How long is a year on Sirius?
Sirius is a star, so it doesn't have an orbit like the planets do. Thus, you can't calculate a year for Sirius. All you can do is estimate its age in Earth years.
Is sirius a star or planet?
The star Sirius is not a planet or even a single star but is in fact a binary star, or two stars that orbit each other. Together, these two stars are often called The Dog Star, as they are the brightest object in the constellation Canis Major - or The Big Dog. The stars, named Sirius A and Sirius B, orbit each other about 20 Astronomical Units (the distance from the Sun to the planet Uranus) that takes about 50 years to complete on orbit. Right now, they appear to be moving away from each other and will reach their maximum separation on the year 2019. At a distance of roughly 8.6 light years, the Sirius binary star system is actually relatively close to us. Sirius A (the larger of the two binary stars) is also extraordinarily bright, about 25 time brighter than our sun. These two factors make Sirius one of the top ten brightest stars in our night sky. While Sirius A is very large and bright, Sirius B (the smaller of the two binary stars) is significantly smaller than it's companion - about the size of our Earth. But even at it's small size, Sirius B still has nearly the same mass as our Sun. That much mass in such a tiny space means more surface gravity (about twice that of Sirius A) and more heat (about 2.5 times that of Sirius A). Just because it's small, doesn't mean it's not awesome. Sirius is considered a wintertime star, usually only seen between the months of December and March. It is part of the Winter Triangle asterism along with Betelgeuse and Procyon. So if you're in the Northern Hemisphere and the weather begins to turn cold, take a look into the southern night sky and find Sirius, The Dog Star!

Why is Ethan Fromes consideration of the star Sirius ironic to his circumstances?
I'm not familiar with the book, nor the time frame. However, judging by the location and the time of year (Snow on the ground), it seems unlikely Sirius would have been visible at that (Starkfield, MA) location. However, if there had been a late snow fall after mid march it is quite possible Sirius could have been visible on the horizon.
What time of the year is the constellation Sirius visible?
Sirius is a single star, in the constellation Canis Major, just east of Orion. It's visible at some time of night during roughly 9 months of the year. The best time of year to see it depends entirely on what time of night you like to go outside and look. If you're like most people, and do your gazing between dinnner and bed-time, then Winter and early Spring are the best seasons.
Were Severus and James Sirius potter in the last Harry Potter movie twins?
No, James Sirius was a year older than Albus Severus s forward sentence
What are facts about Canis Minor?
Canis Major means "great dog". It was discovered by Ptolemy. It contains Sirius, the dog star. Sirius is the brightest star in the sky (after the sun). It has a right ascension of 7h. It has a declination of -20 degrees. 4 of its stars have planets. The "dog days of summer" are so called because Canis Major was visible during the hottest time of the year. It was sometimes considered as Orion's hunting dog. There is also a Canis Minor.
What happened to Sirius's Black's parents?
His father, Orion, died the same year (1978) as Regulus Black (Sirius' brother) in unkown circumstances. Walburga Black, Sirius' mother, died in 1985 but her portrait remained in her house, 12 Grimmauld Place.
Is there a minimum comtract for XM and Sirius radio?
Usually a contract term is one year.
What did Sirius Black write in his letter to Harry Potter that would make his next year at Hogwarts more enjoyable?
Sirius also enclosed in his letter to Harry a note giving him permission to visit Hogsmeade on weekends. The Dursleys hadn't given Harry permission at the beginning of third year to visit Hogsmeade, leading to Harry using his cloak to sneak out. Whereas with written permission from Sirius, his godfather, he would no longer have to sneak around next year.
