While researching a topic, a student has taken the following notes:
- Kepler's first law of planetary motion states that the orbit of a planet around the Sun is an ellipse.
- The law also states that, in an elliptical orbit, the object being orbited is one of the ellipse's foci.
- Kepler's laws of planetary motion also apply to natural satellites (e.g., moons).
- Europa is a moon of Jupiter that orbits the planet in 3.55 Earth days on average.
- Europa's orbit is elliptical.
