The brightest star visible from any part of Earth is Sirius in the constellation Canis Major the Greater Dog. Sirius is sometimes called the Dog Star. Most people in the Northern Hemisphere notice Sirius in the southeast – south – or southwest on evenings from winter to mid-spring. February evenings are a grand time to see it. It’s also fun to spot Sirius as it ascends in the east before dawn on late summer mornings.
As seen from around the world, Sirius rises in mid-evening in December. By mid-April, Sirius is setting in the southwest in mid-evening.
Sirius is always easy to find. It’s the sky’s brightest star! Plus, anyone familiar with the constellation Orion can simply draw a line through Orion’s Belt to find this star. Sirius is roughly eight times as far from the Belt as the Belt is wide.
Sirius is well known as the Dog Star, because it’s the chief star in the constellation Canis Major, the Big Dog. Have you ever heard anyone speak of the dog days of summer? Sirius is behind the sun as seen from Earth in Northern Hemisphere summer. In late summer, it appears in the east before sunrise – near the sun in our sky. The early stargazers might have imagined the double-whammy of Sirius and the sun caused the hot weather, or dog days.
And with good reason. Because Sirius much hotter star than our sun. Its surface temperature is about 17,000 degrees Fahrenheit in contrast to our sun’s 10,000 degrees F. With slightly more than twice the mass of the sun and just less than twice its diameter, Sirius puts out 26 times as much energy. It’s a main-sequence star, meaning it produces most of its energy by converting hydrogen into helium through nuclear fusion.
Although white to blue white in color, Sirius might be called a rainbow star, as it often flickers with many colors.
In ancient Egypt, the name Sirius signified its nature as scorching or sparkling. The star was associated with the Egyptian gods Osiris, Sopdet and other gods. Ancient Egyptians noted that Sirius rose just before the sun each year immediately prior to the annual flooding of the Nile River. Although the floods could bring destruction, they also brought new soil and new life. Osiris was an Egyptian god of life, death, fertility and rebirth of plant life along the Nile. Sopdet – who might have an even closer association with the star Sirius – began as an agricultural deity in Egypt, also closely associated with the Nile. The Egyptian new year was celebrated with a festival known as The Coming of Sopdet.
BINARY STAR SYSTEM
Did you know that Sirius is actually not a single star? It is a binary star system consisting of two white stars orbiting each other with a separation of about 20 AU (roughly the distance between the Sun and Uranus). The age of the system has been estimated at around 230 million years.
Its companion, Sirius B, is a star that has already evolved off the main sequence and become a white dwarf. Currently 10,000 times less luminous in the visual spectrum, Sirius B was once the more massive of the two.
Sirius B is one of the more massive white dwarfs known. This mass is packed into a volume roughly equal to the Earth’s. In other words, it is tiny in comparison to Sirius A which is more the double the size of our sun.

SIRIUS A/B: ELIZABETH’S AND MY HOME STARS
For Elizabeth and me, the Sirius binary starts also have a special personal significance. Sirius. Sirius A is Elizabeth’s home star. Sirius B is mine. Many millions of years ago, I was a multiverse portal keeper on Sirius B.
That was one of the many fascinating things I learned on my astral birthday and initiation nearly 9 years ago – on Feb 25, 2009.
