Asteroid 5 Astraea Distance from Earth
The distance of Asteroid 5 Astraea from Earth is currently 286,559,971 kilometers, equivalent to 1.915535 Astronomical Units. Light takes 15 minutes and 55.8612 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 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
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.
