Asteroid 3 Juno Distance from Earth

The distance of Asteroid 3 Juno from Earth is currently 573,584,989 kilometers, equivalent to 3.834179 Astronomical Units. Light takes 31 minutes and 53.2736 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 current visual magnitude of Asteroid 3 Juno is 11.51.

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

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, 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.

Visualization of Asteroid 3 Juno Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Asteroid 3 Juno with respect of the Sun and the orbits of the major planets. The position of Asteroid 3 Juno and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
