Sirius is the brightest star in the entire sky, twice as bright as its nearest competitor, Canopus, in the southern constellation Carina.
Sirius gets its name from the Greek word for "searing" or "scorching" and refers to its pre-dawn rising in August during the hottest time of the year.
Sirius has a companion star called the Pup, a tiny but exceedingly dense white dwarf only about 7,000 miles (11,200 km) across (smaller than the Earth!) but with 98 percent the mass of the sun.
In the distant future, when the sun runs out of nuclear fuel to "burn," its core will contract to form a white dwarf, while the solar atmosphere will poof off into space to form a temporary wreath of glowing gas called a planetary nebula.
Someday, the same will happen to our brilliant pal, Sirius, and instead of one tiny star orbiting a big one, twin white dwarfs will whirl about the other.
