Alt: -24.62°   Az: 298.13°   Direction: West-North-West
Please note: this information pertains to a Near-Earth Object (NEO). During close approaches, our current computational model is not able to provide a accurate data, due to the high speeds of these objects. We plan to refine our algorithms and improve accuracy in the future. To get precise data in these situations, it is recommended to use the JPL Horizons system.

Near Earth Object 2021 RO16 is in the constellation of Aries, at a distance of 105,813,063.0 kilometers from Earth. The current Right Ascension is 02h 55m 47s and the Declination is +16° 09’ 38” (apparent coordinates). The magnitude of Near Earth Object 2021 RO16 is 28.26.

Light Curve

The following chart shows the light curve of Near Earth Object 2021 RO16, 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.
