Asteroid 3 Juno Distance
The distance of Asteroid 3 Juno from Earth is currently 465,323,851 kilometers, equivalent to 3.110498 Astronomical Units. Light takes 25 minutes and 52.1533 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 1.03592987 Astronomical Units, or 154,972,902 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 3 Juno brightness
The current visual magnitude of Asteroid 3 Juno is 10.25.
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
Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London
Today's Asteroid 3 Juno rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):
The rise and set times are defined as the time at which the upper limb of Asteroid 3 Juno 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.
