   University essay from KTH/Rymdteknik

   Author : Ignacio Santos; [2020]
   Keywords : B-Plane; Gravity assist maneuver; Interplanetary orbit transfer; Oberth effect; Periapsis; Simulation model; Space exploration; Trajectory planning.;

   Abstract : This thesis takes a closer look at the complex maneuver known as gravity assist, a popular method of interplanetary travel. The maneuver is used to gain or lose momentum by flying by planets, which induces a speed and direction change. READ MORE

3. 2. Hunting for Planet Nine by its perturbations on the Main Asteroid Belt

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Albin Jonsson; [2019]
   Keywords : Planet Nine; Main Asteroid Belt; Perturbations; evection resonance; libration; Physics and Astronomy;

   Abstract : In recent years, scientists have found unconfirmed evidence for a ninth planet in the solar system at a very wide orbit. The parameters for this planet are poorly constrained. Current estimates mostly come from the effect the planet has on trans-neptunian objects. READ MORE
