Since time immemorial, we’ve wondered, “Is the Sun just a typical star?”
In the 17th century, Christiaan Huygens estimated the distance to Sirius, assuming that it was a distant sun-like star.
His result, 0.4 light-years across, did not take into account intrinsic stellar differences.
Stars come with a variety of properties: mass, color, temperature, ionization, metallicity, age, and so on.
Although the Sun is not a unique cosmic exception, it is not entirely typical either.
With about two sextilions (~2 x 1021) Stars within the visible universe, how do they compare?
Most of the stars that exist today formed long ago: ~11 billion years in the past.
Our Sun, which was born 4.6 billion years ago, is younger than 85% of all stars.
The majority of stars are red dwarfs: cool, low-mass, and long-lived.
Our Sun, a G-magnitude star, is more than 95% larger than the stars.
Most of the stars are less metallic than our stars: some of the heavy elements are present.
Our Sun has a greater enrichment than ~93% of all stars.
Only half of the stars are as single as our Sun. The other half is within multiple star systems.
We are not usually luminous.
The ratio of luminosity to the total mass of stars is three times that of ours.
Ordinary, it would seem, includes a colossal scope.
