Now, let’s go through each clue and determine the correct answer.

---

1. A medium-sized rocky object orbiting the Sun.
→ This describes an asteroid.
✔ Answer: Asteroid

2. The closest planet to the Sun and the brightest target.
→ The closest planet to the Sun is Mercury, but "brightest target" might refer to Venus, which is often the brightest planet in the night sky.
However, the clue says "closest planet to the Sun", so it must be Mercury.
But note: "brightest target" may be misleading — Venus is brighter than Mercury.
Wait — actually, Venus is the brightest planet in the sky, but not the closest.
So if the clue says closest and brightest, that’s conflicting. But the key word is closest.
→ Mercury is closest to the Sun.
But "brightest target" might be a red herring or misstatement.
However, in astronomy, Venus is often called the "morning star" or "evening star" due to its brightness.
But closest = Mercury.
→ So likely intended answer is Mercury? But Venus is more commonly associated with being bright.
Let’s look at clue 11: “It is the brightest object in the sky except for the Sun and the Moon.” That’s Venus.
So clue 2: “closest” = Mercury, but “brightest target” doesn’t fit.
Maybe it’s a typo? Or perhaps it means Venus is the brightest *planet* seen from Earth.
But the clue says closest and brightest — so contradiction.
Actually, Mercury is closest, but not the brightest.
So perhaps the clue should be: "The planet closest to the Sun."
But as written, it's ambiguous.
However, since Mercury is the only one that fits "closest," we'll go with that.
✔ Answer: Mercury

3. The largest planet; more than twice as massive as all the other planets combined.
→ This is clearly Jupiter.
✔ Answer: Jupiter

4. The largest object in the solar system.
→ The Sun is the largest object in the solar system.
✔ Answer: Sun

5. This planet probably got its name due to its red color and is sometimes referred to as the Red Planet.
→ Mars is known as the Red Planet.
✔ Answer: Mars

6. The only planet whose English name does not derive from Greek/Roman mythology.
→ Most planets are named after Roman/Greek gods:
- Mercury, Venus, Mars, Jupiter, Saturn, Uranus (Greek), Neptune (Roman)
- Earth is the only one not derived from mythology.
(Note: "Earth" comes from Old English, not mythological names.)
✔ Answer: Earth

7. The smallest planet and farthest from the Sun.
→ Pluto was once considered the ninth planet, and it's small and farthest.
But now classified as a dwarf planet. Still, in many educational contexts, especially older ones, it's still used.
Also, Pluto is the smallest of the former planets and farthest.
✔ Answer: Pluto

8. A planet-like blue color is the result of absorption of red light by methane in the atmosphere.
→ Uranus has a blue-green color due to methane in its atmosphere.
✔ Answer: Uranus

9. A bowl-shaped depression formed by the impact of a meteoroid.
→ This is a crater.
✔ Answer: Crater

10. The second largest planet with many rings.
→ Saturn is known for its prominent rings and is the second-largest planet.
✔ Answer: Saturn

11. It is the brightest object in the sky except for the Sun and the Moon.
→ Venus is the brightest planet in the night sky.
✔ Answer: Venus

12. Named after the Roman god of the sea.
→ Neptune is named after the Roman god of the sea.
✔ Answer: Neptune

13. The only natural satellite of Earth.
→ The Moon is Earth's only natural satellite.
✔ Answer: Moon

✔ Final Answers:

1. Asteroid
2. Mercury *(Note: though not the brightest, it is closest)*
3. Jupiter
4. Sun
5. Mars
6. Earth
7. Pluto
8. Uranus
9. Crater
10. Saturn
11. Venus
12. Neptune
13. Moon

🔍 Explanation Summary:

- Clue #2 is slightly problematic because Mercury is closest to the Sun, but Venus is the brightest planet. However, since the clue specifies "closest," Mercury is the correct answer.
- Clue #7 refers to Pluto, which is no longer a planet but was historically considered the ninth and farthest.
- Clue #9 refers to a crater, which is a common feature on moons and planets.
- Clue #13 refers to the Moon, Earth's only natural satellite.
