Distance from Earth
The distance of Near Earth Object 2021 PJ1 from Earth is currently
The following graph shows the distance of Near Earth Object 2021 PJ1 from Earth as a function of time. In the chart the distance is measured in Astronomical Units and the data is sampled with an interval of 1 day.
Note: The values in this chart may not be entirely accurate around the time of closest approach for objects passing very close to Earth at high speed (e.g., Near-Earth Objects).
Closest Approach to Earth
During the next 10 years, the closest approach of Near Earth Object 2021 PJ1 to Earth will happen on Friday 15 August 2025 at a distance of 0.011195 Astronomical Units, or 1,674,743 kilometers:
Light Curve
The following chart shows the light curve of Near Earth Object 2021 PJ1, i.e., its apparent magnitude as a function of time. The curve is calculated using the latest ephemerides provided by JPL Horizons. The magnitude data is sampled with the interval of 2 days. Because of this sampling, inaccuracies may occur for objects that have large variations of brightness over a few days. For comets, large discrepancies can arise between the calculated brightness and the observations due to their highly dynamic, and not always precisely predictable, behavior.
