Target Asteroid 3671 Dionysus
Target asteroid 3671 Dionysus is a small binary Amor asteroid, orbiting between Earth and the asteroid belt, It is an outer Earth grazer because its perihelion is just within Earth's orbit. (MOID) is less than 0.05 AU and its diameter is greater than 150 meters. The Earth-MOID is 0.01989 AU (2,976,000 km; 1,849,000 mi).[ Its orbit is well-determined for the next several hundred years.
Dionysus makes modestly close approaches to Earth. On 19 June 1984 Dionysus passed 0.0305 AU (4,560,000 km; 2,840,000 mi) from Earth. On 18 June 2085 it will pass 0.028 AU (4,200,000 km; 2,600,000 mi) from Earth. 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. Confirmation of the satellite. Contacts were made with observers located at other observatories, in order to secure lightcurve coverage over a longer period of time than was possible from La Silla.
Amor asteroids -- whose orbits approach but do not cross Earth orbit, and whose orbits are further from the Sun than Earth's orbit. Many have orbits that reside entirely between Earth and Mars. Some of these are economically attractive in the near term. Asteroids are small solid planetary bodies revolving around the Sun in orbits that are mostly located in the so-called Main Asteroid Belt, confined between the orbits of Mars and Jupiter. Most of them are thought to be fragments.
What is the asteroid belt?
The asteroid belt is a region of our solar system – between the orbits of Mars and Jupiter – in which many small bodies orbit our sun.
Dionysus was the ancient Greek god of wine, winemaking, grape cultivation, fertility, ritual madness, theater, and religious ecstasy. He is known as the patron of arts and is the son of Zeus and Semele, although in some versions he is the son of Hades (or Zeus) and Persephone, who also in some versions is his sister. He is also known as Bacchus (Greek: Βάκχος, Bákkhos), the name adopted by the Romans. The cult of Dionysos became significant in Athens from the 6th century BCE and the Dionysia festival of Athens and other cities. The essays offer coverage of Dionysus in Roman art, Italian epigraphy; Latin poetry including epic, drama, and elegy; and prose, including historiography, rhetorical and Christian discourse.
The introduction offers an overview of the presence of Dionysus in Italy from the archaic to the imperial periods, identifying the main scholarly trends, with the treatment of key Dionysian episodes in Roman history and literature.
