Two stars interact with each other. Star 1 has a mass 2×10^30⁢⁢  kg, and Star 2 has a mass 1×10^30⁢⁢kg. At a certain instant ( t=0), Star 1 is at the origin with zero velocity, and Star 2 is at ⟨-1.50×10^11,0,0⟩ m with a velocity ⟨0,-3.50×10^4,0⟩ m/s. Later, at t=5×10^6 seconds, Star 1 has a velocity ⟨-1.19×104,-8.26×103,0⟩ m/s. Define the system as Star 1 and Star 2. It is an isolated system, far from other stars. What is the momentum of the system at t=0.
