Psyche is an asteroid of about 130 miles in diameter, roughly the size of Massachusetts. Scientists believe that Psyche, which is located near the outside of the main asteroid belt, about 280 million miles from the sun, may be the stripped core of a failed planet, or a planet that just never fully made it to being a planet. We'll know a lot more about Psyche in about 13 years, because a team of scientists led by Arizona State University are planning to go check it out. The mission, which received funding from NASA in January, won't launch until 2023, and it'll take seven years for the spacecraft to reach the asteroid, but the preparation has already begun, and one of the first steps was to 3D print a model of Psyche so that the team can get an idea of what it might look like before they see it for real.
