Absolute magnitude

In astronomy, absolute magnitude is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale.

See 930 Westphalia and Absolute magnitude

Akari (satellite)

AKARI (ASTRO-F) was an infrared astronomy satellite developed by Japan Aerospace Exploration Agency, in cooperation with institutes of Europe and Korea.

See 930 Westphalia and Akari (satellite)

Albedo

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

See 930 Westphalia and Albedo

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 930 Westphalia and Asteroid belt

Asteroid family

An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination.

See 930 Westphalia and Asteroid family

Asteroid spectral types

An asteroid spectral type is assigned to asteroids based on their reflectance spectrum, color, and sometimes albedo.

See 930 Westphalia and Asteroid spectral types

Astronomical unit

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

See 930 Westphalia and Astronomical unit

C-type asteroid

C-type (carbonaceous) asteroids are the most common variety, forming around 75% of known asteroids.

See 930 Westphalia and C-type asteroid

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 930 Westphalia and Degree (angle)

Ecliptic

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

See 930 Westphalia and Ecliptic

Hamburg Observatory

Hamburg Observatory (Hamburger Sternwarte) is an astronomical observatory located in the Bergedorf borough of the city of Hamburg in northern Germany.

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.

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.

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 930 Westphalia 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 930 Westphalia 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 930 Westphalia 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 930 Westphalia and Light curve

List of slow rotators (minor planets)

This is a list of slow rotators—minor planets that have an exceptionally long rotation period. 930 Westphalia and list of slow rotators (minor planets) are slow rotating minor planets.

Magnitude (astronomy)

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

See 930 Westphalia 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 930 Westphalia 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 930 Westphalia and Observation arc

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 930 Westphalia and Orbital eccentricity

Orbital inclination

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

See 930 Westphalia 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 930 Westphalia and Paul Herget

Photometry (astronomy)

In astronomy, photometry, from Greek photo- ("light") and -metry ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects.

See 930 Westphalia and Photometry (astronomy)

Proper orbital elements

The proper orbital elements or proper elements of an orbit are constants of motion of an object in space that remain practically unchanged over an astronomically long timescale.

See 930 Westphalia and Proper orbital elements

Provisional designation in astronomy

Provisional designation in astronomy is the naming convention applied to astronomical objects immediately following their discovery.

See 930 Westphalia and Provisional designation in astronomy

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 930 Westphalia and Rotation period (astronomy)

Semi-major and semi-minor axes

In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the two most widely separated points of the perimeter.

See 930 Westphalia and Semi-major and semi-minor axes

Simeiz Observatory

Simeiz Observatory (also spelled Simeis or Simeïs) was an astronomy research observatory until the mid-1950s.
