Parent Category: Stars
Sirius is located southeast from the Orion constellation. Sometimes known as the dog star, Sirius is the brightest star in the night sky.
1.6×10^28 m^3 (cubic meters) (assuming sphere) 4×10^18 mi^3 (cubic miles) 5×10^-6 AU^3 (astronomical units cubed) 1.6×10^34 mL (milliliters)
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 Betelgeuse...
Like other stars, Sirius formed when a cloud of gas and dust calleda nebula collapsed under the force of gravity. As the cloudcollapsed it formed two masses that heated up until the nuclearfusion of hydrogen ignited, turning the two masses into stars by200 to 300 million years ago. The result was a...
It is the brightest star in the night sky.
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...
All of the elements in the periodic table
You might be referring to a quasar.
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...
Since Sirius is recorded in the earliest astronomical records, it's discovery was in ancient times
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".
They craped in the toilet and Looked up in the sky and said sh!t Sirius is moving away from earth.
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
Right next to Sirius A. Both go around their common center of mass, once every 50 years.
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...
Sirius is a double star; the larger of the pair is twice the massof the Sun and about 1.7 times the Sun's radius. So it would beabout 740,000 miles radius.. and would be about five times theSun's volume.
There is no constellation named Sirius. Sirius is the brighteststar in the constellation Canis Major, which for an observer facingsouth, 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 andhelium. Sirius B is mostly carbon and oxygen in a highlycompressed, 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.
The Sun likes the earth's atmosphere, but the earth's atmosphere thinks the sun is really annoying. It is a very complex relationship (FACEBOOK OFFICIAL). But I have a feeling they will break up soon. Try not be nosy about it though, the sun oftentimes has a fiery vengance.
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.
Sirius is a single star, in the constellation Canis Major, justeast of Orion. It's visible at some time of night during roughly 9 months of theyear. The best time of year to see it depends entirely on what time of nightyou like to go outside and look. If you're like most people, and do your...
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
No. Sirius consists of two stars. Sirius A is larger than the sunbut is not a giant. Sirius B is a white dwarf,
Our sun is a yellow star. All stars with a G class rating are yellow stars.
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 awhite star about 1.7 times the diameter of the sun and would easilyfit inside the orbit of Mercury. The secondary body, Sirius B is awhite dwarf that is slightly smaller than Earth, though possessingabout the same mass as the sun.

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 theconstellation Canis Major, which, if you are looking south, appearsbelow and to the left of Orion. Sirius B itself is too dim to beseen from Earth; the vast majority of the light from Sirius is fromSirius A. Even then, as a binary system,...
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.
There are different classes of star that can be called dwarf stars.Some are ordinary stars that have masses similar to or less thanthat of the sun. These include red dwarfs, orange dwarfs, andyellow dwarfs. A brown dwarf is a star that failed to initiatenuclear fusion. A white dwarf is the collapsed...
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 ismoving more or less toward us.
No. There is no such thing as an "earth-like star" as Earth is aplanet, not a star. Sirius A is a star that is larger and brighterthan 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 aGalaxy of many billions of stars. Sirius is a few hundred millionyears old, younger than most of the stars in the Milky Way.
It is not real. Sirius is a two-star system containing only SiriusA and Sirius B.
Sirius is easy to identify because it is the brightest star in thenight sky.
Yes. Sirius is the brightest star in the night sky.
If you are not initiated you cant see it.
Arcturus: 37 ly . Altair: 16.8 ly . Betelgeuse: 640 ly . Sirius: 8.6 ly So Sirius is the closest.
As seen from Earth, yes, Sirius is the brightest star in the nightsky. 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 twostars, 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 starconstellation 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 .
star is a huge ball of fire (hydrogen and helium). It don't have any specific colour. Like nebula star nursery, has orange, yellow and red mostly and supernova, example crab nubula is green, white draft grey and white with purple field around it and black draft is black and whitish around. So star...
It already has. Sirius B is a white dwarf, the dense remnant of adead star. While it is no longer producing energy through fusion,Sirius B still glows with the leftover heat of when it was anactive star. Because of the huge amount of heat and relativelysmall surface area, it will take trillions of...
No. Sirius is a binary star system consisting of a white mainsequence 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 adead 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 theclosest stars to Earth. On a cosmic scale, any star close enough tobe visible to the naked eye is fairly close. The farthest stars inthe known universe are in other galaxies, billions of light yearsaway.
No. Stars are too hot to support life.
Polaris is about 430 light-years away from Earth, or 4.07 * 10 18 meters, or 2.53 * 10 15 miles.
