# 2023 R3

2023 R3 is a hyperbolic [asteroid](https://spacecatalog.org/asteroids). Its orbit does not close: it passes within 1.35826 AU of the [Sun](https://spacecatalog.org/object/sun) once and never returns. Its absolute magnitude (H) is 19.96. Other catalogues list it as (A/2023 R3).

## At a glance

- **WHAT IT IS:** Hyperbolic asteroid
- **HOW BRIGHT IN ITSELF (H):** 19.96 — How bright it would look from a fixed, standard distance — a measure of the object rather than of the view from here.

## Properties

| Quantity | Value |
| --- | --- |
| CLASS | Hyperbolic asteroid |
| ORBITS | Sun |
| PERIHELION | 1.35826 AU ±0.00067 |

## Catalogue data

### THE ORBIT

The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.

| Field | Value |
| --- | --- |
| Eccentricity | 1.00009 ±0.0014 |
| Hyperbolic excess velocity | 0.24 ±2 km/s |
| Inclination | 12.11 ±0.015° |
| Longitude of ascending node | 347.39 ±0.026° |
| Argument of perihelion | 86.85 ±0.044° |
| Mean anomaly | 0° |
| Element epoch | 2460210.5000 JD |
| Perihelion passage | 2460296.6879 JD |
| Minimum distance from Earth's orbit | 0.445614 AU |
| Orbit class | HYA |
