SUMMARY

The Gravitational Slingshot Effect occurs when an object passes close to a planet, allowing it to gain speed and change direction without entering orbit. This phenomenon is dictated by the object's energy level, which determines its trajectory as hyperbolic, parabolic, or elliptical. A body with excess energy follows a hyperbolic path, resulting in a significant angle between its asymptotes, enhancing the slingshot effect. Despite gravitational attraction, the object's high velocity and trajectory prevent it from being captured in orbit.

PREREQUISITES
  • Understanding of orbital mechanics
  • Familiarity with hyperbolic and elliptical trajectories
  • Knowledge of gravitational forces and energy levels
  • Basic physics principles related to motion and forces
NEXT STEPS
  • Research the mechanics of hyperbolic trajectories in orbital dynamics
  • Study the principles of gravitational assists in space missions
  • Explore the mathematical equations governing orbital mechanics
  • Investigate case studies of spacecraft utilizing the gravitational slingshot effect
USEFUL FOR

Aerospace engineers, astrophysicists, students of physics, and anyone interested in the mechanics of space travel and gravitational interactions.

Please explain Gravitational Slingshot Effect?
And when an object passes near from a planet, why it doesn't start orbiting around the planet?
Why the object is pushed away even when there is attractive force (Gravity) between object and planet ..?

Hi Ali! :smile:

Relative to a planet, a body must follow a hyperbola a parabola or an ellipse.

Which, depends on its energy.

A body with too much energy will follow a hyperbola, which means that its directions at "+∞" and "-∞" (which will be along asymptotes of the hyperbola) will be different … the closer it goes to the planet, the greater the angle between the asymptotes, and so the greater the "slingshot" effect. :wink:
 
Thanks Dear.
Please also explain that why the object doesn't orbit around the planet...?
Which force(s) pushes it away from the planet even when Gravitational Attraction is present between the object and the planet.

The wikipedia article should help you:
