If an astronomer claims to have discovered an object with a very eccentric orbit, what best describes the orbital trajectory of the object?

Explanation:

It would look like  a squashed oval.

An celestial object's orbital eccentricity is a dimensionless factor which specifies the extent through which its trajectory  about another body detracts from a complete circle. A measure of 0 is a circular orbit, numbers between 0 and 1 generate an elliptic orbit, a parabolic escaping orbit and a hyperbola for value greater than 1. For values far greater than one  it looks like  a squashed oval.

speed = 20/2 = 10 m/s

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
