LatvianNounstars Declensions From Wiktionary under the GNU Free Documentation License. A star is a massive, luminous ball of plasma that is held together by gravity. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth. Other stars are visible in the night sky, when they are not outshone by the Sun. Historically, the most prominent stars on the celestial sphere were grouped together into constellations, and the brightest stars gained proper names. Extensive catalogues of stars have been assembled by astronomers, which provide standardized star designations. For most of its life, a star shines due to thermonuclear fusion in its core releasing energy that traverses the star's interior and then radiates into outer space. Almost all elements heavier than hydrogen and helium were created by fusion processes in stars. Astronomers can determine the mass, age, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. The total mass of a star is the principal determinant in its evolution and eventual fate. Other characteristics of a star are determined by its evolutionary history, including the diameter, rotation, movement and temperature. A plot of the temperature of many stars against their luminosities, known as a Hertzsprung-Russell diagram (H–R diagram), allows the age and evolutionary state of a star to be determined. A star begins as a collapsing cloud of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Once the stellar core is sufficiently dense, some of the hydrogen is steadily converted into helium through the process of nuclear fusion. The remainder of the star's interior carries energy away from the core through a combination of radiative and convective processes. The star's internal pressure prevents it from collapsing further under its own gravity. Once the hydrogen fuel at the core is exhausted, those stars having at least 0.4 times the mass of the Sun expand to become a red giant, in some cases fusing heavier elements at the core or in shells around the core. The star then evolves into a degenerate form, recycling a portion of the matter into the interstellar environment, where it will form a new generation of stars with a higher proportion of heavy elements. Binary and multi-star systems consist of two or more stars that are gravitationally bound, and generally move around each other in stable orbits. When two such stars have a relatively close orbit, their gravitational interaction can have a significant impact on their evolution. Stars can form part of a much larger gravitationally bound structure, such as a cluster or a galaxy. From Wikipedia under the
GNU Free Documentation License What supermassive star is known or believed to have the largest number of smaller stars orbitting it? Q. I see many stars that are even bigger relative to our sun than our sun is to most of the other planets in our solar system. Surely there have to be some multiple-star systems arranged in which tiny stars such as our Sol orbit much more massive stars such as VY Canis Majoris.

You can read more about multiple star systems and about Castor in the sources below: Answered by unknown - Fri Jul 17 08:50:45 2009 What are those perpendicular lines in photos of stars called and why are they there? Q. In astronomical photos, some stars, especially the larger and closer ones, show cross-like patterns of light centered at the star itself. What is this phenomenon called, and why does it occur? I know it is not lens flare, as that is ghostlike circles of increasing diameter coming from a major light source. Asked by mal7798 - Sun Apr 19 08:19:28 2009 - - 3 Answers - 0 Comments A. They are called "Diffraction spikes." In reflector telescopes, there is a four vane apparatus (called a "spider" ) to hold the secondary mirror in front of the primary mirror. Even tho it is engineered to affect the image as little as possible, it still scatters some light. This effect is worst on the brightest stars in the image because those bright star have more light to scatter. These spikes are absent in a image taken by a refractor telescope. Refractors, instead, suffer from a rainbow ring around the brightest stars with purple light on the outside of the ring.

Q. I seen this person get 42 stars for asking if he should give roses for a first date and I never received a star for an election question. If I make my questions more difficult about the Canidates will I receive a star? Asked by Curious George - Sun Apr 13 01:32:47 2008 - - 4 Answers - 0 Comments A. I don't know if you'll get any in the Election section. Seems like a lot of 'sensitive' type guys get the most. The rose guy for example and one dad who was talking about not being able to buy much stuff for his kids, the soft-hearted type of questions that we don't do here in Elections lol. Edit: I gave you one just to be nice even though I know you're anti-Obama :) Answered by Tracy H - Sun Apr 13 01:40:08 2008 From Yahoo Answer Search: "stars" 'Aliens In The Attic' Star Carter Jenkins Joins The Long, Long ...
