Asteroid 16 Psyche
Asteroid 16 Psyche is an interesting object in the asteroid belt because it is believed to have a high concentration of metallic iron and nickel in its composition, making it one of the largest known metallic asteroids in the solar system. It was discovered on March 17, 1852, by the Italian astronomer Annibale de Gasparis, who named it after Psyche, a figure in Greek mythology who represents the soul. Psyche is approximately 226 kilometers in diameter and orbits the Sun at a distance of about 3 astronomical units (AU), with an orbital period of about 5.5 years. The asteroid has been identified as a potential target for future space exploration, including NASA's Psyche mission.
Asteroid 16 Psyche is currently in the constellation of Capricornus, at a distance of 431,367,056 kilometers from Earth.

Asteroid 16 Psyche Distance from Earth
The distance of Asteroid 16 Psyche from Earth is currently 431,367,056 kilometers, equivalent to 2.883511 Astronomical Units. Light takes 23 minutes and 58.8856 seconds to travel from Asteroid 16 Psyche and arrive to us.
The following chart shows the distance of Asteroid 16 Psyche from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 16 Psyche from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 16 Psyche to Earth
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 16 Psyche to Earth happens on Fri Nov 24 1905 at a distance of 1.641628 Astronomical Units, or 245,584,060 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 16 Psyche Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 16 Psyche, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
