Difference between Apparent magnitude and Stellar classification

Apparent magnitude vs. Stellar classification

The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth. In astronomy, stellar classification is the classification of stars based on their spectral characteristics.

Similarities between Apparent magnitude and Stellar classification

Apparent magnitude and Stellar classification have 22 things in common (in Unionpedia): Alpha Centauri, Arcturus, Betelgeuse, European Southern Observatory, Infrared, Jupiter, Luminosity, Magnitude (astronomy), Milky Way, Photometric system, Red dwarf, Rigel, Sirius, Star, Stellar classification, Sun, Supergiant star, The Astrophysical Journal, UBV photometric system, Ultraviolet, Vega, Visible spectrum.

Alpha Centauri

Alpha Centauri (α Centauri, abbreviated Alf Cen or α Cen) is the star system closest to the Solar System, being from the Sun.

Betelgeuse

Betelgeuse, also designated Alpha Orionis (α Orionis, abbreviated Alpha Ori, α Ori), is the ninth-brightest star in the night sky and second-brightest in the constellation of Orion.

European Southern Observatory

The European Southern Observatory (ESO) is a 15-nation intergovernmental research organization for ground-based astronomy.

Infrared

Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.

Luminosity

In astronomy, luminosity is the total amount of energy emitted per unit of time by a star, galaxy, or other astronomical object.

Magnitude (astronomy)

In astronomy, magnitude is a logarithmic measure of the brightness of an object in a defined passband, often in the visible or infrared spectrum, but sometimes across all wavelengths.

Milky Way

The Milky Way is the galaxy that contains our Solar System.

Photometric system

In astronomy, a photometric system is a set of well-defined passbands (or filters), with a known sensitivity to incident radiation.

Red dwarf

A red dwarf (or M dwarf) is a small and relatively cool star on the main sequence, of M spectral type.

Rigel

Rigel, also designated Beta Orionis (β Orionis, abbreviated Beta Ori, β Ori), is generally the seventh-brightest star in the night sky and the brightest star in the constellation of Orion—though periodically it is outshone within the constellation by the variable Betelgeuse.

Sirius

Sirius (a romanization of Greek Σείριος, Seirios,."glowing" or "scorching") is a star system and the brightest star in the Earth's night sky.

The Astrophysical Journal

The Astrophysical Journal, often abbreviated ApJ (pronounced "ap jay") in references and speech, is a peer-reviewed scientific journal of astrophysics and astronomy, established in 1895 by American astronomers George Ellery Hale and James Edward Keeler.

UBV photometric system

The UBV photometric system (Ultraviolet, Blue, Visual), also called the Johnson system (or Johnson-Morgan system), is a wide band photometric system for classifying stars according to their colors.

Ultraviolet

Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.

Vega

Vega, also designated Alpha Lyrae (α Lyrae, abbreviated Alpha Lyr or α Lyr), is the brightest star in the constellation of Lyra, the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus.
