Absolute magnitude

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

See 2324 Janice 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 2324 Janice and Akari (satellite)

Albedo

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

See 2324 Janice 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 2324 Janice 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 2324 Janice 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 2324 Janice and Asteroid family

Asteroid spectral types

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

See 2324 Janice and Asteroid spectral types

Astrometry

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

See 2324 Janice and Astrometry

Astronomical unit

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

See 2324 Janice and Astronomical unit

C-type asteroid

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

See 2324 Janice and C-type asteroid

California Institute of Technology

The California Institute of Technology (branded as Caltech) is a private research university in Pasadena, California.

See 2324 Janice and California Institute of Technology

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 2324 Janice and Degree (angle)

Ecliptic

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

See 2324 Janice and Ecliptic

Eleanor F. Helin

Eleanor Francis "Glo" Helin (née Francis, 19 November 1932 – 25 January 2009) was an American astronomer. 2324 Janice and Eleanor F. Helin are Discoveries by Eleanor F. Helin.

See 2324 Janice and Eleanor F. Helin

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 2324 Janice and Jet Propulsion Laboratory

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 2324 Janice 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 2324 Janice 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 2324 Janice 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 2324 Janice and Light curve

Lowell Observatory

Lowell Observatory is an astronomical observatory in Flagstaff, Arizona, United States.

See 2324 Janice and Lowell Observatory

Magnitude (astronomy)

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

See 2324 Janice 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 2324 Janice 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 2324 Janice 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 2324 Janice 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 2324 Janice and Orbital eccentricity

Orbital elements

Orbital elements are the parameters required to uniquely identify a specific orbit.

See 2324 Janice and Orbital elements

Orbital inclination

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

See 2324 Janice and Orbital inclination

Palomar Observatory

Palomar Observatory is an astronomical research observatory in the Palomar Mountains of San Diego County, California, United States.

See 2324 Janice and Palomar Observatory

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 2324 Janice and Proper orbital elements

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 2324 Janice and Rotation period (astronomy)

Schelte J. Bus

Schelte John "Bobby" Bus (born 1956) is an American astronomer and discoverer of minor planets at the Institute for Astronomy of the University of Hawaiʻi and deputy director of NASA's Infrared Telescope Facility (IRTF) at the Mauna Kea Observatory in Hawaii, United States.
