Asteroid 3 Juno
Asteroid 3 Juno is currently in the constellation of Serpens. The current Right Ascension of Asteroid 3 Juno is 17h 23m 40s and the Declination is -12° 14’ 40” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current magnitude of Asteroid 3 Juno is 11.23 (JPL).
Summary of key facts about Asteroid 3 Juno [tip: you can also create a Quick Access page for this data if you access it frequently and would like to have a simpler view]:
- 3 Juno is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the East-South-East direction at an altitude of 4° above the horizon.
- Given its current magnitude, 3 Juno is visible with the help of a binocular with a 70-80mm aperture or a small telescope.

Asteroid 3 Juno Distance from Earth
The distance of Asteroid 3 Juno from Earth is currently 531,722,290 kilometers, equivalent to 3.554344 Astronomical Units. Light takes 29 minutes and 33.6346 seconds to travel from Asteroid 3 Juno and arrive to us.
The following chart shows the distance of Asteroid 3 Juno 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 3 Juno from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Asteroid 3 Juno to Earth
Between January 2013 and December 2100, the closest approach of Asteroid 3 Juno to Earth happens on Fri Nov 16 2018 at a distance of 1.035930 Astronomical Units, or 154,972,893 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 3 Juno brightness
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 3 Juno, 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 3 Juno rise and set times
The rise and set times are defined as the time at which the upper limb of Asteroid 3 Juno 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.
