Which of these planets of our solar system is hotter than the Earth?

Options

A. Mars
B. Venus
C. Neptune
D. Jupiter

Answer

To determine which planet in our solar system is hotter than Earth, we can follow these steps:

### Step 1: Identify the planets in the question
The planets mentioned are Mercury, Venus, Neptune, and Jupiter.

### Step 2: Understand the temperature of Earth
Earth has an average surface temperature of about 15 degrees Celsius (59 degrees Fahrenheit).

### Step 3: Compare the average temperatures of the listed planets
- **Mercury**: Although it is the closest planet to the Sun, it has extreme temperature variations. During the day, it can reach up to 430 degrees Celsius (800 degrees Fahrenheit), but at night, it can drop to -180 degrees Celsius (-290 degrees Fahrenheit). The average temperature is around 167 degrees Celsius (332 degrees Fahrenheit).

- **Venus**: Venus has a thick atmosphere composed mainly of carbon dioxide, which creates a strong greenhouse effect. The average surface temperature on Venus is about 467 degrees Celsius (872 degrees Fahrenheit), making it the hottest planet in our solar system.

- **Neptune**: Neptune is a gas giant and is very far from the Sun. Its average temperature is around -214 degrees Celsius (-353 degrees Fahrenheit), which is much colder than Earth.

- **Jupiter**: Jupiter, another gas giant, has an average temperature of about -108 degrees Celsius (-162 degrees Fahrenheit), which is also colder than Earth.

### Step 4: Determine which planet is hotter than Earth
From the comparison:
- Mercury has a higher average temperature than Earth but has extreme variations.
- Venus has a significantly higher average temperature than Earth due to its thick atmosphere and greenhouse effect.
- Neptune and Jupiter are both much colder than Earth.

### Conclusion
The planet that is hotter than Earth is **Venus**.
