Asteroid 18 Melpomene Distance from Earth

The distance of Asteroid 18 Melpomene from Earth is currently 392,232,624 kilometers, equivalent to 2.621913 Astronomical Units. Light takes 21 minutes and 48.3472 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 0.81239808 Astronomical Units, or 121,533,023 kilometers:

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

Asteroid 18 Melpomene brightness

The current visual magnitude of Asteroid 18 Melpomene is 11.06.

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

Today's Asteroid 18 Melpomene 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 18 Melpomene 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.
