"Wow, Max! Should we take a trip to Mercury?" Henry exclaimed.

"Absolutely, Henry! Let's go!" Sam replied.

"Henry, did you know that Mercury is the closest planet to the Sun?" Sam asked.

"Yes! It's only about 36 million miles away from the Sun. That's less than half the distance from the Earth to the Sun!" Henry replied.

As the spaceship hovered above Mercury's surface, Sam said, "Henry, it's super hot here during the day. Temperatures can reach up to 800 degrees Fahrenheit!"

"But at night," Henry added, "it gets really cold, as low as -290 degrees Fahrenheit. That's quite a swing! Imagine how difficult it would be to live here."

Henry and Sam decided to wear their special space suits that kept them cool during the scorching day and warm during the freezing night. They stepped onto the planet's rocky ground, feeling a bit like explorers on a new world.

While walking around, they spotted a small, friendly robot. "Hi there! I'm Mercury's Messenger. I was sent to gather information about this planet. Would you like to learn some fun facts?"

"Sure!" Henry and Sam said in unison.

"Mercury doesn't have an atmosphere like Earth," said the Messenger. "That's why its surface is covered in craters. The lack of air also means there's no wind, and the sky is always black, even during the day."

"Wow! That's so different from Earth," Henry said. "How long is a day on Mercury?"

The Messenger replied, "One day on Mercury lasts about 59 Earth days. But it orbits the Sun quickly, taking just 88 Earth days to complete one revolution. So, a year on Mercury is shorter than two Mercury days!"

As they approached Earth, Henry said, "Sam, we learned so much about Mercury today! It's a fascinating place, but definitely not suitable for humans to LIVE."

"You're right, Henry. But it was an incredible adventure, and I'm glad we got to explore it together," Sam replied with a smile.
