Projectile Trajectory

Can a Projectile trajectory be a Ellipse, Hyperbola
or any other Geometrical shape than parabola?

Thanks & Regards,

Actually planetary orbits take the shape of an ellipse. Some asteroids come into the Solar system going very fast and wind up being in hyperbolic "orbits." (They leave the Solar system, which is why orbit isn't really a good word.)

It turns out that, depending on initial conditions that the path of a body can travel a path given by one of the conic sections.

You know, I would love to know why you keep posting links to the most basic of things. For example, you once posted a wikipedia link about what a mountain is and in this one you gave a link to what a particle is. I would have expected to see a link about orbital motions or something more relevant.
