Distance from Earth
The distance of Asteroid (NEO) 2021 BB from Earth is currently
The following chart shows the distance of Asteroid (NEO) 2021 BB 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
During the next 10 years, the closest approach of Asteroid (NEO) 2021 BB to Earth happens on Mon Jan 14 2030 at a distance of 0.012004 Astronomical Units, or 1,795,775 kilometers:
Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2021 BB, 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.
