Educational worksheet illustrating the solar system with planets in order from the Sun, including facts about the solar system and a diagram of planetary orbits.

Problem Description:

The image provided is a worksheet from the "Ministry of Education" for Grade 5 students, focusing on the topic Earth and Space: The Solar System. The task involves understanding the structure and components of the solar system, including the planets, their order from the Sun, and key facts about the solar system.

Key Information Provided in the Image:

1. Definition of the Solar System:
- The solar system consists of the Sun and everything that orbits it.
- This includes:
- Eight planets and their moons.
- Dwarf planets.
- Countless asteroids, comets, and other small icy objects.
- The Sun is a star and is located at the center of the solar system.

2. Order of Planets from the Sun:
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune

3. Fact About Life:
- The only planet with life in our solar system is Earth.

4. Visual Representation:
- A diagram of the solar system showing the orbits of the planets around the Sun.

Task Analysis:

The task appears to be an informational exercise where students are expected to:
- Understand the definition of the solar system.
- Memorize and recall the order of the planets from the Sun.
- Identify key facts about the solar system, such as the central role of the Sun and the uniqueness of Earth as the only known habitable planet.

Solution Explanation:

#### Step 1: Understanding the Solar System
The solar system is a collection of celestial bodies that orbit the Sun. These include:
- Planets: Eight major planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune).
- Dwarf Planets: Smaller bodies like Pluto.
- Moons: Natural satellites orbiting planets.
- Asteroids: Rocky objects mostly found in the asteroid belt between Mars and Jupiter.
- Comets: Icy bodies that orbit the Sun and sometimes develop visible tails when they approach the Sun.
- Other Objects: Small icy bodies and debris.

#### Step 2: Order of Planets from the Sun
The planets are arranged in a specific order based on their distance from the Sun:
1. Mercury: Closest to the Sun, very hot due to its proximity.
2. Venus: Second closest, has a thick atmosphere and is also very hot.
3. Earth: Third from the Sun, the only known planet with life.
4. Mars: Fourth from the Sun, often called the "Red Planet."
5. Jupiter: Fifth from the Sun, the largest planet in the solar system.
6. Saturn: Sixth from the Sun, famous for its prominent ring system.
7. Uranus: Seventh from the Sun, known for its tilted axis.
8. Neptune: Eighth from the Sun, the farthest major planet.

#### Step 3: Key Facts About the Solar System
- Central Role of the Sun: The Sun is the primary source of energy in the solar system. It provides light and heat necessary for life on Earth.
- Uniqueness of Earth: Earth is the only planet in the solar system known to support life. This is due to factors such as its distance from the Sun, presence of liquid water, and suitable atmospheric conditions.

#### Step 4: Visual Representation
The diagram in the image shows the relative positions of the planets around the Sun. Each planet is depicted in its respective orbit, illustrating the vast distances between them. The Sun is shown at the center, emphasizing its central role.

Final Answer:

The solution to the problem involves:
1. Understanding the Definition: The solar system is centered around the Sun and includes planets, dwarf planets, moons, asteroids, comets, and other objects.
2. Recalling the Order of Planets: The order from the Sun is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
3. Key Facts:
- The Sun is the central star.
- Earth is the only known habitable planet.
- The solar system contains diverse objects beyond just the planets.

Thus, the task is completed by reinforcing these concepts and ensuring the student understands the structure and significance of the solar system.

Final Answer Boxed:
\[
\boxed{\text{The solar system consists of the Sun and its orbiting bodies, with planets ordered as Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Earth is the only known habitable planet.}}
