I'm not really looking to have it all solved for me... if someone could just point me in the correct direction or give me a formula, it would be greatly appreciated. 
An asteroid has a perihelion distance of 0.21 A.U. and an orbital eccentricity of 0.66. What is its semi-major axis and aphelion distance from the Sun? [In AU]
Thanks so much.
