Asteroid (NEO) 2021 XE Distance from Earth
The distance of Asteroid (NEO) 2021 XE from Earth is currently 156,532,230 kilometers, equivalent to 1.046353 Astronomical Units. Light takes 8 minutes and 42.1353 seconds to travel from Asteroid (NEO) 2021 XE and arrive to us.
The following chart shows the distance of Asteroid (NEO) 2021 XE 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 XE to Earth
During the next 10 years, the closest approach of Asteroid (NEO) 2021 XE to Earth happens on Wed Dec 10 2031 at a distance of 0.009612 Astronomical Units, or 1,437,882 kilometers:
Asteroid (NEO) 2021 XE Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2021 XE, 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.
