Sirius is about twice the size of our sun.
Because a white dwarf star is the core leftover from a bigger star and the core is the densest part of the star so although the star is smaller than the sun it has a similar mass as it is more dense
  Sirius and Betelgeuse are two of the brightest stars in the night sky, with Sirius being the brightest and Betelgeuse being the 9th brightest. Betelgeuse is in the wonderful constellation of Orion. Sirius is in the nearby constellation of Canis Major. They are very easy to spot, with...
Like other stars, Sirius formed when a cloud of gas and dust called  a nebula collapsed under the force of gravity. As the cloud  collapsed it formed two masses that heated up until the nuclear  fusion of hydrogen ignited, turning the two masses into stars by  200 to 300 million years ago. The...
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...
Eight channel electronic music for trumpet, soprano, bass clarinet and bass is the composition of 'Sirius' by Karlheinz Stockhausen [August 22, 1928-December 5, 2007].
All stars, including Sirius, are made up of hydrogen, carbon, and helium, mainly.
Sirius A a white main sequence star is the brightest star in the night sky as seen from Earth and has been known of since there has been astronomy and possibly even before that. It's dimmer partner Sirius B a white dwarf was first theorised in 1844 by German astronomer Friedrich Bessel based on...
It is in the constellation of Canis Major.
I live near the equator, and see Sirius towards the east (January 2014, after sunset). If you live in the northern hemisphere, you will see it more towards the south-east; if you live far south from the equator, you will see it more towards the north-east. Note that Sirius is currently the second...
Most of the particularly bright stars have several names; a Chinese name, and Indian name, a polynesian name, and so on. In the Middle East, the Egyptians and Babylonians had their own names, which were interpreted or modified by first the Greeks, then the Romans. The first document that we might...
Sirius B is a faint white dwarf companion of Sirius A It has an apparent magnitude of +8.3 and an absolute magnitude of +11.18
No. Sirius A is many times larger than Sirius B.
Sirius is not part of our Solar System, so it is not appropriate to talk about "other objects in the solar system".
Sirius is actually a binary star system. Sirius A has a spectral type of A1 and is a star on the main sequence. Sirius B is a white dwarf
Sirus B is a small, dim companion star of Sirius A. The current best theory is that the Dogon, who were not all that isolated or primitive, told an early expedition about their myths relating to Sirius, whereupon the scientists of that expedition told them what they knew about Sirius. When a later...
There is no constellation named Sirius. Sirius is the brightest  star in the constellation Canis Major, which for an observer facing  south, appears below and to the left of Orion.
It's very difficult to age individual stars, but it is estimated that the Sirius system is about 200 - 300 million years old. Sirius B became a white dwarf about 120 million years ago. Big stars like Sirius rarely last more than half a quarter billion years.
Sirius is actually two stars. Sirius A is mostly hydrogen and  helium. Sirius B is mostly carbon and oxygen in a highly  compressed, degenerate state.
Sirius is one of the brighter stars in our sky, and is easily visible without a telescope. It has been known since the first man looked up at night.
If you weighed 100lb on Earth you would weigh about 5,400 lb for about a millisecond before you were incinerated and turned into vapour. Sirius A is a star about twice the size of our Sun.
0.987 (SM) Solar Masses.
Sirius is the brightest star...Polaris is bigger then Sirius, Polaris is 360 to 820 light years away from earth, and Sirius is only 8.6 light years away. The Sirius star is known as the dog constalation, The polaris star is found at the tip and corner of the big dipper and the little dipper
for being falsely accused for killing Peter Pettigrew and a dozen other muggles.
No. Sirius consists of two stars. Sirius A is larger than the sun  but is not a giant. Sirius B is a white dwarf,
Sirius was named after the word 'blazing' which fits because it is the brightest star in the night sky AND twice the size and brightness
Sirius is the brightest star in the constellation Canis Major, the Large Dog.
Sirius is a star. It is the brightest star, after the sun, in the northern hemisphere.
No. Sirius is a binary star system. The main body, Sirius A is a  white star about 1.7 times the diameter of the sun and would easily  fit inside the orbit of Mercury. The secondary body, Sirius B is a  white dwarf that is slightly smaller than Earth, though possessing  about the same mass as...

Its possible to see Sirus. Its the brightest star you can in the Sky.
Sirius does not orbit the Sun.
Sirius is about 8.6 light years away from us.
Sirius, which consists of both Sirius A and Sirius B is in the  constellation Canis Major, which, if you are looking south, appears  below and to the left of Orion. Sirius B itself is too dim to be  seen from Earth; the vast majority of the light from Sirius is from  Sirius A. Even then, as a...
Yes - Sirius is a blue-white star - the hottest type of star there is.
No, but Sirius B is,
Sirius is a star not a galaxy.
Yes, easily. Sirius is the brightest star in the night sky.
how can 1 BTU = 1055 joule ?
