Asteroid 5 Astraea Distance from Earth

The distance of Asteroid 5 Astraea from Earth is currently 495,564,794 kilometers, equivalent to 3.312646 Astronomical Units. Light takes 27 minutes and 33.0262 seconds to travel from Asteroid 5 Astraea and arrive to us.

The following chart shows the distance of Asteroid 5 Astraea 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 5 Astraea from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Asteroid 5 Astraea to Earth

Between January 2013 and December 2100, the closest approach of Asteroid 5 Astraea to Earth happens on Mon Feb 15 2016 at a distance of 1.095425 Astronomical Units, or 163,873,203 kilometers:

NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Asteroid 5 Astraea brightness

The current visual magnitude of Asteroid 5 Astraea is 12.78.

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 5 Astraea, 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 5 Astraea rise and set times

Today's Asteroid 5 Astraea 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 5 Astraea 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.
