Is sirius bigger than earth?
Yes. Sirius actually consists of two stars. The main object, Sirius A is not only bigger than Earth but is almost twice the diameter of the sun. The secondary star, Sirius B is a collapsed remnant of a star called a white dwarf. It is slightly smaller than Earth but far denser.
Is sirius a cold?
No. Sirius is far from a cold star. Sirius is actually a binary system about 8.6 light years away. Sirius A is a white main sequence star just over twice the size of the sun. Sirius B is a white dwarf stellar remnant of about 0.978 solar masses. The temperature of the two stars are far higher than that of our sun. The sun is about 5778 Kelvin, Sirius A is almost twice that at 9,940 K and Sirius B is many times that at 25,200 K.
How far apart are Sirius A and Sirius B?
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).

Does Sirius satellite radio works in Europe?
I honestly was not sure of the answer to this question so I have done some research for you. I have found that unfortunately Sirius satellite radio does not work in Europe as Sirius does not have coverage in that area. I believe in Europe you can get satellite radio from a company called Worldspace.

Is Sirius far from the solar system?
Sirius is approximately 8.6 light years distant. It is normally the brightest star in the night sky
What star is the brigtest of all-stars the sun or the sirius star?
Neither. The Sun only appears bright because it is close. Sirius is far larger and brighter than our Sun. Our Sun is probably in the top 40% of all stars in the Milky Way, while Sirius is probably in the top 5%. But there are many other stars that are far brighter even that Sirius.
Why isn't Polaris the brightest star?
How bright a star appears depends on how bright it is and how far away it is. While, on the whole Polaris is a very bright star it is also very far away, at least 350 light years, which makes it appear dimmer. The brightest star in the night sky is Sirius, one of the closest stars to Earth at only 8.6 light years. The brightest star overall, as viewed from Earth, is the sun, which is a quarter of a million times closer to us than the next nearest star.
Sirius has a parallax of 0.377 arc seconds How far away is it from earth in arc seconds?
1.232 light years
The color age and temperature of a star is deternmined mostly by the?
Sirius is the brightest star in the night sky with a visual apparent magnitude of -1.47, almost twice as bright as the next brightest star Canopus. It is also known colloquially as the "Dog Star", reflecting its prominence in its constellation, Canis Major (English: Big Dog). It is the subject of more mythological and folkloric tales than any other star apart from the sun. The heliacal rising of Sirius marked the flooding of the Nile in Ancient Egypt and the 'Dog Days' of summer by the Ancient Greeks, while to the Polynesians it marked winter and was an important star for navigation around the Pacific Ocean. What appears as a single star to the naked eye is actually a binary star system, consisting of a white main sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The reason for its brightness is not its intrinsic luminosity but its closeness to the Sun; at a distance of 2.6 PC or 8.6 light years, Sirius (more correctly the Sirius system) is one of our near neighbours. Sirius A is only about twice as massive as the Sun and, with an absolute magnitude of 1.42, has far less intrinsic luminosity than other bright stars such as Canopus or Rigel. The Sirius Star System is between 200 and 300 million years old and comprised of two bright bluish stars early in its existence. The more luminous star, Sirius B, consumed its resources and became a red giant before shedding its outer layers and collapsing into its current state as a white dwarf around 120 million years ago.
How far is the star eliptic from earth?
I don't think there is such a star. If you mean the ecliptic, that's not a star - it is the plane of Earth's orbit.
