Let the length of aphelion be

Let the length of semi major axis of the elliptical path be

As we know that semi major axis is the average of perihelion and aphelion.
So,
![s=(p+a)/(2) =(1558.14)/(2)=779.07](https://img.qammunity.org/2020/formulas/physics/high-school/w0a6clxi27hcfqomz1t2lnd847bc1yeey1.png)

![e=1-(p)/(s)=1-(741.52)/(779.07)=0.048](https://img.qammunity.org/2020/formulas/physics/high-school/9qlofb8yrjcobasb626sk8pnl6hd2rqwjz.png)
