1767 Lampland, provisional designation , is an Eoan
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 outer regions of the
asteroid belt, approximately 15 kilometers in diameter. It was discovered on 7 September 1962, by astronomers of the
Indiana Asteroid Program at
Goethe Link Observatory
The Goethe Link Observatory, observatory code 760, is an astronomical observatory near Brooklyn, Indiana, United States. It is owned by Indiana University and operated by the Indiana Astronomical Society https://iasindy.org/about.html, which effo ...

Orbit and classification
''Lampland'' a member the
Eos family The Eos family (''adj. Eoan'' ; ) is a very large asteroid family located in the outer region of the asteroid belt. The family of K-type asteroids is believed to have formed as a result of an ancient catastrophic collision. The family's parent body ...
(), the largest
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 ...
in the
outer main belt consisting of nearly 10,000 asteroids.
It orbits the Sun at a distance of 2.7–3.3
AU once every 5 years and 3 months (1,915 days). Its orbit has an
eccentricity of 0.10 and an
inclination of 10
° with respect to the
ecliptic.
The asteroid was first identified as at
Uccle Observatory in September 1941. The body's
observation arc begins with a
precovery
In astronomy, precovery (short for pre-discovery recovery) is the process of finding the image of an object in images or photographic plates predating its discovery, typically for the purpose of calculating a more accurate orbit. This happens mos ...

Physical characteristics
In the
Tholen classification, its
spectral type is ambiguous, closest to the
X-type asteroid and with some resemblance to the
C-type asteroids
C-type (carbonaceous) asteroids are the most common variety, forming around 75% of known asteroids. They are volatile-rich and distinguished by a very low albedo because their composition includes a large amount of carbon, in addition to rock ...

while the overall spectral type of the Eos family is that of a
K-type.
Rotation period
As of 2017, no rotational
lightcurve of ''Lampland'' has been obtained from photometric observations. The asteroid's
rotation period
The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) may refer to its sidereal rotation period, i.e. the time that the object takes to complete a single revolution around its axis of rotation relative to the ...

Diameter and albedo
According to the survey carried out by the
NEOWISE mission of NASA's
Wide-field Infrared Survey Explorer, ''Lampland'' measures 15.448 kilometers in diameter and its surface has an
albedo of 0.116.
Naming
This
minor planet was named after American astronomer
Carl Lampland (1873–1951), a graduate of
Indiana University, best known for his radiometric measurements of planetary temperatures.
Lampland is also honored by
a lunar and by
a Martian crater. The name was proposed by
Frank K. Edmondson
Frank Kelley Edmondson (August 1, 1912 – December 8, 2008) was an American astronomer.
