Mercury

• C.

Earth

• D.

Pluto

B. Mercury
Explanation
Mercury is the closest planet to the sun. It orbits the sun at an average distance of about 36 million miles. Its proximity to the sun allows it to have extremely high temperatures, reaching up to 800 degrees Fahrenheit during the day. Mercury is also the smallest planet in our solar system. Its close proximity to the sun makes it difficult to observe from Earth, and it can only be seen during certain times of the year and under specific conditions.

B. The Moon does not produce its own light
C. The moon is 1/4 the size of the Earth
D. There is no water on the Moon
E. The temperature on the Moon can get very hot and very cold at times
Explanation
The Moon is a satellite that revolves around the Earth, which means it orbits the Earth. It does not produce its own light but reflects the light of the Sun, which is why we see different phases of the Moon. The Moon is approximately 1/4 the size of the Earth, making it much smaller in comparison. There is no water on the Moon, as it has a very thin atmosphere and low gravity. The temperature on the Moon can vary greatly, reaching extremely hot temperatures during the day and extremely cold temperatures at night due to its lack of atmosphere to regulate heat.
