Given the following elliptical path of a planet around the sun, note the three points on the orbit as P1, P2, and P3. Measure the distance of each point to the two foci and write them in the table on the next page. Add up the two distances for each point.

**(A) Where is the sun on the ellipse diagram?**

---

**Diagram Description:**  
The diagram shows an elliptical orbit with three marked points: P1, P2, and P3. The ellipse has a major axis and a minor axis. The two foci are labeled as F1 and F2, positioned along the major axis.

- **P1** is located on the left side of the elliptical orbit.
- **P2** is located on the right side of the elliptical orbit.
- **P3** is located at the bottom of the elliptical orbit.

The major axis is horizontal, and the minor axis is vertical. The positions of the foci (F1 and F2) are symmetric along the major axis.

---

**Note:**
To complete this activity, measure the distances from each point (P1, P2, P3) to the foci (F1 and F2) using appropriate tools and record the distances. Then sum the individual distances for each point to understand the properties of elliptic orbits according to Kepler's First Law.

#### Kepler’s Second Law

Write **Kepler’s Second Law** in your own words:
\[ \underline{\hspace{200pt}} \]

---

#### Diagram Explanation:

The diagram provided illustrates **Kepler's Second Law**—**the law of equal areas**. 

1. **Sun** is positioned at one of the foci of an elliptical orbit.
2. The **Planet** moves along this elliptical orbit around the Sun.
3. The segments labeled **A** through **L** represent different time intervals.
4. Each shaded area (e.g., **Sector AL**, **Sector BI**, etc.) shows the area covered by the line joining the planet and the Sun as the planet moves around its orbit within equal time intervals.
5. According to Kepler’s Second Law, these shaded areas are equal.
