Test: Solar System - 1 - Class 1 MCQ

Earth is the third planet from the Sun.

The order of the planets from the Sun is:

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

So the correct answer is:

2. Earth

The correct order is Mars(IV), Mercury(III), Jupiter(I), Earth(V), Venus(II). Jupiter is the largest planet.

Mars is often referred to as the "Red Planet" due to its reddish appearance, which is caused by iron oxide (rust) on its surface. Mercury is not commonly called the "Red Planet."

Saturn is known for its spectacular and prominent ring system, composed of ice particles, dust,etc whereas Mercury, Mars and Venus do not have any ring systems, making Saturn the only planet in this list with rings.

Uranus has the coldest atmosphere of any of the planets in the solar system, even though it is not the most distant from the sun. That's because Uranus has little to no internal heat to supplement the heat from the sun.

Jupiter is the largest planet in our solar system. It is more than 11 times the diameter of Earth and has a mass more than 300 times that of Earth. Saturn, Uranus, and Mars are smaller than Jupiter.

Mercury is the smallest planet in our solar system. It is slightly larger than Earth's moon. Uranus and Saturn are larger than Mercury, and Mars is also larger but still smaller than Earth.

Venus is the hottest planet in our solar system due to its thick atmosphere, which creates a greenhouse effect. The average surface temperature on Venus is around 462 degrees Celsius (864 degrees Fahrenheit), making it hotter than Mercury, which is closer to the sun.

Neptune is the farthest planet from the sun in our solar system. Uranus is the seventh planet from the sun, Jupiter is the fifth planet from the sun, and Mercury is the closest planet to the sun.

• Mercury is the first planet in our solar system, orbiting closest to the Sun.
• It has a highly elliptical orbit, completing a full revolution around the Sun in about 88 Earth days.
• Due to its proximity to the Sun, Mercury experiences extreme temperatures, ranging from very hot during the day to freezing at night.
• This small, rocky planet lacks a substantial atmosphere, which contributes to its temperature variations.
