#### The **conservation** **laws** in the Euler problem about two attractive centers and the integration of the dynamic equations

The article establishes that Euler’s problem of two attractive centres contains another **conservation** **law** alongside with the energy **conservation**
one, which is also quadratic in velocities. These **conservation** **laws** and elliptic coordinates considerably simplify the procedure of trajectory equations generation.
