The distance of Asteroid (NEO) 2021 DR from Earth is currently 228,204,540 kilometers, equivalent to 1.525453 Astronomical Units. Light takes 12 minutes and 41.2084 seconds to travel from Asteroid (NEO) 2021 DR and arrive to us.
The following chart shows the distance of Asteroid (NEO) 2021 DR 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.
Closest Approach of Asteroid (NEO) 2021 DR to Earth
During the next 10 years, the closest approach of Asteroid (NEO) 2021 DR to Earth happens on Wed Feb 11 2032 at a distance of 0.005066 Astronomical Units, or 757,889 kilometers:
Asteroid (NEO) 2021 DR Brightness
The current visual magnitude of Asteroid (NEO) 2021 DR is 29.72.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2021 DR, 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.
