| '''3671 Dionysus''' is a small binary [[Amor asteroid]], orbiting between the [[Earth]] and the [[asteroid belt]]. It was discovered by [[Carolyn Shoemaker|Carolyn]] and [[Gene Shoemaker]] at [[Palomar Observatory]] on 27 May 1984. It is named after [[Dionysus]], the [[Greek god]] of wine. Its [[provisional designation]] was '''1984 KD'''. It is an [[List of Earth-crossing minor planets|outer Earth grazer]] because its perihelion is just within Earth's orbit.
| |
| | |
| == Near-Earth object ==
| |
| Dionysus makes many close approaches to Earth. Its closest approach so far occurred in 1984, when Dionysus passed just {{convert|0.03047|AU|km}} from Earth.<ref name=jpldata/> Dionysus is expected to continue to make close approaches.
| |
| | |
| == Moon ==
| |
| In 1997, a team of astronomers at the [[European Southern Observatory]] announced that [[lightcurve]] observations indicate the presence of a small moon orbiting Dionysus. Its provisional designation is S/1997 (3671) 1. This moon measures 300 meters in diameter, and orbits 3.6km from Dionysus with an [[Orbital eccentricity|eccentricity]] of 0.07 and an [[orbital period]] of 27.72 hours.<ref name=johnston>[http://www.johnstonsarchive.net/astro/astmoons/am-03671.html Johnston's Archive: (3671) Dionysus and S/1997 (3671) 1]</ref> From the surface of Dionysus, S/1997 (3671) 1 would have an apparent diameter of roughly 3.02 degrees.<ref group="lower-alpha">Calculated by solving the equation <math> \scriptstyle{\mathrm{tan}\left(\frac{\theta}{2}\right) = \frac{\mathrm{radius~of~moon}}{\mathrm{distance~from~surface~of~asteroid~to~center~of~moon}}}</math>.</ref> For comparison, the [[Sun]] appears to be 0.5° from Earth.
