Asteroid 2018 AJ Distance
The distance of Asteroid 2018 AJ from Earth is currently 245,796,931 kilometers, equivalent to 1.643051 Astronomical Units. Light takes 13 minutes and 39.8903 seconds to travel from Asteroid 2018 AJ and arrive to us.
The following chart shows the distance of Asteroid 2018 AJ 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 2018 AJ from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Asteroid 2018 AJ to Earth
Between January 2013 and December 2100 the closest approach of Asteroid 2018 AJ to Earth happens on Wed Jan 24 2018 at a distance of 0.01203514 Astronomical Units, or 1,800,431 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 2018 AJ brightness
The current visual magnitude of Asteroid 2018 AJ is 28.07.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 2018 AJ, 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 2018 AJ 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 2018 AJ 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 2018 AJ 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.
