href="https://www.constellation-guide.com/constellation-list/cassiopeia-constellation/">Cassiopeia</a>. With an apparent magnitude of 3.37, it is the constellation’s fifth brightest star, after <a href="https://www.star-facts.com/gamma-cassiopeiae/">Gamma Cassiopeiae</a>, <a href="https://www.star-facts.com/schedar/">Schedar</a>, <a href="https://www.star-facts.com/caph/">Caph</a> and <a href="https://www.star-facts.com/ruchbah/">Ruchbah</a>. Segin lies at an approximate distance of 410 light years from Earth. It is the faintest of the five stars that form <a href="https://www.constellation-guide.com/cassiopeias-w/">Cassiopeia’s W</a>.</p><h2 style="text-align: center;">Star type</h2><p>Segin has the stellar classification B3 V, indicating a main sequence star still fusing hydrogen in its core, appearing blue or blue-white in colour. It is sometimes classified as a giant star of the spectral type B3 III.</p><p>Segin has a mass about 9.2 times that of the Sun and a radius 6 times solar. The radius is derived from the interferometrically measured angular diameter of 0.43 milliarcseconds.</p><p>With an effective temperature of 15,174 K, Segin shines with 2,500 solar luminosities. It has a projected rotational velocity of 30 km/s. Its estimated age is 15.4 million years.</p><div id="attachment_4317" style="width: 510px" class="wp-caption aligncenter"><img fetchpriority="high" decoding="async" aria-describedby="caption-attachment-4317" class="wp-image-4317" src="data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20500%20332'%3E%3C/svg%3E" alt="segin star,epsilon cassiopeiae" width="500" height="332" data-lazy-src="https://www.star-facts.com/wp-content/uploads/2020/08/Segin.webp" /><noscript><img fetchpriority="high" decoding="async" aria-describedby="caption-attachment-4317" class="wp-image-4317" src="https://www.star-facts.com/wp-content/uploads/2020/08/Segin.webp" alt="segin star,epsilon cassiopeiae" width="500" height="332" /></noscript><p id="caption-attachment-4317" class="wp-caption-text">Segin (Epsilon Cassiopeiae), image: Wikisky</p></div><p>A <a href="https://ui.adsabs.harvard.edu/abs/1993A%26A...274..870C/abstract">study</a> published in 1993 listed Segin as one of the known Be stars without an “e” or “shell” classification in the Bright Star Catalogue. Be stars are class B stars with lines of hydrogen in their spectra, indicating the presence of a circumstellar disk of gas ejected from the star.</p><p>Hipparcos measurements in the early 1990s suggested that Segin may be slightly variable. The star’s brightness varies with an amplitude of 0.0025 over a period of 2.15 hours.</p><p>Hipparcos observations also placed the star in the disputed Cassiopeia-Taurus (Cas-Tau) moving group, suggesting a likelihood of 93% that it is a member. The association may be physically related to the <a href="https://www.constellation-guide.com/alpha-persei-cluster/">Alpha Persei Cluster</a> as they share a similar velocity and distance.

The asterism appears as a W during the northern hemisphere spring and summer.

Even though it is the second most luminous of the W stars, Segin is the faintest because it is also the second most distant. Only <a href="https://www.star-facts.com/gamma-cassiopeiae/">Gamma Cassiopeiae</a> is more distant, lying about 550 light years away. <a href="https://www.star-facts.com/schedar/">Schedar</a>, <a href="https://www.star-facts.com/caph/">Caph</a>, and <a href="https://www.star-facts.com/ruchbah/">Ruchbah</a> are much closer to us, at 228, 54.7, and 99.4 light years respectively.</p><h2 style="text-align: center;">Name</h2><p>The origin of the name Segin (pronunciation: /ˈsɛɡɪn/) is uncertain. It may be a mistranscription of Seginus, another name with an uncertain origin, which now formally applies to <a href="https://www.star-facts.com/seginus/">Gamma Boötis</a>.</p><p>The name was officially approved by the International Astronomical Union’s (IAU) Working Group on Star Names (WGSN) on September 5, 2017.</p><p>Epsilon Cassiopeiae once shared the name Ruchbah with <a href="https://www.star-facts.com/ruchbah/">Delta Cassiopeiae</a>, which has kept the name.</p><p>In Chinese astronomy, Segin is known as 閣道二 (<em>Gé Dào èr</em>), the Second Star of Flying Corridor.
