MIRA VARIABLE STAR
A Mira variable star is a variable star whose brightness and size cycle over a very long time period, in the order of many months.
[2480] omicron Ceti or Mira was the first variable star to be found in the night sky. It is a red giant approximately 420 light-years distant from Earth. Its maximum magnitude can reach 2.
Mira (Omicron Ceti) is a well-known variable in the called . It was discovered in 1596 by David Fabricus, an amateur Dutch . Mira (meaning "wonderful") was named by Johannes Hevelius in 1662.
Mira (Omicron Ceti) is a well-known variable red giant star in the constellation called Cetus. It was discovered in 1596 by David Fabricus, an amateur Dutch astronomer. Mira (meaning "wonderful") was named by Johannes Hevelius in 1662.
In 1572, and again in 1604, supernovae appeared in the sky, and in 1596 David Fabricius discovered that the star Omicron Ceti disappeared periodically. This star was then named Mira ("Miraculous Star").
13 is Mira (Omicron Ceti), whose surface temperature (3000 K), is about half that of the Sun and whose luminosity is some 400 times greater than the Sun's.
Among the most dramatic and fascinating stars of the sky are the "long-period variables," the "LPVs," epitomized by the first one found, Mira (Omicron Ceti, in 1596), so much so that these ultra-variables are also called "Miras.
Its common name is omicron Ceti. Its discovery is credited to in 1596. Mira typically ranges from 9.3 to 3.4 over a 333 day period, but William Herschel observed it brighter than magnitude 1.0.
79 Ceti is located around 117 light-years from Sol, in the northeastern corner (2:35:19.9-3:33:38.2, ICRS 2000.0) of Constellation Cetus, the Whale or Sea Monster -- east of Mira (Omicron Ceti), south of Delta Ceti, ...
