Albedo

Albedo is the fraction of sunlight that is diffusely reflected by a body.

See 1851 Lacroute and Albedo

Asteroid

An asteroid is a minor planet—an object that is neither a true planet nor an identified comet— that orbits within the inner Solar System.

See 1851 Lacroute and Asteroid

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.

See 1851 Lacroute and Asteroid belt

Astrometry

Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies.

See 1851 Lacroute and Astrometry

Astronomical unit

The astronomical unit (symbol: au, or AU) is a unit of length defined to be exactly equal to.

See 1851 Lacroute and Astronomical unit

Astronomische Gesellschaft Katalog

The Astronomische Gesellschaft Katalog (AGK) is an astrometric star catalogue of the Northern hemisphere.

See 1851 Lacroute and Astronomische Gesellschaft Katalog

Center of Research in Astronomy, Astrophysics, and Geophysics

The Algiers Observatory was built in the late 19th century in the Algiers suburb of Bouzaréah, Algeria, North Africa.

See 1851 Lacroute and Center of Research in Astronomy, Astrophysics, and Geophysics

Degree (angle)

A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees.

See 1851 Lacroute and Degree (angle)

Ecliptic

The ecliptic or ecliptic plane is the orbital plane of Earth around the Sun.

See 1851 Lacroute and Ecliptic

International Astronomical Union

The International Astronomical Union (IAU; Union astronomique internationale, UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation.

See 1851 Lacroute and International Astronomical Union

IRAS

The Infrared Astronomical Satellite (Dutch: Infrarood Astronomische Satelliet) (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths.

See 1851 Lacroute and IRAS

Jet Propulsion Laboratory

Jet Propulsion Laboratory (JPL) is a Federally Funded Research and Development Center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States.

See 1851 Lacroute and Jet Propulsion Laboratory

Julian day

The Julian day is the continuous count of days since the beginning of the Julian period, and is used primarily by astronomers, and in software for easily calculating elapsed days between two events (e.g. food production date and sell by date).

See 1851 Lacroute and Julian day

Julian year (astronomy)

In astronomy, a Julian year (symbol: a or aj) is a unit of measurement of time defined as exactly 365.25 days of SI seconds each.

See 1851 Lacroute and Julian year (astronomy)

Kirkwood gap

A Kirkwood gap is a gap or dip in the distribution of the semi-major axes (or equivalently of the orbital periods) of the orbits of main-belt asteroids.

See 1851 Lacroute and Kirkwood gap

Louis Boyer (astronomer)

Louis Boyer (1901–1999) was a French astronomer who worked at the Algiers Observatory, North Africa, where he discovered 40 asteroids between 1930 and 1952. 1851 Lacroute and Louis Boyer (astronomer) are Discoveries by Louis Boyer (astronomer).

See 1851 Lacroute and Louis Boyer (astronomer)

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.

See 1851 Lacroute and Minor planet

Minor Planet Center

The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU).

See 1851 Lacroute and Minor Planet Center

Observation arc

In observational astronomy, the observation arc (or arc length) of a Solar System body is the time period between its earliest and latest observations, used for tracing the body's path.

See 1851 Lacroute and Observation arc

Observatory of Strasbourg

The Observatory of Strasbourg is an astronomical observatory in Strasbourg, France.

See 1851 Lacroute and Observatory of Strasbourg

Orbital eccentricity

In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle.

See 1851 Lacroute and Orbital eccentricity

Orbital inclination

Orbital inclination measures the tilt of an object's orbit around a celestial body.

See 1851 Lacroute and Orbital inclination

Photographic plate

Photographic plates preceded photographic film as a capture medium in photography.

See 1851 Lacroute and Photographic plate

Pierre Lacroute

Pierre Lacroute (1906–1993), was a French astrophysicist and pioneer of astrometry using satellite experiments.

See 1851 Lacroute and Pierre Lacroute

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.

See 1851 Lacroute and Precovery

Rotation period (astronomy)

In astronomy, the rotation period or spin period of a celestial object (e.g., star, planet, moon, asteroid) has two definitions.

See 1851 Lacroute and Rotation period (astronomy)
