Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See 7 Arietis and Apparent magnitude
Aries (constellation)
Aries is one of the constellations of the zodiac.
See 7 Arietis and Aries (constellation)
Binary star
A binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other.
Bortle scale
The Bortle dark-sky scale (usually referred to as simply the Bortle scale) is a nine-level numeric scale that measures the night sky's brightness of a particular location.
See 7 Arietis and Bortle scale
British Astronomical Association
The British Astronomical Association (BAA) was formed in 1890 as a national body to support the UK's amateur astronomers.
See 7 Arietis and British Astronomical Association
Constellation
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object.
See 7 Arietis and Constellation
Effective temperature
The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation.
See 7 Arietis and Effective temperature
Flamsteed designation
A Flamsteed designation is a combination of a number and constellation name that uniquely identifies most naked eye stars in the modern constellations visible from southern England.
See 7 Arietis and Flamsteed designation
Giant star
A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature.
Margin of error
The margin of error is a statistic expressing the amount of random sampling error in the results of a survey.
See 7 Arietis and Margin of error
Minute and second of arc
A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol, is a unit of angular measurement equal to of one degree.
See 7 Arietis and Minute and second of arc
Monthly Notices of the Royal Astronomical Society
Monthly Notices of the Royal Astronomical Society (MNRAS) is a peer-reviewed scientific journal in astronomy, astrophysics and related fields.
See 7 Arietis and Monthly Notices of the Royal Astronomical Society
Parallax
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight and is measured by the angle or half-angle of inclination between those two lines.
Radial velocity
The radial velocity or line-of-sight velocity of a target with respect to an observer is the rate of change of the vector displacement between the two points.
See 7 Arietis and Radial velocity
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
See 7 Arietis and Stellar classification
Stellar evolution
Stellar evolution is the process by which a star changes over the course of its lifetime and how it can lead to the creation of a new star.
See 7 Arietis and Stellar evolution
Sun
The Sun is the star at the center of the Solar System.
Variable-star designation
In astronomy, a variable-star designation is a unique identifier given to variable stars. 7 Arietis and variable-star designation are objects with variable star designations.
See 7 Arietis and Variable-star designation
