The following chart shows the distance of Asteroid 11 Parthenope 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 11 Parthenope from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Asteroid 11 Parthenope to Earth
Between January 2013 and December 2100 the closest approach of Asteroid 11 Parthenope to Earth happens on Mon Aug 11 2081 at a distance of 1.18705014 Astronomical Units, or 177,580,174 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 11 Parthenope brightness
The current visual magnitude of Asteroid 11 Parthenope is 11.51.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 11 Parthenope, 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 11 Parthenope 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 11 Parthenope 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 11 Parthenope 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.
