Question

A planet revolves around the sun in an orbit with an eccentricty = 0.99, the orbit is:

• A. almost circular
• B. almost elliptical
• C. almost straight
• D. parabolic

Answer 1

The correct option is D parabolic

Eccentricity of a circle $=0$

Eccentricity of an ellipse $=$ between $0$ to $1$

Eccentricity of a hyperbola $>1$

Eccentricity of a straight line $=$ infinite

Eccentricity of a parabola $=1$

So, the orbit will be parabola as $[0.99\sim 1]$
