Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See 5 Cancri and Apparent magnitude
B-type main-sequence star
A B-type main-sequence star (B V) is a main-sequence (hydrogen-burning) star of spectral type B and luminosity class V. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K. B-type stars are extremely luminous and blue. 5 Cancri and b-type main-sequence star are b-type main-sequence stars.
See 5 Cancri and B-type main-sequence star
Be star
Be stars are a heterogeneous set of stars with B spectral types and emission lines. 5 Cancri and Be star are be stars.
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.
Cancer (constellation)
Cancer is one of the twelve constellations of the zodiac and is located in the Northern celestial hemisphere.
See 5 Cancri and Cancer (constellation)
Cancer in Chinese astronomy
According to traditional Chinese uranography, the modern constellation Cancer is located within the southern quadrant of the sky, which is symbolized as the Vermilion Bird of the South (南方朱雀, Nán Fāng Zhū Què). 5 Cancri and Cancer in Chinese astronomy are Cancer (constellation).
See 5 Cancri and Cancer in Chinese astronomy
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 5 Cancri 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 5 Cancri and Effective temperature
Light-year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.
List of stars in Cancer
This is the list of notable stars in the constellation Cancer. 5 Cancri and list of stars in Cancer are Cancer (constellation).
See 5 Cancri and List of stars in Cancer
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 5 Cancri and Monthly Notices of the Royal Astronomical Society
Photosphere
The photosphere is a star's outer shell from which light is radiated.
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 5 Cancri and Radial velocity
Solar luminosity
The solar luminosity is a unit of radiant flux (power emitted in the form of photons) conventionally used by astronomers to measure the luminosity of stars, galaxies and other celestial objects in terms of the output of the Sun.
See 5 Cancri and Solar luminosity
Solar mass
The solar mass is a standard unit of mass in astronomy, equal to approximately.
Solar radius
Solar radius is a unit of distance used to express the size of stars in astronomy relative to the Sun.
Spectral line
A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum.
See 5 Cancri and Spectral line
Star
A star is a luminous spheroid of plasma held together by self-gravity.
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
See 5 Cancri and Stellar classification
Stellar rotation
Stellar rotation is the angular motion of a star about its axis.
See 5 Cancri and Stellar rotation
Zodiac
The zodiac is a belt-shaped region of the sky that extends approximately 8° north and south (as measured in celestial latitude) of the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year.
