Astronomical objects discovered in 1932

Albedo

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

See 1218 Aster and Albedo

Aster (genus)

Aster is a genus of perennial flowering plants in the family Asteraceae.

See 1218 Aster and Aster (genus)

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 1218 Aster 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 1218 Aster and Asteroid belt

Astronomical unit

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

See 1218 Aster and Astronomical unit

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 1218 Aster and Degree (angle)

Ecliptic

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

See 1218 Aster and Ecliptic

Heidelberg-Königstuhl State Observatory

Heidelberg-Königstuhl State Observatory (Landessternwarte Heidelberg-Königstuhl) is a historic astronomical observatory located near the summit of the Königstuhl hill in the city of Heidelberg in Germany.

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 1218 Aster 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 1218 Aster 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 1218 Aster and Julian year (astronomy)

Karl Wilhelm Reinmuth

Karl Wilhelm Reinmuth (4 April 1892 in Heidelberg – 6 May 1979 in Heidelberg) was a German astronomer and a prolific discoverer of 395 minor planets. 1218 Aster and Karl Wilhelm Reinmuth are Discoveries by Karl Wilhelm Reinmuth.

See 1218 Aster and Karl Wilhelm Reinmuth

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 1218 Aster and Kirkwood gap

Light curve

In astronomy, a light curve is a graph of the light intensity of a celestial object or region as a function of time, typically with the magnitude of light received on the y-axis and with time on the x-axis.

See 1218 Aster and Light curve

List of minor planet discoverers

This is a list of minor-planet discoverers credited by the Minor Planet Center with the discovery of one or several minor planets (such as near-Earth and main-belt asteroids, Jupiter trojans and distant objects).

See 1218 Aster and List of minor planet discoverers

Magnitude (astronomy)

In astronomy, magnitude is measure of the brightness of an object, usually in a defined passband.

See 1218 Aster and Magnitude (astronomy)

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 1218 Aster and Minor planet

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 1218 Aster and Observation arc

Observatory of Turin

The Observatory of Turin (Osservatorio Astronomico di Torino, also known as Pino Torinese; obs. code: 022) is an astronomical observatory owned and operated by Italy's National Institute for Astrophysics (Istituto Nazionale di Astrofisica, INAF).

See 1218 Aster and Observatory of Turin

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 1218 Aster and Orbital eccentricity

Orbital inclination

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

See 1218 Aster and Orbital inclination

Paul Herget

Paul Herget (January 30, 1908 – August 27, 1981) was an American astronomer and director of the Cincinnati Observatory, who established the Minor Planet Center after World War II.

See 1218 Aster and Paul Herget

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 1218 Aster and Rotation period (astronomy)
