The Sun's center is at one focus of Earth's orbit. How far from this focus is the other focus, (a) in meters and (b) in terms of the solar radius, `6.96 xx 10^8` m? The eccentricity is 0.0167, and the semimajor axis is `1.50 xx 10^11` m.

Explanation

To solve the problem, we need to find the distance between the two foci of the Earth's elliptical orbit around the Sun. We will use the given values of eccentricity (e) and semi-major axis (a) to calculate this distance.

### Step-by-Step Solution:

1. **Understanding the Ellipse**:
An ellipse has two foci. The distance between the two foci (F1 and F2) can be calculated using the formula:
\[
\text{Distance between foci} = 2c
