Asteroid 18 Melpomene Distance
The distance of Asteroid 18 Melpomene from Earth is currently 198,187,445 kilometers, equivalent to 1.324801 Astronomical Units. Light takes 11 minutes and 1.0822 seconds to travel from Asteroid 18 Melpomene and arrive to us.
The following chart shows the distance of Asteroid 18 Melpomene 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 18 Melpomene from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Asteroid 18 Melpomene to Earth
Between January 2013 and December 2100 the closest approach of Asteroid 18 Melpomene to Earth happens on Thu Oct 6 2089 at a distance of 0.81239810 Astronomical Units, or 121,533,026 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 18 Melpomene brightness
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 18 Melpomene, 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 18 Melpomene rise and set times
The rise and set times are defined as the time at which the upper limb of Asteroid 18 Melpomene 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.
