asteroid
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids). As ...

asteroid belt
The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids ...
, approximately 9 kilometers in diameter. It was discovered on 23 April 1930, by Dutch astronomer
Hendrik van Gent at the
Leiden Southern Station, annex to the
Johannesburg Observatory in South Africa.
Orbit and characterization
''Ariane'' orbits the Sun at a distance of 2.1–2.4
AU once every 3 years and 4 months (1,219 days). Its orbit has an
eccentricity
Eccentricity or eccentric may refer to:
* Eccentricity (behavior), odd behavior on the part of a person, as opposed to being "normal"
Mathematics, science and technology Mathematics
* Off-Centre (geometry), center, in geometry
* Eccentricity (g ...

inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object.

° with respect to the
ecliptic
The ecliptic or ecliptic plane is the orbital plane of Earth's orbit, Earth around the Sun. It was a central concept in a number of ancient sciences, providing the framework for key measurements in astronomy, astrology and calendar-making.

rotation period
In astronomy, the rotation period or spin period of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the '' sidereal rotation period'' (or ''sidereal day''), i.e., the time that the objec ...

Naming
This
minor planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor ...

Gabriel Marcel
Gabriel Honoré Marcel (7 December 1889 – 8 October 1973) was a French philosopher, playwright, music critic and leading Christian existentialist. The author of over a dozen books and at least thirty plays, Marcel's work focused on the moder ...
(1889–1973).
The official naming citation was first mentioned in ''
The Names of the Minor Planets'' by
Paul Herget in 1955 ().
