A: Mr. Liu, can I ask you some questions about Mars?

B: Sure, go ahead.

A: Is Mars hot?

B: Mars might look red-hot. But don't let its color fool you. Mars is much farther away from the sun than Earth. So it gets less light and heat.

A: Why "Mars"?

B: Mars takes its name from the Roman god of war (罗马战神). In China, the red color makes people think of fire. So they call the planet "fire star".

A: Are there Martians on Mars?

B: Unluckily, we haven't found any "people" on Mars yet. They are kind of like Santa Clause. Nobody can see them, but many people believe they are real.

A: Will we lose weight on Mars?

B: Living on Mars could be good in many ways. For example, you might not need to go on a diet to lose weight. If you weigh 50kg on Earth, you will only weigh 19kg on Mars. This is because the surface gravity (表面重力) on Mars is only about 38 percent of that on Earth. Do you want to know your weight on Mars? Just multiply your weight by 0.38. That's it.

A: Thank you. We know a lot about Mars now.

B: You're welcome.
