CNN News:小行星16 Psyche的估值10000万亿美元

2020-12-10来源:和谐英语

What is 16 Psyche?
Is it a grunge band, a game show, a Pavlovian theory, or an asteroid?
It's a bird, it's a plane, it's an asteroid that was discovered in 1852 and named for a figure in Greek mythology.
Ten thousand quadrillion dollars. Now that I have your attention, we're talking about the possible, estimated, hypothetical value of an asteroid. But, Carl, you may be thinking, it's a rock.

You're right. A rock named Asteroid 16 Psyche is about the length of Massachusetts. Scientists have been studying it through pictures gathered by the Hubble space telescope, and they published new findings in the Planetary Science Journal. They don't know exactly what it's made of, but they think that Asteroid 16 Psyche could be iron and nickel.
If it is, they say a piece of iron that big would be worth more than all the economies on earth combined.
OK. So, let's go get it. Well, not so fast, Han Solo.
The asteroid is three times farther from the sun than we are. NASA hopes to send a probe there in 2022. Researchers hope it gathers some secrets of the universe.
