There are probably two million asteroids in our solar system. The reason that psyche is unique is that it is metal rich. It's believed that it may be a remnant core of an early planetesma. One of the ingredients that went into making our Earth and one that we cannot see any other way. And it would be the first metal object that humankind is ever visited. Studying the evolution of a planetary body is a detective story. I think the only thing we know is it's not going to look like what we think it's going to look like. And it's going to be really interesting, whatever we find. Space is always more amazing than we can imagine with our minds.
