Educational worksheet for labeling planets in the solar system.

Problem Description:

The task is to label the planets in the solar system as shown in the image and identify the galaxy in which our solar system resides.

Solution:

#### Step 1: Identify the Planets
The image shows a sequence of celestial bodies representing the planets of the solar system. The order of the planets from the Sun (not shown but implied) is as follows:

1. Mercury: The smallest planet, closest to the Sun.
2. Venus: The second planet from the Sun, known for its thick atmosphere and high surface temperature.
3. Earth: The third planet from the Sun, the only known planet to support life.
4. Mars: The fourth planet from the Sun, often called the "Red Planet" due to its reddish appearance.
5. Jupiter: The largest planet in the solar system, a gas giant with a prominent Great Red Spot.
6. Saturn: The sixth planet from the Sun, famous for its extensive ring system.
7. Uranus: The seventh planet from the Sun, an ice giant with a unique axial tilt.
8. Neptune: The eighth planet from the Sun, another ice giant known for its strong winds.

#### Step 2: Label the Planets
Based on their relative sizes and positions in the image, we can label them as follows:

- Closest to the Sun (far left): Mercury
- Second from the Sun: Venus
- Third from the Sun: Earth
- Fourth from the Sun: Mars
- Fifth from the Sun: Jupiter
- Sixth from the Sun: Saturn
- Seventh from the Sun: Uranus
- Eighth from the Sun: Neptune

#### Step 3: Identify the Galaxy
The solar system is part of the Milky Way Galaxy. This is a spiral galaxy containing billions of stars, including our Sun.

Final Answer:

1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

This solar system is in the Milky Way Galaxy.
