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 2090 Mizuho and Akari (satellite)

Albedo

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

See 2090 Mizuho 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 2090 Mizuho 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 2090 Mizuho and Asteroid belt

Asteroid spectral types

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

See 2090 Mizuho 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 2090 Mizuho and Astronomical unit

C-type asteroid

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

See 2090 Mizuho 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 2090 Mizuho and Degree (angle)

Ecliptic

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

See 2090 Mizuho 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.

See 2090 Mizuho and Heidelberg-Königstuhl State Observatory

Hour

An hour (symbol: h; also abbreviated hr) is a unit of time historically reckoned as of a day and defined contemporarily as exactly 3,600 seconds (SI).

See 2090 Mizuho and Hour

JCPM Yakiimo Station

The JCPM Yakiimo Station is an astronomical observatory station at Shimizu, Shizuoka prefecture, Japan.

See 2090 Mizuho and JCPM Yakiimo Station

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 2090 Mizuho 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 2090 Mizuho 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 2090 Mizuho 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 2090 Mizuho 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 2090 Mizuho and Light curve

Magnitude (astronomy)

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

See 2090 Mizuho 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 2090 Mizuho 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 2090 Mizuho 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 2090 Mizuho 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 2090 Mizuho and Orbital eccentricity

Orbital inclination

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

See 2090 Mizuho and Orbital inclination

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 2090 Mizuho 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 2090 Mizuho and S-type asteroid

Simeiz Observatory

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

See 2090 Mizuho and Simeiz Observatory

Springer Science+Business Media, commonly known as Springer, is a German multinational publishing company of books, e-books and peer-reviewed journals in science, humanities, technical and medical (STM) publishing.
