Asteroid 3 Juno Orbit Diagram
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!

Distance of Asteroid 3 Juno from Earth
The following chart shows the distance of Asteroid 3 Juno from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval.
The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 3 Juno is also available as a real time updated value in the Live Position and Data Tracker.
Light Curve of Asteroid 3 Juno
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.
