doressoundiram, N. Emelyanov, R. Stoica ikovalenko@imcce.fr (IMCCE - LESIA, Paris Observatory) Introduction We focus on the study of binary asteroids, which are common in the Solar system from its inner to its outer regions. ... Particularly, we use the Metropolis-Hasting algorithm with Thiele-Innes equation for sampling the orbital elements and system mass through the sampling of observations. ...

... Rocket History . Most people have at least an intuitive notion of the center of gravity (CG) of an object: it is the point on which the object can be perfectly balanced. Grab a broom at one end and the other end tries to drop down; grab it at its center of gravity, and it stays balanced, neither end tipping over. ... Suppose we have a rocket of total mass 2M , of which M is payload and M is fuel. ... Total mass . ... Each time the velocity increases by one notch, the mass doubles . ...
