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 3200 Phaethon from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Asteroid 3200 Phaethon to Earth

Between January 2013 and December 2100, the closest approach of Asteroid 3200 Phaethon to Earth happens on Mon Dec 14 2093 at a distance of 0.021740 Astronomical Units, or 3,252,283 kilometers:

Asteroid 3200 Phaethon brightness

The current visual magnitude of Asteroid 3200 Phaethon is 17.84.


The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 3200 Phaethon, 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 3200 Phaethon rise and set times

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

Asteroid 3200 Phaethon is circumpolar and transits at 02:01 UTC (altitude: 78.8°)

The rise and set times are defined as the time at which the upper limb of Asteroid 3200 Phaethon touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
