*[astronomy]* Magnitude is the logarithmic measure of the brightness of an object, in astronomy, measured in a specific wavelength or passband, usually in optical or near-infrared wavelengths. The sun has an apparent magnitude of −27, a full moon −13 and the brightest planet Venus measures −5. The brightest man-made objects, Iridium fla...

*[mathematics]* In mathematics, magnitude is the size of a mathematical object, a property by which the object can be compared as larger or smaller than other objects of the same kind. More formally, an object`s magnitude is an ordering (or ranking) of the class of objects to which it belongs. ==History== The Greeks distinguished between seve...

A measure of the strength of an earthquake based on the amount of movement recorded by a seismograph . compare Richter scale.

Found on https://www.encyclo.co.uk/local/22327

A measure of the strength of an earthquake. There are several scales depending on which part of the seismogram is examined. These include Richter local magnitude (ML), Body wave magnitude (mb) and surface wave magnitude (Ms). Moment magnitude (Mw) is calculated from spectral analysis.

A way of expressing the brightness of astronomical objects inherited from the Greeks. In the magnitude system, a lower number indicates a brighter object (for example, a 1st magnitude star is brighter than a 3rd magnitude star). Each step in magnitude corresponds to a brightnesss difference of a factor of about 2.5. Stars of the 6th magnitude are t...
