1414 Jérôme, provisional designation , is a carbonaceous Dorian
asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.

from the central region of the
asteroid belt, approximately 16 kilometers in diameter. It was discovered on 12 February 1937 by, French astronomer
Louis Boyer at
Algiers Observatory, Algeria, in northern Africa, and named after his father Jérôme Boyer.
Orbit and classification
''Jérôme'' is a member of the
Dora family (), a well-established central
asteroid family
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An a ...

The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodi ...
. It is alternatively known as the "Zhongolovich family", named after its presumably largest member
1734 Zhongolovich. The Dora family may also contain a subfamily.
''Jérôme'' orbits the Sun in the
middle main-belt at a distance of 2.3–3.2
AU once every 4 years and 8 months (1,697 days). Its orbit has an
eccentricity of 0.16 and an
inclination of 9
° with respect to the
ecliptic.
The body's
observation arc starts with its official discovery observation, as no
precoveries were taken and no prior identifications were made.
Physical characteristics
''Jérôme'' is a dark
C-type asteroid, classified as a hydrated Ch-subtype in the
SMASS classification scheme.
According to the surveys carried out by the Infrared Astronomical Satellite
IRAS and NASA's
Wide-field Infrared Survey Explorer with its subsequent
NEOWISE mission, ''Jérôme'' measures 15.1 and 17.2 kilometers in diameter, and its surface has an
albedo of 0.065 and 0.054, respectively.
It has an absolute
magnitude of 13.1.

Naming
This
minor planet was named by the discoverer in honour of his father, Jérôme Boyer.
Naming citation was first mentioned in ''
The Names of the Minor Planets'' by
Paul Herget in 1955 ().
