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.
16 Psyche is the heaviest known M-type asteroid with a mean diameter of 220 kilometres (140 mi), and may be an exposed iron core of a protoplanet, [21] the remnant of a violent collision with another object that stripped off its mantle and crust. Recent studies show that it is "a mixed metal and silicate world". [22]
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.
A new simulation looked at what would happen if the Earth collided with an asteroid with a diameter of around 500 metres, roughly the same as Bennu, a real rock that has been studied in great ...
NASA has launched a spacecraft to study the metal asteroid Psyche to determine whether it’s the exposed core of an early planetary building block.
Asteroid Psyche measures roughly 173 miles (279 km) across at its widest point and resides on the outer fringes of the main asteroid belt between the planets Mars and Jupiter.
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. [8] 511 Davida could have $27 quadrillion worth of minerals and resources. [9] NASA estimates that between 1.1 and 1.9 million asteroids in the asteroid belt are larger than 1 kilometer in diameter. Millions are smaller.
An independent review board gave NASA’s Psyche mission the green light and its seal of approval following a scathing review in 2022. The Psyche mission, which will head to the asteroid belt, was ...
