Asteroid 15 Eunomia Distance
The distance of Asteroid 15 Eunomia from Earth is currently 315,921,616 kilometers, equivalent to 2.111806 Astronomical Units. Light takes 17 minutes and 33.8011 seconds to travel from Asteroid 15 Eunomia and arrive to us.
The following chart shows the distance of Asteroid 15 Eunomia 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 15 Eunomia from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Asteroid 15 Eunomia to Earth
Between January 2013 and December 2100 the closest approach of Asteroid 15 Eunomia to Earth happens on Sat Oct 24 2071 at a distance of 1.19032029 Astronomical Units, or 178,069,381 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 15 Eunomia brightness
The current visual magnitude of Asteroid 15 Eunomia is 9.73.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 15 Eunomia, 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 15 Eunomia 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 15 Eunomia 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 15 Eunomia 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.