Sirius A is about twice as massive as our sun, but has a surface temperature of around 10000 degrees Kelvin, compared with our suns surface temperature of around 5800 Kelvin. The Earth and all of the other planets would be a lot hotter if they remained at their current orbit, though the orbits would...
The origin of Leo the Lion is by the Greeks in 40BC. The word Leo is latin for lion.
There is only one star in the solar system, Sol, our sun, and therefore the largest star.
Sirius does not have any known planets.
This is related to the name of the constellation: Canis Maioris, that is, the Big Dog.
The spectral lines of Sirius are blueshifted because the star is  moving more or less toward us.
No. There is no such thing as an "earth-like star" as Earth is a  planet, not a star. Sirius A is a star that is larger and brighter  than the sun.
Sirius B Sirius B has a radii of 0.0084 solar radii.Barnard's star has a radii of 0.196 solar radii.
Lots of them. One nearby example is Alpha Centauri.Another,allegedly, is Sirius...
No. Sirius is part of Canis Major's nose. Winter triangle or the Big Dog.
No, because they are not. Sirius A and B are just two stars in a  Galaxy of many billions of stars. Sirius is a few hundred million  years old, younger than most of the stars in the Milky Way.
It is not real. Sirius is a two-star system containing only Sirius  A and Sirius B.
Sirius is easy to identify because it is the brightest star in the  night sky.
Yes. Sirius is the brightest star in the night sky.
If you are not initiated you cant see it.
Arcturus: 37 lyAltair: 16.8 lyBetelgeuse: 640 lySirius: 8.6 lySo Sirius is the closest.
As seen from Earth, yes, Sirius is the brightest star in the night  sky. In terms of actual brightness, no.
Sirius is 8.6 light years from Earth, while Polaris is 434 light years. So yes, Sirius is the closer of the two.
Its size is very little and its temperature is hot
Sure - the two attract each other. In the case of a double star - as Sirius A and Sirius B - both revolve around their common center of mass.
You can't see constellations with a telescope. In fact, you may be looking straight into one, but you'll never notice it until you come out from behind your telescope.
Sirius is actually a binary star system. Sirius A has an apparent magnitude of -1.46 whereas Sirius B has an apparent magnitude of 8.3
Sirius A has a spectral class of A1V [See related questions]
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).
No. There is no such thing a a cold star. Sirius consists of two  stars, both of which are hotter than the average star.
Look up the Wikipedia article, "Sirius", for more details. Briefly, it is: the brightest star in the sky (however, some planets, which also look like stars, are brighter); 8.6 light-years away; a double star; one of the components (Sirius B) was the first white dwarf to be discovered.
Vega is brighter than Capella. Vega is closer to Earth than Capella. Vega is blue-white, Capella is yellow-ish. The name Vega comes from Arabic, whereas the name Capella comes from Latin. The meaning of Vega is a type of bird, the meaning of Capella is a type of mammal. :o)
No, they not. Sirius constellation is Canis Major while Pistol star  constellation is Sagittarius
Answer:Most Creationists have no problem with the speed of light. Only the "young Earth" or "young universe" branch have to deal with the issues of light sources "billions of light-years" away. Some have rather interesting ideas about how to reconcile the two ideas, ranging from "God started the...
The amount of time between successive passes of the star Sirius across the meridian is 23 hrs 56 minutes.
It already has. Sirius B is a white dwarf, the dense remnant of a  dead star. While it is no longer producing energy through fusion,  Sirius B still glows with the leftover heat of when it was an  active star. Because of the huge amount of heat and relatively  small surface area, it will take...
No. Sirius is a binary star system consisting of a white main  sequence star and a white dwarf.
most stars are made of mainly hydrogen, a little helium and traces of other gases like oxygen
Sirius B is a white dwarf, meaning it is already the remnant of a  dead star. That star died about 120 million years ago.
As we see it, it is the brightest star in the night sky..
Polaris is much hotter.
No. At a distance of only 8.6 light years, Sirius is one of the  closest stars to Earth. On a cosmic scale, any star close enough to  be visible to the naked eye is fairly close. The farthest stars in  the known universe are in other galaxies, billions of light years  away.
No. Stars are too hot to support life.
is made out of star material
It was deduced mathematically in 1844 by Bessel, but Sirius B was  not seen until 1862 by Alvin Clark.
Yes. It is in the constellation of Canis Major. As we see it, it is the brightest star in the night sky. But maby we can see a brighter star
Gas doesn't weigh much, since a white dwarf is the core of a red giant. (the core is basically all the star's weight-the gases don't weigh much, so the weight doesn't differ much if a star lets go of all of its gas, since that's how white dwarfs are made)
Sirius is 8.6 light years away.
Neither Sirius A nor Sirius B have any known planets.
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.
Sirius A has a spectral class of A1V meaning it is a white to blue-white star on the main sequence.
Sirius is considerably hotter than Antares.
It doesn't. At least, no time travel has been achieved so far.
Sirius is located in Canis Major at RA 6h 45m 08.9173s Decl -16° 42' 58.017". It is about 8.6 light years away.
