The primary of VV Cephei may well be the largest known red supergiant star, so extended that with the Sun at its center the orbit of Mars would easily be contained inside it. 23) Which of the following makes the planet Saturn unique in the solar family? For the past 190 years or The star has mystified astronomers for nearly two centuries despite the fact that its easily visible to the The only stars in the northern celestial hemisphere brighter than Capella are Arcturus in Botes constellation and Vega in Lyra.The only other star visible from northern latitudes that is brighter than Capella is Sirius in the southern constellation At the time this hypothesis was impossible to confirm, since the space era had not yet begun 2 (p. 179, my translation). These occur periodically at a distance of approximately nine years and can last up to 100 days. Hack developed the hypothesis that Epsilon Aurigae is a Be-star-like hot object at the centre of a large disk of occulting material 1 (p. 549). For the year 2014, it is expected again. The unusual behavior of Epsilon Aurigae makes its binary-star status questionable.The Epsilon Aurigae is particularly known However, in Algol binaries such as Epsilon Aurigae, the lower-mass star evolves faster as it gobbles up material from its companion. That's probably what happened to the strange dimming star, Stencel said. Over 20 million years, the more massive star dumped its material, most of which ended up on the companion.

The star's spectral features indicate that it is a F-class supergiant star with 20 times the mass and 300 times as wide as our Sun, and two competing theories suggest either that Epsilon Aurigae is a massive supergiant, periodically eclipsed by two tight-knit stars inside a swirling, dusty disc, or that it is in fact a dying star with a lot less mass, periodically eclipsed by just a Auriga, Charioteer - a conspicuous constellation in the northern hemisphere; between Great Bear and Orion at edge of Milky Way. Repeat for as many check stars you want to use. The images of the star and wedge-shaped structure show the direct motion over a month, yielding a measurement of the relative masses of the components. "Close up" in this case is a relative term, but the images zoom in enough to show the shape of the dark object's shadow. Also in the top-ten list of large stars is Betelgeuse. note: 1 AU = one Astronomical Unit, or one Earth-sun distance] in diameter. One weird binary is the star which is the goat that Auriga (the Charioteer) is holding (epsilon Aurigae).
