Absolute magnitude

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

See 3428 Roberts 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 3428 Roberts and Akari (satellite)

Albedo

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

See 3428 Roberts 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 3428 Roberts 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 3428 Roberts and Asteroid family

Asteroid spectral types

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

See 3428 Roberts 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 3428 Roberts and Astronomical unit

C-type asteroid

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

See 3428 Roberts and C-type asteroid

Coronagraph

A coronagraph is a telescopic attachment designed to block out the direct light from a star or other bright object so that nearby objects – which otherwise would be hidden in the object's bright glare – can be resolved.

See 3428 Roberts and Coronagraph

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 3428 Roberts and Degree (angle)

Ecliptic

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

See 3428 Roberts and Ecliptic

Ecliptic coordinate system

In astronomy, the ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations of Solar System objects.

See 3428 Roberts and Ecliptic coordinate system

The Goethe Link Observatory, observatory code 760, is an astronomical observatory near Brooklyn, Indiana, United States. 3428 Roberts and Goethe Link Observatory are Discoveries by Indiana University (Indiana Asteroid Program).

See 3428 Roberts and Goethe Link Observatory

Indiana Asteroid Program

The Indiana Asteroid Program was a photographic astronomical survey of asteroids during 1949–1967, at the U.S. Goethe Link Observatory near Brooklyn, Indiana. 3428 Roberts and Indiana Asteroid Program are Discoveries by Indiana University (Indiana Asteroid Program).

See 3428 Roberts and Indiana Asteroid Program

Indiana University Bloomington

Indiana University Bloomington (IU Bloomington, Indiana University, IU, or simply Indiana) is a public research university in Bloomington, Indiana.

See 3428 Roberts and Indiana University Bloomington

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 3428 Roberts 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 3428 Roberts 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 3428 Roberts 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 3428 Roberts 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 3428 Roberts and Light curve

List of observatory codes

This is a list of observatory codes (IAU codes or MPC codes) published by the Minor Planet Center.

See 3428 Roberts and List of observatory codes

Magnitude (astronomy)

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

See 3428 Roberts 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 3428 Roberts 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 3428 Roberts and Minor Planet Center

National Center for Atmospheric Research

The US National Center for Atmospheric Research (NCAR) is a US federally funded research and development center (FFRDC) managed by the nonprofit University Corporation for Atmospheric Research (UCAR) and funded by the National Science Foundation (NSF).

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 3428 Roberts 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 3428 Roberts and Orbital eccentricity

Orbital inclination

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

See 3428 Roberts and Orbital inclination

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 3428 Roberts and Photometry (astronomy)

Poles of astronomical bodies

The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere.

See 3428 Roberts and Poles of astronomical bodies

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 3428 Roberts 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 3428 Roberts 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 3428 Roberts and Rotation period (astronomy)

S-type asteroid

S-type asteroids are asteroids with a spectral type that is indicative of a siliceous (i.e. stony) mineralogical composition, hence the name.

See 3428 Roberts and S-type asteroid

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 3428 Roberts and Semi-major and semi-minor axes

Walter Orr Roberts

Walter Orr Roberts (August 20, 1915 – March 12, 1990) was an American astronomer and atmospheric physicist, as well as an educator, philanthropist, and builder.
