Asteroid (NEO) 2021 JZ5

Above the horizon.  Rise: 6:50 | Tran: 12:36 | Set: 18:22
Alt: 27.20°   Az: 137.01°   Direction: South-East
Please note: this information pertains to a Near-Earth Object (NEO). During close approaches, our current computational model is not able to provide an accurate position, due to the high speeds of these objects. We plan to refine our algorithms to improve accuracy in the future. JPL Horizons can compute precise positions in these situations.

Asteroid (NEO) 2021 JZ5 is in the constellation of Aquarius, at a distance of 254,451,743.0 kilometers from Earth. The current Right Ascension is 22h 30m 37s and the Declination is -02° 43’ 41” (apparent coordinates). The magnitude of Asteroid (NEO) 2021 JZ5 is 29.66 (data provided by JPL Horizons).

Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2021 JZ5, 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.
