21 minutes and 43.5964 seconds

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.

Distance of Asteroid 16 Psyche from Earth between January 2013 and December 2100

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 January 2013 and December 2100 the closest approach of Asteroid 16 Psyche to Earth happens on Mon Aug 17 2099 at a distance of 1.66470724 Astronomical Units, or 249,036,660 kilometers:

NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Asteroid 16 Psyche brightness

The current visual magnitude of Asteroid 16 Psyche is 11.06.


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.

Asteroid 16 Psyche rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's Asteroid 16 Psyche rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 106.1°
Max altitude: 22.4°
Azimuth: 253.9°
Asteroid 16 Psyche is above the horizon from Greenwich, United Kingdom

The rise and set times are defined as the time at which the upper limb of Asteroid 16 Psyche touches the horizon, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
