Good day, in that little head tower here. Can you think you made a metal? Ha, see if you can out metal this monster. Ball metal, over 200 kilometres across. Let's go check out 16 psyche. This is the first time I've ever seen a metal. I've never seen a metal. I've never seen a metal. I've never seen a metal. I've never seen a metal. I've never seen a metal. I've never seen a metal. Yes sir, here we are. Welcome to 16 psyche. This place is a statue or a few racists. They are covered in 1852 by the Italian astronomer Anabali Decursp看essar. 16 sigma is a big 4,看看 200 kilometres. to be more precise. I'll fly about 10% of the surface to stream a silicate rock, much as you'd find here on Good Old Earth. So this ball of 1012lp comprises nearly 1% of the mass within the asteroid ball where it lives. It actually lies roughly half way between Jupiter and Mars, about 3.3a even to Sun. What's an AU? AU is a very common astronomical term. It means astronomical units. One astronomical unit is defined as the distance between Earth and the Sun. This is about 93 million miles of 150 million kilometers. At 3.3a you, this means 16-psychic lies some 300 and 8 million kilometers from the Sun. One of those is really special about this metal asteroid. Two things. First of all, 16-psychic is extremely valuable. All of that iron and nickel within has been valued at over 10,000 quadrillion dollars. That's just nuts. Obviously that means a lot of folks would love the wine of all that metal. A whole bunch of companies are sprung up in the last few years looking to cash in on asteroids. The next big thing. Now personally, I don't care about all that. You want to know what's really cool about 16-psychic? It's the exposed core of a long dead proto planet. The remains of a tiny world, maybe 500 kilometers in diameter. This tiny planetoid took its beating during the late heavy bombardment some 4 billion years ago. In fact, this nameless world may have been impacted by other large bodies up to 8 times. This pounding shattered the outer crust, standing scattered fragments out into the newly forming asteroid belt and leaving behind an exposed core. Scientists would love to study 16-psychic because they can teach us a lot about planet formation and our planet's work, including our own. Just look at it. Imagine walking on the core of a planet. 16-psychic gives us an opportunity to see into our own world. It's like a time capsule, a snapshot of a newly forming planet frozen in time forever. This is the real value of 16-psychic, this frozen soul. Let's take one last look and imagine actually being there. I hope you've enjoyed Astrobiological Today. If you have, as described.
