Apparent magnitude

Apparent magnitude is a measure of the brightness of a star or other astronomical object.

See 721 Tabora and Apparent magnitude

Asteroid spectral types

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

See 721 Tabora and Asteroid spectral types

Cargo liner

A cargo liner, also known as a passenger-cargo ship or passenger-cargoman, is a type of merchant ship which carries general cargo and often passengers.

See 721 Tabora and Cargo liner

Cybele asteroids

The Cybele asteroids (also known as the "Cybeles") are a dynamical group of asteroids, named after the asteroid 65 Cybele.

See 721 Tabora and Cybele asteroids

D-type asteroid

D-type asteroids have a very low albedo and a featureless reddish spectrum.

See 721 Tabora and D-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 721 Tabora and Degree (angle)

Deutsche Ost-Afrika Linie

Deutsche Ost-Afrika Linie (German East Africa Line, or DOAL) was a shipping line, established in 1890 as an alternative to the existing shipping services to East Africa, including German East Africa (1891–1919), then dominated by United Kingdom shipping lines.

See 721 Tabora and Deutsche Ost-Afrika Linie

Ecliptic

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

See 721 Tabora and Ecliptic

Franz Kaiser

Franz Heinrich Kaiser (25 April 1891 – 13 March 1962) was a German astronomer. 721 Tabora and Franz Kaiser are Discoveries by Franz Kaiser.

Hamburg

Hamburg (Hamborg), officially the Free and Hanseatic City of Hamburg,.

See 721 Tabora and Hamburg

Heidelberg

Heidelberg (Heidlberg) is a city in the German state of Baden-Württemberg, situated on the river Neckar in south-west Germany.

See 721 Tabora and Heidelberg

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 721 Tabora and Jet Propulsion Laboratory

JPL Small-Body Database

The JPL Small-Body Database (SBDB) is an astronomy database about small Solar System bodies.

See 721 Tabora and JPL Small-Body Database

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 721 Tabora and Julian day

Jupiter

Jupiter is the fifth planet from the Sun and the largest in the Solar System.

See 721 Tabora and Jupiter

Kilometre

The kilometre (SI symbol: km; or), spelt kilometer in American English and Philippine English, is a unit of length in the International System of Units (SI), equal to one thousand metres (kilo- being the SI prefix for). It is the preferred measurement unit to express distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is used.

See 721 Tabora and Kilometre

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 721 Tabora and Light curve

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 721 Tabora and Minor planet

NASA

The National Aeronautics and Space Administration (NASA) is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research.

See 721 Tabora and NASA

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 721 Tabora and Orbital eccentricity

Orbital period

The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object.

See 721 Tabora and Orbital period

Orbital plane

The orbital plane of a revolving body is the geometric plane in which its orbit lies.

See 721 Tabora and Orbital plane

Orbital resonance

In celestial mechanics, orbital resonance occurs when orbiting bodies exert regular, periodic gravitational influence on each other, usually because their orbital periods are related by a ratio of small integers.

See 721 Tabora and Orbital resonance

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 721 Tabora and Photometry (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 721 Tabora and Rotation period (astronomy)

Sun

The Sun is the star at the center of the Solar System.
