16 Psyche (/ ˈ s aɪ k iː / SY-kee) is a large M-type asteroid, which was discovered by the Italian astronomer Annibale de Gasparis, on 17 March 1852 and named after the Greek goddess Psyche. [10] The prefix "16" signifies that it was the sixteenth minor planet in order of discovery.
Asteroid 16 Psyche is the heaviest known M-type asteroid, and may be an exposed iron core of a protoplanet, the remnant of a violent collision with another object that stripped off its mantle and crust. On January 4, 2017, the Psyche mission was selected for NASA's Discovery #14 mission. [9] [10]
The numbered-circle convention was quickly adopted by astronomers, and the next asteroid to be discovered (16 Psyche, in 1852) was the first to be designated in that way at the time of its discovery. However, Psyche was given an iconic symbol as well, as were a few other asteroids discovered over the next few years.
With approximately as much iron as the world produces in 100,000 years, 16 Psyche is one such asteroid worth approximately $10 quintillion in metallic iron and nickel. [7] NASA is planning a mission for October 10, 2023 for the Psyche orbiter to launch and get to the asteroid by August 2029 to study.

Scientists wonder whether this asteroid, named 16 Psyche, could be an exposed core of an early planet, once possibly as large as Mars, that lost its rocky outer layers after countless collisions ...
Psyche — orbiter to 16 Psyche, the most massive metallic asteroid in the asteroid belt, thought to be exposed iron core of a protoplanet. [78] Selected as one of five finalists in September 2015. Kuiper Telescope — this would target multiple objects, including the giant planets, their satellites, and small bodies with a 1.2-meter diameter ...
