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 change as the gravitational pull of Sirius A would be greater. The water on earth would boil off and it would become a barren planet that could not support life. Even Mars may be too hot to support life if Sirius A were our star.
What else can I help you with?
How long does Sirius take to orbit the sun?
Sirius does not orbit the Sun.
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.
What is the exact mass of Sirius?
The exact mass of Sirius, which is a binary star system consisting of Sirius A and Sirius B, is approximately 2.1 solar masses (where one solar mass is the mass of our Sun). Specifically, Sirius A has a mass around 2.1 times that of the Sun, while Sirius B, the white dwarf companion, has a mass about 0.98 solar masses. Together, their combined mass is slightly less than 3 solar masses.
How would you describe the Sirius?
As seen from Earth, Sirius is the brightest sky in the night sky. It is best on view during the months of winter in the northern hemisphere. It can be found by finding the constellation of Orion, and using Orion's Belt, to follow down low and to Orion's left.
How many earth can fit in sirius?
Well, darling, Sirius is about twice the size of our dear old Sun, and the Sun could fit about 1.3 million Earths inside it. So, if we do the math (which I'm sure you could handle), Sirius could fit around 2.6 million Earths inside it. But hey, who's counting? Just know it's a whole lot of Earths.
What would happen if the sun was replaced by R136a1?
R136a1's heat would probably vaporize all of the planets.
What size is the star Sirius?
Sirius is a double star; the larger of the pair is twice the mass of the Sun and about 1.7 times the Sun's radius. So it would be about 740,000 miles radius.. and would be about five times the Sun's volume.
What is the size is Sirius?
Sirius has a mass 0.978 that of the Sun, and a radius 0.0084 times that of the Sun. No, actually Sirius A has a mass of 2.2 that of the Sun and a radius 1.711 times that of the Sun.
What is the size of Sirius?
Sirius is a binary star system consisting of two stars: Sirius A and Sirius B. Sirius A is the larger and more luminous star, with a diameter of about 1.7 times that of the Sun. Sirius B is a white dwarf star with a diameter of about 12,000 kilometers, roughly the size of Earth. The distance between the two stars is about 20 AU (astronomical units).
Can you live on Sirius?
No sirius is a star much hotter than the sun.
Is Sirius a giant?
No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
How many light years is Sirius from the sun?
Sirius is located about 8.6 light years away from the Sun.
How long does Sirius take to orbit the sun?
Sirius does not orbit the Sun.
Is the sirius star 10 times bigger then the sun?
No. In terms of diameter Sirius is 1.7 times the size of the sun.
Is Sirius brighter than the sun?
Yes it is much bigger.Probably 5 suns can fit in sirius.Not only is sirius bigger but it is much hotter as well.
Is the star Sirius larger than earths orbit around the sun?
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 the sun.
How much would you weigh on Sirius A?
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.
